To balance a chemical reaction, we need to remember that the number of each atom in the reactant and the product side of the equation should be equal. So, from the reaction <span>P4(s) + Cl2(g) = PCl3(l), there are 4 P atoms in the reactant, the P atoms in the prodcut side should be 4 as well. We balance as follows:

</span> P4(s) + 6Cl2(g) = 4PCl3(l)
<span>
Therefore, the coefficient of the PCl3 should be 4.

</span>

I dont get dependent and independent variables if someone can explain it and give an example that wpould be great!​
Musya8 [376]
An independent variable is the variable that is changed or controlled in a experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured. so like is math. the input variable is the independent variable. the output is the dependent variable because it depends on the input variables.
