Theoretical Maximum Mass and Yield Concepts

These flashcards cover key vocabulary and concepts related to theoretical maximum mass, yields, and their calculations in chemical reactions.

Theoretical Yield

The maximum mass of a product that can be obtained from a given amount of reactant, calculated based on stoichiometric ratios.

Percent Yield

A measure of the efficiency of a reaction, calculated as (Actual Yield / Theoretical Yield) x 100.

Actual Yield

The measured amount of product obtained from a chemical reaction.

Conservation of Mass

A principle stating that mass is neither created nor destroyed in a chemical reaction.

Molar Mass of NO2

The mass of one mole of nitrogen dioxide, calculated as 14 (N) + 16 * 2 (O) = 46 g.

Molar Mass of O2

The mass of one mole of oxygen gas, calculated as 16 * 2 = 32 g.

First Law of Thermodynamics

The law stating that energy cannot be created or destroyed, only transformed.

Efficiency of a reaction

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

Total Mass Conservation in Reactions

The principle that the total mass of reactants equals the total mass of products.

62.3% Yield

The percent yield calculated from an actual yield of 5.3 grams and a theoretical yield of 8.51 grams.
