H2(g)+p4(s)ph3(g) what the answer ?

Phosphorus has 4 in it and hydrogen has 3 in it. in order to balance it, we have to put 4 in front of phosphine so that the phosphorus on the product side has an equal amount as to the one on the reactant side.

the only one left to balance is hydrogen and so in order to balance it we put a 6 on h2 because the hydrogen in the product size becomes 12 (4 * 3).

therefore the hydrogen on the reactant side becomes 12 as well (6 * 2)

The balanced chemical reaction is:

[tex]6H_2(g)+P_4(s)\rightarrow 4PH_3(g)[/tex]

Explanation:

In a balanced chemical equation number of atoms of all the elements are equal on the reactant side and product side.

The given equation of the chemical reaction is not balanced.

[tex]H_2(g)+P_4(s)\rightarrow PH_3(g)[/tex]

Balancing the chemical reaction:

Balance the atoms of all the elements besides hydrogen and oxygen. Balance phosphorus atoms by writing 4 in front of phosphine gas on the product side.

[tex]H_2(g)+P_4(s)\rightarrow 4PH_3(g)[/tex]

Now balance the hydrogen atoms. There are 12 hydrogen atoms on the product side and 2 hydrogen atoms on the reactant side. So by writing 6 in front of hydrogen gas on the reactant side.

[tex]6H_2(g)+P_4(s)\rightarrow 4PH_3(g)[/tex]

So, the balanced chemical reaction is:

[tex]6H_2(g)+P_4(s)\rightarrow 4PH_3(g)[/tex]
