Flashcard: Fundamentals of Chemical Reactions and Energy — 9 carte

Chemical Reaction Balancing — principle?

Matter is conserved; only coefficients are changed.

Matter is conserved — principle?

Atoms are neither created nor destroyed in reactions.

Redox Half Equations — electrons?

Show electron transfer; oxidation loses, reduction gains electrons.

Coefficients vs subscripts — balancing?

Adjust coefficients; keep subscripts unchanged.

Oxygen's form?

Diatomic molecule: O₂.

Redox — how?

Electron transfer during reactions.

Oxidation — role?

Loss of electrons.

Reduction — role?

Gain of electrons.

Balancing oxygen atoms?

Use O₂ molecules, adjust coefficients.
