In Class Question 4.6 (From Simulation) A box is at rest on a horizontal surface. Suppose we apply a horizontal pushing force to the box and the box doesn't move. How do the frictional force and applied force compare? Consider this student's response: The frictional force on the box will equal the pushing force, because according to Newton's third law, for every action there is an equal but opposite reaction. Do you agree with the student? A. Yes, the student's answer and explanation are correct. B. No. The student correctly states that friction equals the pushing force, but the explanation is wrong. C. No. Friction is greater than the pushing force. D. No. Friction is less than the pushing force.

A buffer solution is creating by mixing equal amounts of aqeuous CH3COOH and NaCH3COO. The strong base LiOH is then added to the buffer. Which of the following represents the reaction of the strong base with the buffer solution (do not include spectator ions)? H2O + CH3COO- → OH- + CH3COOH OH- + CH3COOH → H2O + CH3COO- OH- + CH3COO- → H2O + CH3COOH H2O + CH3COOH → OH- + CH3COO- LiOH → Li+ + OH-
