Balance the following reaction: _Na3PO4+_Ca(NO3)2-->_NaNO3+_Ca3(PO4)2
erica [24]

The balanced equation

2Na₃PO₄+3Ca(NO₃)₂⇒6NaNO₃+Ca₃(PO₄)₂

<h3>Further explanation</h3>

Given

Reaction

_Na3PO4+_Ca(NO3)2-->_NaNO3+_Ca3(PO4)2

Required

Balanced equation

Solution

Give a coefficient

aNa₃PO₄+bCa(NO₃)₂⇒cNaNO₃+Ca₃(PO₄)₂

Ca, left=b, right = 3⇒ b=3

P, left=a, right = 2⇒a=2

Na, left=3a, right=c⇒3a=c⇒3.2=c⇒c=6

The equation becomes :

2Na₃PO₄+3Ca(NO₃)₂⇒6NaNO₃+Ca₃(PO₄)₂
