ethene burns in oxygen according to the equation:
C2H4(g) + 3O2 ---------> 2CO2(g) + 2H20(g)
1. wat volume of ethene, measured at r.t.p., would burn completely in 10.8 dm cube of oxygen?
2. if a solution of sodium carbonate containing 12g of carbonate ions reacts completely with hydrochloric acid, wat volume of carbon dioxide would be produced at s.t.p.?
