Short Answer

Expert verified

Part (a) . 2H3PO4(aq)+3Ca(OH)2(s)→Ca3(PO4)2(s)+6H2O(l)

Part (b).localid="1653209628452" KHCO3(s)+HNO3(aq)→H2O(l)+CO2(g)+KNO3(aq)

Step by step solution

01

Given Information (part a) 

Chemical reactions include changes that just include the places of electrons in the framing and breaking of compound connections between iotas, with no change to the cores and can frequently be depicted by a compound condition

02

Explanation Part (a)

The balanced reaction is,

2H3PO4(aq)+3Ca(OH)2(s)→Ca3(PO4)2(s)+6H2O(I)

03

Explanation Part (b)

The balanced reaction is,

KHCO3(s)+HNO3(aq)→H2O(I)+CO2(g)+KNO3(aq)
