Chemical Reactions

Question 1

What is a combination reaction and a example

Answer 1

Combination reactions (sometimes known as synthesis reactions) occur when multiple reactants combine to form a single product. carbon + oxygen ⟶ carbon dioxide

Question 2

What is a composition reaction and an example

Answer 2

Decomposition reactions occur when a single reactant breaks apart to form multiple products.
calcium carbonate ⟶ calcium oxide + carbon dioxide

Question 3

What happens in a neutralisation reaction

Answer 3

Neutralisation reactions occur between acids and bases, to form water and a salt.

Question 4

What happens in an acid carbonate reaction

Answer 4

Acid-carbonate reactions occur between acids and carbonates to form salt, water and carbon dioxide.
