Question

Ethylene (C2H4 ) reacts with oxygen gas to produce carbon dioxide and water. 45.0 grams of ethylene reacts, how many grams of carbon dioxide gas will be produced?

Answer 1

4 because the sides need to balance- 2 carbons, 4 hydrogens, and 6 oxygens on each side.

Answer 2

mass of carbon-dioxide = 141.43 grams

Step-by-step explanation:

The balanced equation is written for the reaction to calculate mass of carbon dioxide produced .

C2H4 + O2 → CO2 + H2O

Balanced equation

C2H4 + 3O2 → 2CO2 + 2H2O

Molar mass of C2H4 = 12 × 2 + 4 = 28g

molar mass of CO2 = 12 + 32 = 44g × 2 moles = 88g

28 g of C2H4 produces 88 g of carbon-dioxide

45 g of C2H4 will produce ? gram of carbon-dioxide

cross multiply

mass of carbon-dioxide = (45 × 88)/28

mass of carbon-dioxide = 3960/28

mass of carbon-dioxide = 141.428571429 grams

mass of carbon-dioxide = 141.43 grams
