L9 - Limiting Reagents & Yield

Flashcards about acids and chemical reactions

Acid

Donates an H+ (hydrogen ion).

Reaction of acid with metals

A type of chemical reaction where a metal reacts with an acid to form a salt and a gas.

Reaction of acid with carbonates

A type of chemical reaction where a carbonate reacts with an acid to form a salt, water, and a gas.

Chemical reactions: reactants and products

The reactants are on the left-hand side, and the products are on the right-hand side.

Aqueous solution

The cation and anion components of a substance when it is dissolved in water.

Spectator ions

Ions that do not participate in the reaction and are excluded from the net ionic equation.

Quantifying Chemical Reactions

Quantitatively describing a chemical reaction by measuring the amounts of reactants and products.

Molar mass

Have values on the periodic table that tell us how much mass one mole of a substance has.

Mole

A universal count of the number of items

Stoichiometric coefficients

The ratios of substances in a chemical equation.

Limiting reagent

The reactant present in the least amount that limits the amount of product that can be formed

Percent yield

The ratio of the actual yield to the theoretical yield, expressed as a percentage.

Decomposes

Breaks apart.

Actual yield

Experimentally collected.

Theoretical yield

Is calculated by assuming 100% conversion.
