1st you need to find the mole ratio between KClO3 and O2.  To find that you need to take the coefficents of each of the compounds.  That gives a ratio of 2:3.

Now we find out how many each unit is:
2x = 12
x = 6

Now we multiply it by 3 to find the number of moles of O2
3(6) = 18 mol O2.

How can I tell how many electrons in each energy level? When my question states "third sublevel" does this mean sublevel P?
nikitadnepr [17]
Sorry for the delay! My internet is a bit bad.
P is the third sublevel. Each sublevel (the angular momentum quantum number), has its own number:
<span>s = 1, p =3, d = 5, f = 7</span>
The number of electrons for each is:
s-2
p-6
d-10
f-14
It's easier to just memorize these numbers, but the equation for determining the sublevel number is 2n (n = the principal quantum number). The principal quantum number is based on the period the element is in.

34 atoms of carbon react with 22 molecules of hydrogen gas. How many molecules of methane will be formed &amp; what will be left
pychu [463]
Each carbon atom will react with 4 hydrogen atoms to form methane (C H_{4}) Since there are 2 hydrogen atoms in a hydrogen molecule (H_{2}) then each carbon atom will react with 2 hydrogen molecules. Since there are 22 hydrogen molecules half as many methane molecules will be formed, so 11. Then we can subtract 11 from 34 to find the number of carbon atoms left over.

So in summary, 11 methane molecules will be formed and there will be 23 carbon atoms left over.
