An unknown compound contains only carbon, hydrogen, and oxygen (CxHyOzCxHyOz). Combustion of 5.00 gg of this compound produced 7.33 gg of carbon dioxide and 3.00 gg of water. How many moles of carbon, CC, were in the original sample? Express your answer to three significant figures and include the appropriate units. answer  0.167 mol How many moles of hydrogen, HH, were in the original sample? Express your answer to three significant figures and include the appropriate units.

When a hydrocarbon such as butane (C4H10) is combusted, it produces water vapor and CO2 given in the reaction below: 2 C 4 H 10 + 13 O 2 ⟶ 8 C O 2 + 10 H 2 O How many moles of O2 are required to combust 78.89 g of butane? Round to the nearest whole number.

Jessica is doing her pre-lab homework for Chemistry. She is asked to predict how many grams of oxygen gas are produced if 40.0g of potassium chlorate is decompose according to this balanced chemical equation shown. 2KCIO3(s)-2KCI(s)+302(g) She performs the following calculation, and gets 15.7 g of O2 as her answer. g KCIO mol KCIO, mol O, 80, 1 mol KC1O3 122.55 g KC1O3 3 mol 02 32.00 g 02 1 mol 0, 2 mol KC1O, The next day when her group performs the experiment they obtain an actual yield of 15.2 grams of oxygen gas. What is the percent yield for the experiment? report your answer to the tenths place, i.e. one decimal place.

c38(g)+5o2(g)=3co2(g)+4h2o(g) how many moles of carbon dioxide would be produced from 20.45 moles of oxygen gas

Gaseous methane CH4 reacts with gaseous oxygen gas O2 to produce gaseous carbon dioxide CO2 and gaseous water H20. If 0.817g of carbon dioxide is produced from the reaction of 0.48g of methane and 3.6g of oxygen gas, calculate the percent yield of carbon dioxide

In the following reaction, 2 N2 (g) + 5 O2 (g) → 2 N2O5 (g), how many moles of N2O5 are produced by 12.1 moles of O2 gas?

Aqueous hydrobromic acid (HBr) reacts with solid sodium hydroxide (NaOH) to produce aqueous sodium bromide (NaBr) and liquid water (H,O). If 0.299 g of water is produced from the reaction of 1.6 g of hydrobromic acid and 1.2 g of sodium hydroxide, calculate the percent yield of water. Be sure your answer has the correct number of significant digits in it.
