Under certain conditions, natural gas (methane, CH4) will react with a limited supply of oxygen to yield a mixture of soot (C(s)), carbon monoxide, and water, but no other products. This is commonly known as an incomplete combustion. If the number of carbon atoms in the soot that forms is always three times the number of carbon monoxide molecules that are produced, how many oxygen molecules react with 9 molecules of methane

i believe it is a.) released into

explanation:

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%

so what is the problem with your lab report and whats the subject of the lab report? i will you
