please help don't get it at all???

Question

how are each word related and how are each word different.?

a) filtrate and residue
b) solvent and solute
c) heterogeneous and homogeneous
d) atom and molecule
e) element and compound
f) atom and ion
g) distillation and evaporation
h) qualitative and quantitative

Answer 1

c) they are both mixtures, homogeneous looks the sames throughout, heterogeneous has different layers with noticable differences in layers.

Answer 2

You filtrate out residue.

A solvent disloves something and a solute gets disolved in something. For instance water is a solvent and the sugar or salt poured into the water is the solute.

Heterogeneous means different and homogeneous means alike. Apes and humans are homogeneous. A rock and a plant would be heterogeneous.

Atoms make up molecules.

Elements make up compounds.

An ion is an electrically charged atom.

Evaporation is the first step in distillation. Distillation also requires the cooling of the air to get the liquid back. Since solids don't evaporate, distillation is a way to seperate solids from liquids. That's one way to get drinking water from salt water for example.

Qualitative is the measure of quality such as the purity level of gold in a piece of jewlery while quantitive is the measure of how many as in how many pieces of jewlery there are.

Answer 3

d) an atom is the basic building block of matter, whereby a molecule is a collection of one or more atoms that combine to form a pure substance.

H2O is a molecule of water, but it is comprised of three atoms.

O2 is a molecule of oxygen, comprised of 2 oxygen atoms.

e) elements are the most basic types of matter. Each element is defined by the number of protons it has. Oxygen is an element. A compound has at least two elements. H2O is a compound. It contains Hydrogen and Oxygen.
