Question

Give suitable reasons for the following
(I)We feel burning sensation in the stomach when we over eat.
(II)The crystals of washing soda change to white powder on exposure to air.

Answer 1

1. When we over eat our stomach produces more HCL to digest the food which in turn may lead to acidity. Hence we feel burning sensation in our stomach.

2. The crystals of washing soda when exposed to air lose their water of crystallization and hence become white powder.

Hope it helps.!
