Written from the section, each card quoting the span it came from. The ones you miss come back sooner.
What this needs
Learn these first — this section will not make sense without them.
Nothing in the algebra book is a prerequisite for this section.
What this touches
Algebra that turns up here. Not a blocker, but this is where you will see it used.
Balancing a half-reaction's charge by adding the right integer number of electrons to each side — for example Fe → Fe³⁺ + 3e⁻ — is isolating an unknown coefficient so both sides of an equation are equal, the same move already licensed as a prerequisite for balancing nuclear equations, reused here for redox half-reactions in acidic or basic solution.
