Answer:
The coefficient of H3PO4 is 1
Explanation:
The equation is H3PO4(aq) + NaOH (aq) → Na3PO4(aq) + H2O (l)
To balance the reaction, we first balance the Na atoms: On the right there are 3 Na atoms, so on the left we multiply NaOH by 3
The number of P atoms on the left is 1, the number of the P atoms on the right is also 1. So, this is already balanced.
On the left there are 6 H atoms, on the right we have 2H atoms, so e have to multiply H2O by 3.
On the left we have 7 O atoms, on the right, now we have also 7O atoms.
So this is already balanced.
The fully balanced reaction is H3PO4 (aq) + 3NaOH(aq) → Na3PO4(aq) + 3H2O(l)
The coefficient of H3PO4 is 1
