Question

x,y, and z in the following processes are respectively:-

(i) $P_2{O}_5+x\to C{a}_3(P{O}_4{)}_2$

(ii) $2C{u}_{2}O+C{u}_{2}S\to y+S{O}_2$

(iii) $F{e}_2{O}_3+3CO\to z+3C{O}_2$

• A. $3Ca$,$CuS{O}_4$,Fe
• B. $3Ca(OH{)}_2$,6Cu,FeO
• C. $3CaO,6Cu,2Fe$
• D. $3Ca{O}_2$,CuS,FeO

Answer 1

The correct option is C $3CaO,6Cu,2Fe$

Reactions:

(i) $P_2{O}_5+3CaO\to C{a}_3(P{O}_4{)}_2$

Here, $x$ is $3CaO$

(ii) $2C{u}_{2}O+C{u}_{2}S\to 6Cu+S{O}_2$

$y$ is $6Cu$

(iii) $F{e}_2{O}_3+3CO\to 2Fe+3C{O}_2$

$z$ is $2Fe$

So, the correct option is $C$
