7.1 Chemical Reactions Study Notes

Flashcards covering key concepts related to chemical reactions, including processes like respiration and photosynthesis, as well as the implications of chemical reactions in the environment.

Chemical Reaction

A process in which atoms rearrange to form new substances.

Respiration

The process in which oxygen and sugars are transformed into carbon dioxide, water, and energy in living cells.

Photosynthesis

The process used by plants to convert carbon dioxide and water into sugars and nutrients using sunlight.

Energy Conservation

In chemical reactions, the total energy before and after the reaction remains constant.

By-products

Substances produced in a chemical reaction that may have undesirable effects.

Green Chemistry

A field of chemistry focused on designing products and processes that minimize the use and generation of hazardous substances.

Rearrangement of Atoms

The process by which atoms are regrouped in different combinations to form new products during a chemical reaction.

Cleaning Agents

Chemicals used for cleaning, which often involve reactions with dirt and grime.

Environmental Impact

The effect that chemical reactions and processes have on the environment.

Chemical Modelling

Creating representations of chemical reactions to understand and explain observations.
