Question

6. The 2.8 g of nitrogen gas was allowed to react with 0.6 g of hydrogen gas to produce 3.4 g

of ammonia. Show that these observations are in agreement with the law of Conservation

of mass.

7. If 12 g of carbon is burnt in the presence of 32 g of oxygen, how much carbon dioxide will

be formed?​

Answer 1

Answer:

6) ⇔Mass of nitrogen gas=2.8g

⇔Mass of hydrogen gas=0.6g

⇔Total mass of reactants=2.8+0.6=3.4g

⇔Given mass of ammonia(product)=3.4g

⇔Since mass of reactants=mass of product, these observations are in agreement with the law of conservation of mass.

7) According to law of conservation of mass, CO2 formed will be 32+12 = 44g
