This is due today please help me! thank you! <3 Fe2O3 (aq) + 6HCl (aq) 2FeCl3 (aq) + 3H2O (l)
If 4.00 moles of HCl are used with excess iron (III) oxide, how many moles of water are produced?

and

C3H8(g) + 5O2(g) 3CO2(g) + 4H2O(g)
How many moles of water would be produced if 95.2 L of oxygen gas are consumed?

ok whats the question if not i cannot you i need question and need a thing to answer

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7

cu2o
