Question

HELLP PLEASE

_ Na+Cl 2 -> _NaCl
reactant side number of atoms?
Na = ?
Cl = ?
Product side number of atoms?
Na = ?
Cl = ?
what is the final equation?
_ Na+Cl 2 -> _NaCl

Answer 1

2Na+Cl2 -> 2NaCl

Step-by-step explanation:

1Na+1Cl 2 -> 1NaCl (i'm assuming they want you to balance it so ill start with 1)

Na = 1

Cl = 2 (it is 2 because it is Cl2, meaning that there are 2; but remember that you cannot change this number only coefficients)

Na = 1

Cl = 1

We need to have 2 Cl on the product side

1Na+1Cl 2 -> 2NaCl

Now we need 2 Na on the reactants side

The final equation is

2Na+Cl2 -> 2NaCl

Now it is balanced

Na = 2

Cl = 2

--

Na = 2

Cl = 2
