Scientists explain some of the properties of matter in terms of the kinetic energy of the particles that make up the substance. The model scientists use is called
the kinetic theory (also called kinetic molecular theory). How do scientists
describe all matter in this theory?
a. All matter is described as tiny particles that are in constant motion
b. All matter is described as gases that are in constant motion
c. All matter is described as tiny particles
d. The Kinetic theory only explains the properties of gases.

please answer asap thank you :))

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
