Explanation:
The question pretty much requires us to find the amount of moles of each compounds based on the number of moles of O given.
H2SO4
1 mol of H2SO4 contains 4 mol of O
x mol of H2SO4 would contain 3.10 mol of O
x = 3.10 * 1 / 4 = 0.775 mol of H2SO4
C2H4O2
1 mol of C2H4O2 contains 2 mol of O
x mol of C2H4O2 would contain 3.10 mol of O
x = 3.10 * 1 / 2 = 1.55 mol of C2H4O2
NaOH
1 mol of NaOH contains 1 mol of O
x mol of NaOH would contain 3.10 mol of O
x = 3.10 * 1 / 1 = 3.10 mol of NaOH
It is to find an unbiased group of people unrelated to the event and it is a way for even the least patriotic citizens to serve their country. It also means there IS A JURY, if there wasn't; then it would come done to the whims of the judge.
Ok so next time maybe add that it explains the number of covalent bonds in the atom because... (and then explain CaF2 tendencies in following the octet rule, like if it adds to 8 or isn’t completed yet.)
If this isn’t enough I would highly recommend asking your teacher after class even if they don’t like you or are one of THOSE teachers they gotta help you or it’s not fair for them to count you off points.
