Question

If 4 moles of sodium react how many mole of chlorine gas will react

Answer 1

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

Answer: 2 moles of chlorine gas will react.

Step-by-step 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 =
`(1)/(2)` moles of
`Cl_2` gas.

Then , 4 moles of sodium will react with :

`(1)/(2)* 4\text{moles of } Cl_2=2 moles`

2 moles of chlorine gas will react.
