The balanced equation
2Na₃PO₄+3Ca(NO₃)₂⇒6NaNO₃+Ca₃(PO₄)₂
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
