A) +3, +4, +5
B) +4, +3, +5
C) +3, +5, +4
D) +5, +3, +4
Correct Answer: A
Solution :
\[{{H}_{4}}{{P}_{2}}{{O}_{5}}:4\times 1+2\times a-5\times 2=0\] \[a=+\,3\] \[{{H}_{4}}{{P}_{2}}{{O}_{6}}:4\times 1+2\times a-6\times 2=0\] \[a=+\,4\] \[{{H}_{4}}{{P}_{2}}{{O}_{7}}:4\times 1+2\times a-7\times 2=0\] \[a=+\,5\]You need to login to perform this action.
