redox reactions include which types of reactions?\na. double - replacement, combustion, synthesis, decomposition\nb. single - replacement, synthesis, decomposition, combustion\nc. single - replacement, double - replacement, acid - base, synthesis\nd. acid - base, decomposition, double - replacement, synthesis
Answer
Brief Explanations:
Redox reactions involve a transfer of electrons. Single - replacement reactions involve one element replacing another in a compound and have electron transfer. Synthesis reactions (e.g., formation of a compound from elements) and decomposition reactions (breaking of a compound into elements or simpler compounds) can involve electron transfer. Combustion reactions, which are reactions with oxygen, also involve electron transfer. Double - replacement and acid - base reactions are usually not redox as they mainly involve ion exchange and proton transfer respectively without significant electron transfer.
Answer:
B. Single - replacement, synthesis, decomposition, combustion
