When a mixture of 10.5 g of acetylene (C2H2) and 10.5 g of oxygen (O2) is ignited, the resultant combustion reaction produces CO2 and H2O. How many grams of C2H2 are present after the reaction is complete?

How many grams of O2 are present after the reaction is complete?

How many grams of CO2 are present after the reaction is complete?

How many grams of H2O are present after the reaction is complete?

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
