In an experiment, the data collected can be qualitative
In an experiment, the data can also be quantitative
-
A dependent variable is a part of qualitative data because it's the output generated by the dependent variable.
After the hypothesis is proven with an experiment multiple times, it becomes a theory.
An independent variable is a part of qualitative data collected, since it also affects quantitative data.

If one element changes the number of neutrons, it's mass changes, so does it's isotope.

Pure substances have mass and take up space, so they are considered matter.
Mixtures are matter because they take up space and have mass. They are a combination between multiple elements and compounds, thus making them not a pure substance.
Compounds can be pure substances because they can be a chemical combination between 2 of the same elements.
-
A property of an atom can be chemical, for example electronegativity.
-
When chemical reactions happen, the chemical energy in compounds change.
In endothermic and exothermic reactions, the reactants and chemical energy are needed.
When activation energy is applied to reactants, a chemical reaction occurs
When the chemical reaction is finished, the product is created.

Individual atoms, they are pure substances because they are not made of anything but the single atoms that make them up.
-

-
Every atom has a nucleus, a dense part of the atom where most of it's mass comes from.

A form of filtration, done by measuring their affinity, or attraction, to the mixture.
-
In a homogeneous mixture to form a solution, there's always a solute added to the solvent.
-
If a substance is insoluble, it can't be dissolved, thus, the solubility is at 0%.
If a substance is soluble, then it's able to be dissolved. Making a solution.
When a solution cannot add more solute, it then becomes saturated.
When a saturated solution has more solute added to it, the solution becomes supersaturated.
In a homogeneous mixture, to form a solution, there's always a solvent, where the solute dissolves in.
