Question 81: One of the forms of a naturally occurring solid compound P is usually used for making the floors of houses. On adding a few drops of dilute hydrochloric acid to P, brisk effervescence are produced. When 50 g of reactant P was heated strongly, than 22 g of a gas Q and 28 g of a solid R were produced as products. Gas Q is the same which produced brisk effervescence on adding dilute HCl to P. Gas Q is said to cause global warming whereas solid R is used for white-washing.

(a) What is (i) solid P (ii) gas Q, and (iii) solid R.
(b) What is the total mass of Q and R obtained from 50 g of P ?
(c) How does the total mass of Q and R formed compare with the mass of P taken ?
(d) What conclusion do you get from the comparison of masses of products and reactant ?
(e) Which law of chemical combination is illustrated by the example given in this problem ?
