Answer:
This reaction is a single replacement reaction.
Explanation:
Step 1: Data given
A single-replacement reaction is a reaction in which one element replaces a similar element in a compound. The general form of a single-replacement (also called single-displacement) reaction is:
A+BC→AC+B
A decomposition reaction is a reaction in which a compound breaks down into two or more simpler substances. The general form of a decomposition reaction is:
AB→A+B
A double-replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds. The general form of a double-replacement (also called double-displacement) reaction is:
AB+CD→AD+BC
A combustion is a high-temperature exothermic (heat releasing) redox (oxygen adding) reaction between a fuel and an oxidant, usually atmospheric oxygen.
Whenever we complete a combustion reaction of a hydrocarbon (compound of C and H) we generally have the same products formed: CO2 and H2O.
Na (s) + H2O (l) → NaOH (aq) + H2 (g)
This reaction is not a decomposition because we don't break down a compound.
This reaction is not a combustion because we don't oxidze a compound to form CO2 and H2O
This reaction is a replacement reaction. But only a single replacement reaction because one element replaces a similar element in a compound
