Acetylene(C2H2) gas is often used in welding torches because of the very high heat produced when it reacts with oxygen(O2) gas, producing carbon dioxide gas and water vapor. Calculate the moles of water produced by the reaction of 0.090 mol of oxygen. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
