How many moles of O2 are required to burn 1.65 mol of C4H10? C4H10​​+​O2​→​CO2​+​H2O

fe 55.85 g/mol and h2o 18.02 g/mol.

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.
