Chlorine and carbon dioxide are collected through downward delivery because they are denser than air, while ammonia and hydrogen are collected through upward delivery

The correct answer is by upward displacement if air since chlorine is denser than air..

The best way of collecting chlorine gas is through upward displacement of air

Ammonia is collected by upward displacement,so A should fit in for d answer.....

please do a quick recheck... the correct answer is A..... chlorine is denser than air... so it's collected by downward displacement of air

Downward delivery of gas or upward displacement of air for gases denser or heavier than air, so B is the correct answer

chlorine is denser than air and as such is collected by downward displacement of air.... the answer is A

upward delivery or downward displacement involves the collection of gas which are denser than air
