Question

na + cl₂→ nacl
total # before (reactants) elements total # after (products)
na
cl

Explanation:

Step1: Balance chlorine atoms

In \(Cl_2\), there are 2 chlorine atoms. In \(NaCl\), there is 1 chlorine atom. To balance chlorine, put 2 in front of \(NaCl\).

$$\text{Na}+\text{Cl}_2 ightarrow 2\text{NaCl}$$

Step2: Balance sodium atoms

After balancing chlorine, there are 2 sodium atoms on the product side (\(2\text{NaCl}\)). So put 2 in front of \(Na\) on the reactant side.

$$2\text{Na}+\text{Cl}_2 ightarrow 2\text{NaCl}$$

For the table:

  • For \(Na\):
  • Reactants: Before balancing (if we consider initial count as per un - balanced equation \(Na + Cl_2

ightarrow NaCl\)), assume coefficient of \(Na\) is \(x\), coefficient of \(Cl_2\) is \(y\), coefficient of \(NaCl\) is \(z\). Initially \(x = 1\), \(y = 1\), \(z = 1\). After balancing \(x = 2\), \(y = 1\), \(z = 2\). So total \(\#\) before (reactants) for \(Na\) is \(2\) (after balancing the whole equation, we look at the coefficient of \(Na\) in the balanced equation \(2Na+Cl_2
ightarrow 2NaCl\)), total \(\#\) after (products) for \(Na\) is \(2\) (from \(2NaCl\)).

  • For \(Cl\):
  • Reactants: In \(Cl_2\), the number of \(Cl\) atoms is \(2\) (since \(Cl_2\) has 2 \(Cl\) atoms and its coefficient is \(1\) in the balanced equation \(2Na + Cl_2

ightarrow 2NaCl\)). Products: In \(2NaCl\), the number of \(Cl\) atoms is \(2\) (each \(NaCl\) has 1 \(Cl\) atom and coefficient of \(NaCl\) is \(2\)).

Answer:

The balanced equation is \(2\text{Na}+\text{Cl}_2
ightarrow 2\text{NaCl}\).

  • For \(Na\) in the table: Total \(\#\) Before (reactants) \(=2\), Total \(\#\) After (Products) \(=2\).
  • For \(Cl\) in the table: Total \(\#\) Before (reactants) \(=2\), Total \(\#\) After (Products) \(=2\).
