Question

rar Calculate the mass of water produced when 5.67 g of butane reacts with excess oxygen Express your answer to three significant figures and include the appropriate units. reacts with oxygen. 02. to form carbon dioxide, CO, as shown in nical equation O2(g) 10H2O(g) +8C02(g) this equation represent mole the coefficient for water (10) is utane 21 Thus, the number of duced is five times the number of at react View Available Hints) HÀ Ở Ở 3 ? coefficient for butane (2) is one of carbon dioxide (8). Thus, the butane that react is one-fourth of carbon dioxide that you Value Units Submit are given the mass of a first convert to moles before Part Calculate the mass of butane needed to produce 86.4 g of carbon dioxide Express your answer to three significant figures and include the appropriate units.

Answer 1

The butane combustion equation is: 2C4 H10 + 13O2 → 8CO2 + 10H2O
