Answer:
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. The scientific study of crystals and crystal formation is known as crystallography.
Explanation:
Higher concentrations of reactants = More collisions between molecules = More possible reactions between the molecules = Higher reaction rate
<h3>What is concentration?</h3>
A solution is made up of two components, solute and solvent. In chemistry, we define the concentration of solution as the amount of solute dissolved in the solution.
Increasing the concentration of reactants generally increases the rate of reaction because more of the reacting molecules or ions are present to form the reaction products. This is especially true when concentrations are low and few molecules or ions are reacting.
Hence, Higher concentrations of reactants = More collisions between molecules = More possible reactions between the molecules = Higher reaction rate.

Answer:
C. freezing
Explanation:
Point B is right at the border between a solid and a liquid so you can have two physical changes:
a) solid is <u>meting</u> to transform into a liquid
or
b) liquid is <u>freezing</u> to transform into a solid (C)
If you are on the border between a solid and a gas you have the following physical changes:
solid to gas - sublimation
gas to solid - deposition
If you are on the border between a liquid and a gas you have the following physical changes:
liquid to gas - boiling
gas to liquid - condensation
