Question

A few crystals of kno3 are heated in a hard glass test tube equation

Answer 1

2KNO3------> 2KNO2 + O2.......

Answer 2

Dear student,

● Answer -
KNO3 decomposes to KNO2 evolving O2 gas.
2KNO3 --> 2KNO2 + O2

● Explanation -
- When few crystals of potassium nitrate (KNO3) are heated in glass tube, it decomposes to potassium nitrite (KNO2) and oxygen (O2).

2KNO3 --> 2KNO2 + O2

- Oxygen gas is evolved in this reaction.

Hope this solved your queries.
Thanks for asking.
