2 C,H.(g) + 7 O;(g) → 4 CO,(g) + 6 H,O(g) Calculate the volume of CO2 produced when 80.0 L of O2 completely reacts with excess C,Hat STP. O 2.04 L O 45.7 L O 62.9 L O 89.8 L O 140. L

Carry only 1 decimal point on all atomic weights (X.X). What is the mole fraction of O2 in a mixture that is 283.6 g N2, 145.1 g O2, and 5.111 g CO2?

2 H3PO4(s) --> 3 H2(g) + 2 P(s) + 4 O2(g) Using the reaction above, show step by step how many liters of oxygen can be created if I start with 0.7156 grams of H3PO4 solid at STP?

Please answer

4 NH3 (g) + 5 O2 (g) →→ 4 NO  (g) + 6 H2O (l) What is the mole-mole factor (ratio) of H2O to NH3?

1. Determine the Empirical Formulas from the % Composition data. Compound A: Compound A has a % composition (by mass) of 59.96% C, 26.62% O, and 13.42% H Compound A effuses 1.478 times faster than Xenon gas Compound B: Compound B has a % composition (by mass) of 62.04% C, 27.55% O, and 10.41% H Compound B effuses 1.063 times faster than Xenon gas

For NH3 (g) + O2 (g) ---> NO (g)  + H2O (g), balance the equation and find the number of liters of O2 (g) that can react with 1.5L of NH3 (g) if the gases are at the same temperature and pressure.
