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 :))

Answer asap need it by wednesday morning carry out the following calculations on ph and ka of from data. i. calculate the ph of 0.02m hcl ii. calculate the ph of 0.036m naoh iii. calculate the ph of 0.36m ca(oh)2 iv. calculate the ph of 0.16m ch3cooh which has ka = 1.74 x 10-5 mol dm-3 v. calculate ka for weak acid ha which has a ph of 3.65 at 0.30m concentration vi. calculate the ka of a solution made by mixing 15.0 cm3 0.2m ha and 60.0 cm3 0.31m a-. [ph= 3.80] vii. calculate the ph of a solution made by mixing 15.0 cm3 0.1m naoh and 35.0 cm3 0.2m hcooh. [ka = 1.82 x 10-4 m]
