(B) The chemical formula for sodium dihydrogen pyrophosphate is $Na_2H_2P_2O_7$. By examining its structure,we can count the specific bonds: $1$. $P-H$ bonds: There are no $P-H$ bonds in the structure. Count = $0$. $2$. $P-O-P$ bonds: There is one bridging oxygen atom between the two phosphorus atoms. Count = $1$. $3$. $P-O-H$ bonds: There are two $P-OH$ groups attached to the phosphorus atoms. Count = $2$. $4$. $P=O$ bonds: Each phosphorus atom is double-bonded to one oxygen atom. Count = $2$. Wait,re-evaluating the structure provided in the image: - The structure shows two $P$ atoms linked by an $O$ atom $(P-O-P)$. - Each $P$ is bonded to one $OH$ group $(P-OH)$. - Each $P$ is double-bonded to one $O$ atom $(P=O)$. - One $P$ is bonded to an $O^-$ and the other $P$ is bonded to an $O^-$. Counting based on the provided image: - $P-H$ bonds: $0$ - $P-O-P$ bonds: $1$ - $P-O-H$ bonds: $2$ - $P=O$ bonds: $2$ Therefore,the correct counts are $0, 1, 2, 2$.
