<span> first of all by using Gay Lussac Volume
1L of N2 reacts with 3L of H2
so that it can give 2L of NH3
so1.2L of N2 reacts with 3.6L of H2
so that it can give 2.4L of NH3 at same temp and pressure
hope it helps

To know if an equation is balanced you need to check and see how much of each molecule is on either side of the arrow. Right now you have 1-Ca, 2-H, 2-Cl on the left side of the arrow and 1-Ca, 2-Cl, and 2-H on the right side too. Because all the molecules are equal on both sides this means that the equation is balanced. So in front of the CaCl2 there is an assumed coefficient of 1. The answer is 1.
As we all know that energy is the ability to do work
nona-, 9 it shows the prefix with the correct corresponding number
Explanation:
This prefixes are used commonly in chemistry to name compounds and you may find them when hydrocarbons are named.

hexa- for 6
hepta- for 7
octa- for 8
nona- for 9
deca- for 10
The correct answer for the question is nona-, 9.
