An engineer wants to determine the safety of a car design by conducting 2 points a collision test. During the test, a car is crashed into a solid wall. Then the
engineer measures the force of the collision on the car and compares that
to the damage done to the car. Compare the force of the collision on the
wall with the force of the collision on the car. Use Newton's third law of
motion to support your answer. *

What is the mass of sodium in 3 moles of sodium chloride

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]
