Question

In a reaction, 8.6 g of solid lead nitrate is heated. The products were
5.5g of lead oxide, 2.7 g of nitrogen dioxide and 0.4 g of oxygen gas.
Show that these observations are in agreement with law of
conservation of mass.

Answer 1

Explanation:

To show that these observations are in agreement with the law of conservation of mass .... simply check whether the mass of reactants is equal to the mass of products or not!!!

8.6 g -------- (5.5g + 2.7g + 0.4g)

8.6g = 5.5

2.7

+ 0.4

-------

8.6

--------

hence,,, 8.6=8.6 !!!!
