what type of reaction is naoh + hcl --> nacl + hoh double replacement single replacement synthesis combustion
what type of reaction is naoh + hcl --> nacl + hoh double replacement single replacement synthesis combustion
Answer
Explanation:
Step1: Analyze reaction components
In the reaction $\text{NaOH}+\text{HCl}\rightarrow\text{NaCl}+\text{H}_2\text{O}$, the sodium ($\text{Na}^+$) from $\text{NaOH}$ and the hydrogen ($\text{H}^+$) from $\text{HCl}$ swap places with the hydroxide ($\text{OH}^-$) from $\text{NaOH}$ and the chloride ($\text{Cl}^-$) from $\text{HCl}$.
Step2: Recall reaction - type definitions
A double - replacement reaction is one where the positive and negative ions of two ionic compounds exchange places. This reaction fits that definition. A single - replacement reaction has one element replacing another in a compound. A synthesis reaction combines two or more substances to form one product. A combustion reaction involves a substance reacting with oxygen to produce heat and usually carbon dioxide and water.
