Question

Name:

a) Two carbonates that do not produce carbon dioxide on heating

b) Two nitrates that do not produce nitrogen dioxide on heating

c) A brown gas

d) A greenish yellow gas

e) A gas with rotten egg smell ​

Answer 1

A) Usually the carbonates decompose when heated to give the metal oxide and carbon dioxide. Carbonates of sodium and potassium are stable and they do not decompose on heating. So, the carbonates that do not decompose on heating are do not produce on heating.

B) The nitrates of alkali metals other than lithium do not produce reddish brown nitrogen dioxide on heating. The most common ones are sodium nitrate and potassium nitrate. They decompose to respective nitrite (residue) and oxygen (colourless ga) on heating.

C) At higher temperatures it is a reddish-brown gas that has a characteristic sharp, biting odor and is a prominent air pollutant. Nitrogen dioxide is a paramagnetic, bent molecule with C2v point group symmetry.

D) Chlorine

E) If your water smells like rotten eggs, the odor is usually caused by the levels of sulfur bacteria and hydrogen sulfide gas that can be found in a building's water supply. ... You may be surprised to know that there are over 316 chemicals found in drinking water across the US.
