For the following unbalanced equation, what type of reaction is H_(2)+O_(2)-H_(2)O single replacement combustion decomposition synthesis double replacement

## Step 1The given chemical equation is . This equation represents a chemical reaction where hydrogen (H2) and oxygen (O2) combine to form water (H2O).## Step 2In this reaction, two or more reactants (in this case, hydrogen and oxygen) combine to form a single product (water). This is a characteristic of a synthesis reaction.## Step 3The other types of reactions listed in the options do not apply to this reaction. A single replacement reaction involves one element being replaced by another in a compound. A combustion reaction involves a substance reacting with oxygen to produce heat and light. A decomposition reaction involves a single compound breaking down into two or more simpler substances. A double replacement reaction involves the exchange of parts between two compounds.
