Answers
Answer:
Combination; double displacement and combustion reactions
Explanation:
Combination reaction
(also known as a synthesis reaction) is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product).
Such reactions is represented by equation of the following form:
X + Y → XY.
Double displacement reaction
Also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products.
Combustion:
A chemical reaction between substances, usually including oxygen and usually accompanied by the generation of heat
The given questions are:
a) Combination Reaction
b) Double Displacement Reaction
c) Double Displacement Reaction
d) Combustion Reaction
