Find the pH for a hydronium ion concentration of [H^+]=3.2*10^(-4)M. Round to 1 d.p.

 

I dont even know where to start for this problem

 

Thanks in Advance

Why do you not know where to start for this question?

Were you not paying attention in class?

Do you not read the examples in you study text?

 

Google how to calculate hydronium ions. Solving this is very simple. Even an idiot can do it.

...I'm sure you qualify.

I belive that googling it is cheating, Furthermore if any "Idiot" Can do it it shouldnt be that hard for you to share how to do it. Hopfully the next person who answers will be more helpful and kind. But thanks anyway wink

If Googling is cheating then it sure as h**l is cheating to post the question on here.

 

You are lazy! You just want someone to spoon-feed you ... and someone did.

 

If you don’t learn how to learn on your own, you will never learn anything.

 

Here’s something you might learn if you researched this question: This is NOT a bloody calculus question!

 

It really helps to know what subject your question belongs to. When you learn this, then you may have an IDEA where to begin.

Guest answerer clearly got out of bed on the wrong side today and I am not condoning his/her aggressive words.

 

But the suggestion to  "Google how to calculate hydronium ions" was most likely a good one.

If you learn to look things up on the net you can usually get more comprehensive answers and sometimes you learn more.

Often it is just knowing what words to use to get the answer you want that is the hard bit and guest has given you a good suggestion.

As for saying that googling is cheating, when you are here looking for an exact answer, that was a rather crazy thing to say.

OMG! You are a male version of a classic Goody Two-shoes.  LMAO!

 

 As for reporting me, by all means, report away.

All of the moderators and (probably) the administrator will instantly recognize who I am. (Melody, of course, already has.)

 

You don’t know who I am because you’ve not read enough of the forum’s posts and/or lack the cognitive skills for this kind of discernment.  Incidentally, one of my longest posts is a response to one of your posts (and a comment by EP): https://web2.0calc.com/questions/we-should-really-put-this-site-on-brave-as-a-verified-website#r7  Did you ever read it? (Now you know.)

 

I see that you’ve created a forum version of AITA (Am I the Asshole). 

Your question is very vague, but will see how the voting pans outI’m waiting with bated breath.

I find it astonishing that this site in general would be specifically approved by a teacher and not the net in general.

there are many brilliant teaching resources in You Tube and on the net in general.  

Maybe it is a stranger danger thing idk.

Anyway, your explanation is reasonable.

 

Most of the time it is best to ignore Gingers tirades.

I might delete some of thiese posts later later for now I am just going to lock the question so that no more posts can be added.

I suspect web2.0calc.com, and probably some others sites, were specifically recommended by the teacher as a resource because it’s relatively obscure (known only to a few million) compared to Google and You Tube (known to billions). I doubt the teacher specifically forbids the use of Google and You Tube, because, as you say, they have brilliant teaching resources. They may not have been explicitly recommended because their use is so obvious. 

 

I do know one (now retired) high-level university mathematics professor who absolutely forbade the use of the net for researching solutions to math questions. The syllabus for his class stated clearly that any student violating this restriction will receive a failing grade and face expulsion. I LMAO after reading the syllabus: I thought for any given term where a university may offer this kind of advanced mathematics, there might be 30 to 40 students in all the universities around the world who could possibly understand this esoteric math enough to take such a class. Good luck in finding this information and analysis on the net.  LOL

 

As for stranger danger, this site is potentially a greater risk (because of the Private Messaging) compared to Google or You Tube. Fortunately, in the past eight years, I’ve only heard of two instances of criminal level harassment –both by the same person, on this forum. 

 

Generally, the biggest risk to students on this forum is contracting CDD –Contagious Dumbness Disease, (which they can get anywhere), and having a troll snarl and growl at them. This may be rude and off-putting to some, but it’s not criminal, and I do not throw the younger students off the bridge –only adults and older students that are obnoxious brats from heII.

 

This type of trolling is sometimes an effective method of reaching into the ever-expanding mind of a young student and disrupting the complacent, self-narrative that often gives rise to intellectual laziness. Ideally, the self-narrative will change enough to allow for a greater and accelerated assimilation of information and knowledge, allowing the student to reach a higher potential, faster.

 

Younger students usually run when I troll them. Elijah defended his position –I’m rather impressed. I think Elijah will be a wondrous student by the time he enters university.

 

Considering this, I think you should add this thread to the Sticky Topics rather than blanking the posts. (you can –or I can star-out the peppery words, if you wish).  I understand that this thread is a briar patch in a diverse garden. Large mammals and especially humans should not walk in such places without proper equipment. Briar patches have their own ecology; if you blank some or all of this, then this ecology may become extinct or perpetually dormant.  This seems like a waste. No one will die from reading this; the worse case is some will end their excursion with itchy pricks from the thorns. They will heal ...and life will continue.... 

 

Of course the final decision on its disposition is yours....

I like this post you have just written Ginger.

 

However, I think it would be a bit hard to justify putting the whole thread into the sticky note list.

I don't think many people look at the sticky notes anyway.  

Pity, there is some good posts in there.

I at least refer to some of them.... Mostly the 'reference material'.

 

Very occasionally someone will reference one or more of them, that always does impress and please me.   

Just as well we have you to keep track of our posts, especially our more contraversial posts.  You can always pull them from the archives upon command.

 

And now my mind has taken me to a elsewhere,  :)

 

Enjoy.

Dang, I thought for a moment I would be featured in a sticky topic 

 

All jokes aside though, Im glad you were only trolling - I legit Wouldve left this site if not. Ive had some really bad experiences with being called an idiot on forums. (Im a DIY handyman for my family).

You just do the inverse log...

 

-log[3.2*10^(-4)M]

 

so that would be:

 

-log[0.00032M]

 

\(-\log _{10}\left(0.00032M\right)\)

 

If you want decimal:

 

about -3.494850...

Vinculum, this NOT an inverse log! It’s an additive inverse of a Logarithm.

 

Also, it’s probably a good idea to NOT answer any more of lazy Elijah’s questions unless he demonstrates an attempt at answering.

i will have you know that the question was the 19th question like that, and my teacher encorages us to have peers help us. If you would look you would notice i hardley post quesions here. So when i have an isuues it would be nice to have some help from Friendly peers. You dont have to be hostile about it

If you answered 18 questions like that, then why did you not know where to begin for the question you posted? You are full of bullshit or lying, which, in this case is just a petrified form of bullshit.

 

I did look at your posts, including your bullshit comments and suggestions.  None of your questions are calculus questions nor do any require calculus solutions.  One of your latest questions is an augmented proportion rate question – requiring basic seventh grade math skills to solve, and CPhill had to chew it up and feed it to you before you understood it.  You have one basic chemistry question –generally seen in grade 10 or 11. 

 

Your posted questions range from the seventh to the eleventh grade, but they are not are not in a progressive order. Are you trying to learn ahead? That’s fine, but it’s very irritating to answer a math question from students who are two or more prerequisites behind, especially when the student is too lazy to review and (re)learn the prerequisites

 

You dont have to be hostile about it

 

I may not have to be hostile about it, but dumb and lazy are great catalysts for this attitude and behavior –especially when they occur simultaneously.

Fine ill rephrase it, This is the 19th question i did Incorrectly. And since I dont want to fail, im asking for help. And Pardon me for being unreasonably rude But how do I know im not talking to a high-school dropout? Or a person who doesnt know squat about math besides what Google feeds him. Im averging a 95 in calculus rn. This is a new concept that id like some help with. Sheesh. frown

 

How dare I ask a Chemistry Problem when theres literally people asking for simple division problems, fractions, addition. Those people dont get condemed. hmmm... Seems that you just targeted me.

... how do I know im not talking to a high-school dropout? Or a person who doesnt know squat about math besides what Google feeds him

 

You don’t know; it’s irrelevant. I only need to know a little more than you for the presented subject and question. Here’s an analogy: Let’s say were walking in the forest, discussing math and chemistry. While we’re walking, a bear comes out of the woods looking for lunch, and charges at us.   We run for our lives. I can’t outrun the bear, but I don’t need to; I only need to run faster than you... The bear gets his lunch (and a severe case of indigestion) and I live another day –and maybe long enough to complete high school.

 

Vinculum is a high school student. He’s not a dropout, but he’s not completed the requirements for a diploma; yet, he answered your chemistry question.  He knows more than you about this subject, and that all that is required.  I will point out that while his method is correct his final answer is WRONG. He made a math mistake. I recognized it instantly, but I didn’t comment on it because I was curious if you were going to step through the process to learn how to do these problems, or if you were just going to plop the answer on your homework and call it good. If you had stepped through it, you would have caught this mistake.   

 

 

How dare I ask a Chemistry Problem when theres literally people asking for simple division problems, fractions, addition. Those people dont get condemed. hmmm... Seems that you just targeted me.

 

I think chemistry problems are great! Especially when the asker knows it’s a chemistry problem.  It appears that you and Builderboi, [“I mean, I have no clue what the heck that is, but it looks like math,” source] did not know this. I’m amazed that Builderboi, who is very skilled and accomplished in advanced high school math, didn’t have a clue.

 

Chemistry, and other science questions requiring applied mathematics to solve, is a great way to learn math.  I wish there were more applied mathematics on this forum. In years past there were a lot more chemistry and physics questions, and some of them were very advanced.

...when theres literally people asking for simple division problems, fractions, addition. Those people dont get condemed. hmmm...

 

They do get condemned –that is I troll them. But only on occasion, else half the posts on this forum would be troll posts.  Here’s a post where Melody “trolls” a poster.

 

Here’s an excerpt from a post where I comment on this issue.

 

The forum is morphing into a homework cheating site for morons and, lately, retards. There is nothing new about this descent into the maelstrom of stupid: here’s a post from 2018 delineating the problems and descent into the moron  and submoron level:

 https://web2.0calc.com/questions/should-you-consider-anything-before-you-answer-a-question#r17

This post https://web2.0calc.com/questions/half-donuts_1. This third-grade question outlines the entrenched half-brain imbecile group. These brain-dead elementary questions (usually percentage questions) are asked by remediated senior high school students. 

 

... This commentary continues for several more paragraphs

You can read the rest of it here:

https://web2.0calc.com/questions/we-should-really-put-this-site-on-brave-as-a-verified-website#r7  (This post is a response to your post.)

 

Seems that you just targeted me.

 

Yes, I did target you. You are worthy. You seem to have a few more brain cells than the average of morons on here, but your extra brain cells seem to be inactive, possibly inert. You will not learn anything if others do your home work for you. If someone presents a solution to one of your questions then you need to redo the work to learn it (and to catch mistakes, like the one above). Otherwise they are just suppositories that you shove up your ass and then forget the next time you take a shit.  

 

Your life is your own, Elijah. However if you want to be something other than a turd in a cesspool of stupid, you will need to do your homework and apply yourself well beyond the minimum requirements for moronhood.  Those are the rules
