Question

When a solid B was heated in a test-tube, it gave off two gases. The two gases were separated by passing them through a plug of glass wool in a test-tube as shown below.

The first gas which evolved turned moist red litmus paper to blue. Later the other gas involved turned the litmus back to red.

1. Identify solid B 
2. Write the equation for the reaction that take place in the test tube

Answer 1

1. Identify solid B 
   Ammonium Carbonate
2. Write the equation for the reaction that take place in the test tube 
   (NH⁴)₂ CO_3(S) → 2NH_3(g) + CO_2(g) + H₂O_(l)
