Be sure to answer all parts. Hydrogen gas has been suggested as a clean fuel because it produces only water vapor when it burns. If the reaction has a 91.3% yield, what mass of hydrogen forms 424 kg of water? Enter your answer in scientific notation. 2.30

Pls help me solve this question, explain and make sure everything is correct 1000% thanks

Just need steps to the final answer

A compound containing only carbon, hydrogen, and oxygen is analyzed using combustion analysis. When 80.9 g of the compound is burned, 148.2 g of carbon dioxide and 40.5 g of water are collected. 1.) In order to determine the moles of carbon in the compound, first determine the moles of carbon dioxide that were produced from the combustion. 2.) Determine the moles of carbon present in carbon dioxide. This will be the same number of moles of carbon in the original compound. 3.) In order to determine the moles of hydrogen in the compound, first determine the moles of water that were produced from the combustion. 4.) Determine the moles of hydrogen present in the water. This will be the same number of moles of hydrogen in the original compound. 5.) Calculate the mass of oxygen in the original compound. You will need to subtract the mass of the carbon that ended up in the carbon dioxide and the mass of the hydrogen that ended up in the water from the mass of the original compound. 6.)…

Give the balanced equation for each of the following chemical reactions: (Use the lowest possible coefficients. Be sure to to specify states such as (ag) or (s). If a box is not needed, leave it blank.) a. Solid caproic acid (CH12O2) reacts with oxygen gas to produce gaseous carbon dioxide and water vapor. b. Solid iron(III) sulfide reacts with gaseous hydrogen chloride to form solid iron(III) chloride and hydrogen sulfide gas. c. Carbon disulfide liquid reacts with ammonia gas to produce hydrogen sulfide gas and solid ammonium thiocyanate (NH;SCN).
