Since you have excess Cl , the limiting factor is the H
16.2 gm of H2 is still 16.2 gm of H
Each 1.008 of hydrogen requires 35.45 gm of chlorine to form HCl
16.2 /1.008 x 35.45 = 569.732 gm Cl required
16.2 gm H + 569.732 gm of Cl = 585 .932 gm HCl
Volume of a sphere = 4/3 * pi * r^3 r = radius of sphere pi~ 3.14
If you use the radius in inches, your result will be in cubic inches (in^3)
1. cos(x) now stretch it horizontally by 4
cos (x/4) Now shift it UP by '1'
cos(x/4) +1
2. amplitude = 3/4
3. A cos (x ) wave with amplitude 1/2 has midline at 0 Now shift it UP by 5....the midline now shifts up by 5
midline is at 5 SO: y=5
For the first question, the period is '2' f= 1/period, so the frequency is ' 1/2 '
For the second question, the period is pi f= 1/period = 1/pi
After ONE year your college loan balance would be 1500 (1+.08) = 1620 if you make no paymets
Likely Lana would pay less interest on the loan as she has a HIGHER credit score !
There are 9000 numbers between 1000 and 9999 (inclusive)
Half of these are odd numbers A = 4500
1000 is divisible by 5 as is 9995 1 + (9995-1000)/5 = 1800 = B
A+B = 4500 + 1800 = 6300

Here is a graph of a standard bell curve: (ya just have to memorize the divisions)
6.5 m would be at the peak
Each line represents an oarfish 1.5 m shorter
The 16% total line is over to the left.....One line from the mean 6.5 - 1 line = 6.5-1.5 = 5 m
....so 16% are shorter than 5m
Cos (23pi/2) = cos ( pi/2) = 0 Sin(theta) = 0 at nowhere BETWEEN 0 and pi/2
it DOES equal 0 AT 0 But your question stated theta>0
Bummer. You're sure this is true? Do the best YOU can....sometimes math comes easier to some than others, but if you keep at it, YOU will become better than you were !
