Question

Complete and balance each of the following:

a. ${\mathrm{H}}_3{\mathrm{PO}}_4\left(aq\right)+\mathrm{Ca}\left(\mathrm{OH}{)}_2\right(s)⟶$

b. ${\mathrm{KHCO}}_3\left(s\right)+{\mathrm{HNO}}_3\left(aq\right)⟶$

Short answer

Part (a) . $2{\mathrm{H}}_3{\mathrm{PO}}_4\left(aq\right)+3\mathrm{Ca}{\left(OH\right)}_2\left(s\right)\to {\mathrm{Ca}}_3{\left(P{O}_4\right)}_2\left(s\right)+6{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$

Part (b).localid="1653209628452" $\begin{array}{rl}& {\mathrm{KHCO}}_3\left(s\right)+{\mathrm{HNO}}_3\left(aq\right)\to {\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+{\mathrm{CO}}_2\left(g\right)+{\mathrm{KNO}}_3\left(aq\right)\end{array}$

Step-by-step solution

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

Explanation Part (a)

The balanced reaction is,

$2{\mathrm{H}}_3{\mathrm{PO}}_4\left(aq\right)+3\mathrm{Ca}\left(\mathrm{OH}{)}_2\right(s)\to {\mathrm{Ca}}_3{\left({\mathrm{PO}}_4\right)}_2(s)+6{\mathrm{H}}_2\mathrm{O}(\mathrm{I})$

Explanation Part (b)

The balanced reaction is,

${\mathrm{KHCO}}_3\left(s\right)+{\mathrm{HNO}}_3\left(aq\right)\to {\mathrm{H}}_2\mathrm{O}\left(\mathrm{I}\right)+{\mathrm{CO}}_2\left(g\right)+{\mathrm{KNO}}_3\left(aq\right)$
