How can we describe the molecular motion of states of matter?
The speed of the molecules is reflected by temperature, but their movement follows the following general pattern: Solids have molecules in a relatively fixed position. They vibrate, but don't really move in relation to each other. If there's a rigidly structured pattern, the solid is a crystal. If not, it's amorphous. Liquid molecules can move in relation to each other, and as such have no definite shape. Surface tension exists, and molecules do have attraction to each other, but they can slide across each other. Gases have no definite shape or volume, so molecules move relatively independent of each other, and bonds between molecules don't exist.
Which two physical properties allow a mixture to be separated by chromatography?
Size and shape. However, chemical properties are usually more important.
What two factors of a molecule determine whether or not cross the membrane?
size and shape. cell membranes are selectively permeable, so only some molecules can get through. (i.e. water can go through, but starch cant) Polarity and size.
How does a plasma membrane determine selectivity of molecules?
Plasma membrane possesses specific protein channels and lipid bilayer. Protein channels are of million different types, each allow a specific molecule to pass through it regarding its size, shape, charges on it, solubility, etc. Fat soluble molecules pass through lipid bilayer.
Explain what determines the viscosity of a liquid?
the shape and size of the molecules that the fluid consists of, if they are big, wavy molecules then the liquid will be viscous because the molecules struggle to move over each other.
Why is trigonometry important for chemistry?
Some chemical reactions depend on the shape of molecules and the study of the shape of molecules - requires knowledge of trigonometry.

What affects the shape of molecules?
The chemical compositon and the chemical bonds affect the shape of molecules..
What general shape do molecules have?
The general shape is "bent".

What are the molecules has a bent shape?
Water molecules have a bent shape.

What account for solid matter to be definite in shape while liquid and gas to be indefinite in shape?
because of its molecules solid molecules are very close to each other that's why they make definite shape, while liquid and gas molecules are far apart.
What general shape do water molecules have?
The general shape is "bent".
What shape are dna molecules?
Double helix
