Question

For gas balloons A,B,C,D of equal volumes
containing H, N20, CO, CO, respectively
were picked with needle and immersed in a
tank containing CO2. Which of them will shrink
after some time​

Answer 1

Answer:

a hydrogen

Explanation:

because the balloons filled with a gas which will react with CO2, will be the ones that will shrink .Now H2 react with CO2 to form Ch2,so the amount H2 will decrease and the balloon will shrink . Also I know CO not react with CO2 , so the answer has to be a hydrogen.
