🤩 || Chemistry basic important terms and their definition
redox reaction: A reaction that has both an oxidation and reduction.
lattice energy: The energy released when one mole of a crystal is formed
from gaseous ions.
equivalence point: The point in a titration at which the solution is completely neutral. This is different from the "endpoint"
endothermic: When a process absorbs energy (gets cold)
half-life: The time required for half of the radioactive atoms in a sample to decay. When talking about chemical reactions, it's the amount of time required to make half the reagent react.
normal boiling point: The boiling point of a substance at 1.00 atm.
shielding effect: The outer electrons aren't pulled very tightly by the nucleus because the inner electrons repel them. This repulsion is called the shielding effect.
vapor pressure: The pressure of a substance that's present above it's liquid. For example, you can tell that ammonia has a high vapor pressure because the smell of it is very strong above liquid ammonia.
Charles's Law: The volume of a gas at constant pressure is directly proportional to the temperature. In other words, if you heat something up, it gets big.
Hess's Law: The enthalpy change for a change is the same whether it takes place in one big step or in many small.
