Use the balanced equation given below to solve the problem that follows: Calculate the mass in grams of oxygen gas that must react in order to produce 50.0 g of water. 2 C4H10 + 13 O2 --> 8 CO2 + 10 H2O

88.9 g O2
115 g O2
68.3 g O2
21.0 g O2

Find the number of grams of hcl needed to react completely with .50 moles of magnesium.

Suppose that some of the compound spilled out of the crucible after it was heated. would that cause the percent by mass of water in the compound determined by the experiment to be too low, too high, or unchanged? briefly explain your answer.
