Reactants — definition?
Substances starting a reaction, consumed during process.
Products — definition?
Substances formed as a result of a reaction.
Arrow in equations — role?
Indicates reaction direction from reactants to products.
Unbalanced equations — issue?
Atoms are not equal on both sides.
Skeleton equations — purpose?
Show formulas without coefficients, basic reaction framework.
Balancing skeleton equations — method?
Add coefficients to equalize atom counts.
Coefficients — role?
Adjust numbers to balance atoms, not formulas.
Law of conservation — states?
Atoms are neither created nor destroyed.
Word equations — purpose?
Describe reactions using substance names in words.
Balancing process — key step?
Adjust coefficients to satisfy conservation of mass.
