Question

1. For the reaction, calculate how many moles of the product form when 1.77mol of Na completely reacts. Assume that there is more than enough of the other reactant. 2Na(s)+O2(g)--->Na2O2(s)

2. For the reaction, calculate how many moles of the product form when 2.69mol of O2 completely reacts.
Assume that there is more than enough of the other reactant.
2S(s)+3O2(g)?2SO3(g)

3. For the reaction shown, calculate how many grams of oxygen form when each quantity of reactant completely reacts.

2HgO(s)?2Hg(l)+O2(g)

a) 2.58 gHgO

b) 6.03 gHgO

c) 1.92 kgHgO

d) 3.67 mgHgO
