C2H4 + 3O2 -> 2CO2 +2H2O
50.0 grams C2H4 (1 mole C2H4/28.052 grams)(2 mole CO2/1 mole C2H4)(44.01 grams/1 mole CO2)
= 157 grams CO2 produced
1 to 1 ratio so 384g of NO2 is produced
43.2 grams of water
Yes. The total mass of the reactants is equal to the mass of the product.yes
2Ca + O2 --> 2CaO The molar mass of Calcium is 40g/mol. 36.5g/40g gives you 0.9125 moles of Calcium. The moles of calcium are equivalent to the moles of Calcium oxide. The answer is 0.9125 moles of calcium oxide. Correct me if I am wrong.
yes
The mass of heavy water produced when 7,00grams of oxygen reacts with excess D2 is 7,875 g.
1.25xE-3 g/mol O2 reacts completely with 2H2
The mass of the carbonate used.
1 to 1 ratio so 384g of NO2 is produced

Law of the Conservation of Mass
8.20g of carbon monoxide, how many grams of methanol will be produced?
18 grams
When an acid reacts with a metal why does the mass decrease?
The equation is 2C4H10 + 13O2 --> 8CO2 + 10H2O This means that for each mole of butane there are 5 moles of water produced. We have 7.01 g of butane = 7.01/58 moles of butane = 0.12 moles. Thus we will get 5 x 0.12 moles of water, = 5 x 0.12 x 18 g of water = 10.88 g.
43.2 grams of water
Yes. The total mass of the reactants is equal to the mass of the product.yes
