1. The problem statement, all variables and given/known data Chloroethane, reacts with Oxygen according to the equation below: 2C2H3Cl + 5O2 → 4CO2 + 2H2O +2HCl How many moles of CO2 are produced when 3.0 moles of choloroethane and 3 mol of O2 are reacted? When 50cm3 of 1mol/dm3 HCl is mixed with 50cm3 of 1mol/dm3 NaOH, the temp of the resulting solution increases by 6 °C. What will be the temp change when 100cm3 of each of these solutions are mixed? I'm sorry I don't really have any idea on how to attempt these properly, could you guys give me a hint? Please!!! The help would be greatly appreciated !!
