,📋 Questions & Verified Answers
120+ Verified Terms WGU D425 · Chemistry
Stoichiometry Immiscible
The calculation of quantities in A solution that has not yet reached its
chemical reactions maximum solubility
Pressure Law of conservation of mass
Also known as Torr, Atm, Mm Hg Matter can neither be created nor
destroyed
Physical changes Heterogeneous mixture
Do not alter the composition of matter Examples include salad dressing, chex
mix, rocks, salad, chicken noodle soup
Oxidizing agent Reducing agents
Are being reduced because they Are being oxidized because they
accept electrons donate electrons
Reduction Electrolyte
The process of gaining electrons A substance that dissociates into ions
in solution
, Unsaturated solution Mixture
A solution that has not yet reached its A combination of two or more
maximum solubility substances that retain their individual
properties
Molar mass of Na How is energy transferred?
The mass of one mole of sodium, potential and kinetic energy, heat and
approximately 22.99 g/mol work
Oxidation What is a product?
gain of protons, increase in oxidation A substance produced in a chemical
number, energy of motion, loss of reaction
electrons
What is the molar mass of H? What degree is a tetrahedral?
1 109
What is the molecular geometry What is dilution?
H2O?
the addition of a solvent to decrease
bent the concentration of a solute in a
solution
What is a decomposition reaction? What is reduction?
When a single compound is broken loss of oxygen or gain of electrons
down into smaller molecules
(AB→A+B)
