Question

Match the statements in List I with those in List II.

Answer 1

$\left(A\right)-\left(3\right)$

Green house gases contain water vapour $\left(H_{2}O\right),C{H}_4,N_{2}O,C{O}_2$. These gases can trap heat and let the melting of glaciers and cause global warming.

$\left(B\right)-\left(5\right)$

Carbogen is a mixture of $C{O}_2$ and $O_2$ gas. It is mixture of colourless odourless gas. Both $C{O}_2$ and $O_2$ are non combustile.

$\left(C\right)-\left(4\right)$

Oxygen is a gas used for respiration. The $O_2$ we get it from surrounding plants, trees.

$\left(D\right)-\left(1\right)$

$Iron+Oxygen+Water⟶Rust$

$4Fe+3O_2+2H_{2}O⟶2F{e}_2{O}_3\cdot H_{2}O$

$\left(E\right)-\left(2\right)$

The magnesium continues to burn in the carbon dioxide, forming some black specs of carbon and white magnesium oxide.
