Question

What type of reaction is the following?H2SO4 (aq) + 2 NaOH (aq) → Na2SO4 (aq) + 2 H2O (l)-synthesis or combinationdecompositionsingle displacementdouble displacementcombustion

Answer 1

1) Chemical equation.

`H_2SO_4+2NaOH\rightarrow Na_2SO_4+2H_2O`

2) Types of reaction.

Synthesis: a compound is made from simpler materials.

Decomposition: a compound is broken down into simpler compounds.

Single replacement: one element that starts out by itself replaces another element in a compound.

Double replacement: positive and negative ions in two compounds switch places.

Combustion: a compound containing Carbon and Hydrogen combines with Oxygen gas and produces carbon dioxide and water.

3) The chemical equation above is a double displacement where H+ and Na+ switch places.
