QUESTION 38What type of reaction is the following?4 Fe (8) + 3 O2 (g) → 2 Fe203 (s)double displacementdecompositionSynthesis (or combination)single displacementcombustion

Answer 1

1) Chemical equation.

`4Fe+3O_2\rightarrow2FeO_3`

2) Types of reaction.

In the reaction above, we can see that two different compounds get together to form a new compound. This is called a synthesis or a combination.

Decomposition: A compound is broken down into simpler compounds.

Combustion: A compound containing Carbon and Hydrogen combines with oxygen.

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