The water having more dissolved $O_{2}$ is:

What are the main states of matter?

If equal amounts of methane and oxygen are mixed in an empty container at $25 \, ^oC$,what is the fraction of total pressure exerted by oxygen?

The ratio of $\frac{C_p}{C_v}$ for inert gases is

In which of the following gas mixtures does Dalton's Law of Partial Pressure not apply? Why?
$(i)$ $CO_2 + O_2 + N_2$
$(ii)$ $CO + O_2$
$(iii)$ $NH_3 + HCl$
$(iv)$ $HCl + O_2$

When an equal weight mixture of $SO_2$ and $O_2$ is taken in an empty container,the ratio of the partial pressure of $O_2$ to the total pressure is ......
