The reaction 4Fe + 3O2 >> 2Fe2O3 is an example of what?

Synthesis reaction

Explanation:

A synthesis reaction involves two or more reactants combining to form a single product.

4Fe + 3O2 —> 2Fe2O3

From the above reaction, the two reactants combine to form a single product. This is clearly a synthesis reaction.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
