Answer 1

it 1:1 I had an online review and thats the answer it told me it was.
-Hope this helped you

Answer 2

Answer : The mole ratio of
`PCl_3` to
`PCl_5` is 1 : 1 ratio.

Explanation :

The balanced reaction will be,

`PCl_3+Cl_2\rightarrow PCl_5`

From the balanced reaction, we conclude that

1 mole of
`PCl_3` react with the 1 mole of
`Cl_2` to give 1 mole of
`PCl_5`

Hence, the mole ratio of
`PCl_3` to
`PCl_5` is 1 : 1 ratio.
