A patient with T10 paraplegia is working with a physical therapist assistant on how to react in the event of a backward fall. The patient is instructed to place one hand behind the head and the other across their lap as seen in the image. This directive will protect the head and:

A physical therapist assistant instructs a patient in a home stretching program that includes the pictured stretch. The MOST likely structure targeted is the:

A student prepares a 2.6 M aqueous solution of benzoic acid, C6H5COOH. What percent of benzoic acid is in the dissociated form in the student’s solution. 

Although a reaction system may be at chemical equilibrium, the rate constants of the forward and reverse reactions will in general be different.

A physical therapist assistant conducts an inservice on exercise guidelines for a group of senior citizens. As part of the inservice the physical therapist assistant discusses the benefits of improving cardiovascular status through a low intensity activity such as a walking program. What frequency of exercise would be the MOST desirable to achieve the stated objective?

When 50.0 mL of 0.25 M methanoic acid, HCOOH, Ka = 1.8 × 10−4 is combined with 50.0 mL of 0.25 M hydrazine, a base, H2NNH2, Kb = 1.3 × 10−6, the resulting solution is:

Consider the following gas phase reaction: A(g) + B(g) ⇌ 2C(g)    Kp = 36 If initially 2.0 atm of A and 2.0 atm of B are placed in a chamber and then the reaction is allowed to proceed, calculate the equilibrium partial pressure of C.

Consider the acid ionization reaction of carbonic acid (H2CO3), which has a Ka of 3.98 × 10─7 H2CO3(aq) + H2O(l) ⇌ HCO3−(aq) + H3O+(aq) Which of the following will decrease the pH of the resulting solution? I. Addition of HCO3− II. Addition of H2CO3 III. Removal of HCO3−  

A chemist dissolves 324.mg of pure barium hydroxide in enough water to make up 90.mL of solution. Calculate the pH of the solution. (The temperature of the solution is 25°C)

Nitrous acid, HNO2, is a weak acid in water (pKa = 3.35). If an aqueous solution of nitrous acid with pH 2.69 is required, what concentration, in M, of the acid is needed? Enter your numerical answer to 4 decimal places and without units.
