The chemical equation for the combustion of acetylene (C2H2) is given below. 2C2H29) + 502(9)—-4C02(g) + 2H2O(g)
What volume of oxygen at STP is required for the complete combustion of 100.50 mL of C2H2?

309.2 ml of oxygen

Explanation:

2 ( 12X2 +Ix 2 ) = S2 ml

O2 = 5 x 16 x 2 = 160 ml

volume of O2 needed = 160×100. 5 / 52 = 309.2 ml

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
