question\nselect all the correct answers.\nwhich chemical reaction involving water is a decomposition reaction (breaking up) and which is a synthesis (building up) reaction? if youre not sure, take a guess.\n□ water breaking down into hydrogen and oxygen is a synthesis reaction.\n□ water breaking down into hydrogen and oxygen is a decomposition reaction.\n□ hydrogen and oxygen combining to form water is a synthesis reaction.\n□ hydrogen and oxygen combining to form water is a decomposition reaction.

Answer

Brief Explanations:

Decomposition reactions break a compound into simpler substances. Water breaking into hydrogen and oxygen is an example as it's breaking up. Synthesis reactions combine simpler substances to form a more complex one. Hydrogen and oxygen combining to form water is a synthesis reaction as it's building up.

Answer:

B. Water breaking down into hydrogen and oxygen is a decomposition reaction. C. Hydrogen and oxygen combining to form water is a synthesis reaction.
