Reaction Types

Photosynthesis reaction

• sunlight + carbon dioxide + water --> oxygen + glucose

• sunlight + carbon dioxide + glucose --> oxygen + water

• carbon dioxide + glucose --> oxygen + water + sunlight

• sunlight + water + glucose --> oxygen + carbon dioxide

Respiration

• glucose + carbon dioxide --> water + oxygen

• glucose + oxygen --> water + carbon dioxide

• water + carbon dioxide --> glucose + oxygen

• carbon dioxide + oxygen --> water + glucose

Corrosion is the result of...

• reduction of a metal ion

• oxidation of a metal

Rust causes...

• weakening of iron structures

• strengthening of iron structures

An example of a combustion reaction is...

• freezing water

• rusting

• a fire

• oxidation of a metal

Photosynthesis is important because...

• oxygen is consumed in the process

• oxygen is produced in the process

Combustion

• fuel + oxygen --> water + carbon dioxide

• fuel + water --> oxygen + carbon dioxide

• oxygen + carbon dioxide --> fuel + water

• water + carbon dioxide --> fuel + oxygen

Acid + metal -->

• carbon dioxide + salt

• hydrogen gas + salt

• water + salt

• water + carbon dioxide
