For each of the following unbalanced equations, calculate how many moles of each product would form if 0.250 mol of the reactant in boldface were to react completely. a. C12H22O11(s) → C(s) + H20(g)
b. S(s) + H2SO4(aq) ->SO2 (g) + H2O(l)
c. Bi2O3(s) → Bi(s) + O2(g)
d. H2S(g) + O2(g) → SO2(g) + H2O(l)
pls help its due tommorrow!

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
