Question

What set of coefficients will balance the chemical equation: _NaBr (aq) + _H3PO4 (aq) → _Na3PO4(aq) + _HBr (aq)

Answer 1

The Balanced chemical equation for above reaction will be :

$\small{ \mathrm{3NaBr + H_3PO_4 \rightarrow Na_3PO_4 + 3HBr}}$

The Coefficients will be :

• $NaBr - 3$

• $H_3PO_4 - 1$

• $Na_3PO_4 - 1$

• $HBr - 3$

So, Correct option is :

A. 3, 1, 1, 3
