What set of coefficients will balance the chemical equation: _NaBr (aq) + _H3PO4 (aq) → _Na3PO4(aq) + _HBr (aq)
A. 3,1,1,3
B. 1,2,3,1
C. 3,1,3,1
D. 1,1,3,3

Respuesta :

The Balanced chemical equation for above reaction will be :

[tex] \small{ \mathrm{3NaBr + H_3PO_4 \rightarrow Na_3PO_4 + 3HBr}}[/tex]

The Coefficients will be :

  • [tex]NaBr - 3[/tex]

  • [tex]H_3PO_4 - 1[/tex]

  • [tex]Na_3PO_4 - 1[/tex]

  • [tex]HBr - 3 [/tex]

So, Correct option is :

A. 3, 1, 1, 3
