Question

which best explains why the equation below is not balanced? 2na + h₂o ----> 2naoh + h₂ there is too much sodium in the reactants there is not enough water in the reactants there is not enough sodium hydroxide in the products there is too much hydrogen gas in the products

Explanation:

Step1: Count atoms on reactant side

For \(2Na + H_2O\):

• \(Na\): \(2\) atoms.
• \(H\): \(2\) atoms (from \(H_2O\)).
• \(O\): \(1\) atom.

Step2: Count atoms on product side

For \(2NaOH + H_2\):

• \(Na\): \(2\) atoms.
• \(H\): \(2 + 2=4\) atoms (\(2\) from \(NaOH\) and \(2\) from \(H_2\)).
• \(O\): \(2\) atoms (from \(NaOH\)).

Step3: Analyze imbalance

The number of \(O\) and \(H\) atoms is not the same on both sides. The imbalance is due to insufficient \(H_2O\) (reactant). With more \(H_2O\), \(H\) and \(O\) counts can balance.

Answer:

there is not enough water in the reactants
