Matter
What is filtration?
Separates mixtures made up of solids and liquids, solids stop in the filtration paper.
What is deposition?
A gas changes directly to a solid.
What are orbitals?
The probable location electrons around the nucleus?
Is Hydrogen a metal or nonmetal?
Nonmetal.
What is solution?
A homogeneous mixture of two or more substances, typically composed of a solute dissolved in a major component solvent.
What is Distillation?
The process of separating substances in a mixture by their boiling point.
What is Sublimation?
Substance that go from a solid directly to a gas (ex: carbon dioxide).
The distribution of electrons. The outermost electrons are the valence electrons.
What is the most reactive nonmetal?
What does unsaturated mean?
An unsaturated solution is able to dissolve more solute.
What is a element?
A substance that cannot be broken down by chemical means (decomposed).
What is system of Nature?
Tend to go towards high entropy, low energy.
What was the Cathode ray tube?
What is the most reactive metal?
Francium.
What does supersaturated mean?
An unstable state containing more dissolved solute than the maximum amount capable of being dissolved at a given temperature.
What is a chemical change?
A change in the chemistry of a molecule, turns into something different examples, burning/reacting.
What is entropy?
A measure of randomness or disorder.
When an electron releases energy as it moves from a higher to lower principal energy level.
It is being drawn into wire.
What is solute?
A substance that dissolves in a solvent to form a homogeneous mixture known as a solution.
What is Chromatography?
Physical separation technique that works due to difference in solubility based on polarity.
What is endothermic reactions?
Absorbs energy and the energy is a reactant in the reactions.
What is rutherford's gold foil experiment?
Showed that an atom is mostly empty space with a small, dense, positively charged nucleus.
What is malleable mean?
Capable of being easily shaped or hammered.
What is solvent?
A substance usually a liquid that dissolves a solute (a solid, liquid, or gas) to form a homogeneous mixture known as a solution.
