Chemistry Unit 8 Vocabulary Flashcards ionicons-v5-c

Actual Yield

The amount of product produced in the lab

Avagadro's number

6.02 x 10^23, which represents the number of particles in a mole

Atom

A single, unbonded particle or element

Coefficient

Number in front of a variable

Excess Reactant

the substance that is not used up completely in a reaction

Formula unit

An ionically bonded particle that contains a metal and a nonmetal

Law of Conservation of Mass

the law that states that mass cannot be created or destroyed

Limiting reactant

A reactant that is totally consumed during a chemical reaction, limits the extent of the reaction.

Mole

6.02 x 10^23 (one unit of anything)

Mole to mole ratio

small whole number ratio from balancing coefficients

Molecule

A covalently bonded particle (Nonmetals only)

Molar Mass

the mass of one mole of a substance from the periodic table

Particle

The smallest part of a substance that can be separated physically (such as an atom)

Percent yield

What percent of what was expected to be made: Actual yield/theoretical yield x 100.

Stoichiometry

The calculation of quantities in chemical reactions

STP (standard temperature and pressure)

conditions of 0.00°C and 1 atom of pressure
