Question

1. The compound that is suitable for drying ammonia is- (a) P4O10 (b) Concentrated H2SO4 (c) Anhydrous CaCl2 (d) CaO.
2. The SI unit of thermal conductivity is- (a) WmK (b)Wm-¹K (c) Wm-¹K-¹ (d) WmK-¹​

Answer 1

Answer:

1. Ammonia can be easily dried by passing over fresh quicklime or soda lime (granules of calcium oxide and sodium hydroxide) because it is basic in nature and doesn't react with ammonia.

2. watts per meter-kelvin

In the International System of Units (SI), thermal conductivity is measured in watts per meter-kelvin (W/(m⋅K)).

Answer 2

Answer:

1. (d) CaO

2.(c) W/mk
