if 4 moles of sodium react how many mole of chlorine gas will react
The balanced chemical equation would be written as follows:
Na + Cl2 = NaCl2
We are given the amount of sodium to be used in the reaction. This will be the starting point of the calculation. The ratio of the reactants is 1 mole is to 1 mole. Therefore, we need an equal amount of 4 moles of Cl2 gas to completely react with the sodium metal.
Answer: 2 moles of chlorine gas will react.
Explanation
\(2Na(s)+Cl_2(g)\rightarrow 2NaCl(s)\)
According to reaction, 2 mole of sodium reacts with 1 mole \(Cl_2\) gas
1 mole of sodium will react with = \(\frac{1}{2}\) moles of \(Cl_2\) gas.
Then , 4 moles of sodium will react with :
\(\frac{1}{2}\times 4\text{moles of } Cl_2=2 moles\)
2 moles of chlorine gas will react.
