Which of the following reaction is a combination reaction?
AX + YZ → XZ + Z
B2F2 + 2OH– → 2F– + OF2 + H2O
C2NaH → 2Na + H2
DS + O2 → SO2
Answer:
D. S + O2 → SO2
Read Explanation:
Only the reaction; S + O2 → SO2 is a chemical combination reaction, whereas X + YZ → XZ + Z and 2F2 + 2OH– → 2F– + OF2 + H2O are disproportionation reactions and 2NaH → 2Na + H2 is a chemical decomposition reaction.
