Question

1) a jet of hydrogen is burnt in an enclosed vessel containing 20 litres of oxygen the volume of steam produced in 40 litre at STP calculate the volume of hydrogen being burnt

2) 60 ml of carbon monoxide was mixed with 800 ml of Oxygen and igruited in an enclosed vessel calculate the total volume of gas ofter the burning is complicated all volume are measured at STP

3) Ammonia can combine with oxygen to build nitric oxide and steam as per the following equation 4llh3 (g)+5o2(g)-4No2(g)+6H2o(g) if 320 litres of ammonia are used how many litres of nitric oxide will be found out STP

4) calculate the number of moles of ammonia sulphate present in 15. 84 kg of it( H= 1 ,N= 14, C=16, S=32) 5) how many moles of sodium chloride are present in 2.9 25 gram of it?(Na=23,Cl=35.5)

5) how many grams of anhydrous sodium carbonate are present in 0.125 moles of it?
