+64 This is part of a moles to moles worksheet I need help with.
Can someone help me with this problem, I don't know how to write down the "three moles of zinc and an excess of hydrochloric acid" part into a conversion equation.
+633 The reaction states that for every atom of zinc, there are 2 atoms of hydrochloric acid
since the units are the same, we can simply change "atoms" to "moles"
So: 1 mole Zn + 2 moles HCl works in the equation
Since we have 3 moles of zinc, we can just multiply each part of the chemical reaction by 3 (chemical reactions are kind of like equations).
2 mol Zn + 6 mol HCl --> 3 mol ZnCl2 + 3 mol H2
H2 is hydrogen gas
therefore: 3 mol of hydrogen gas are created
+64 This is Chemistry, a class you should be in when you are in 10th grade.
