A patient demonstrates the inability to actively extend the PIP and DIP joints of the index through little fingers of the left hand. The OT would accurately document a potential deficit with which peripheral nerve (s)? 

A laceration of the extensor mechanism at the DIP joint would require which of the following splinting techniques? 

A 1 M solution of NaCl (formula weight = 40.0 g/mol) has a volume of 1 liter. What mass of NaCl is dissolved in the solution?

For the reaction H2(g) + I2(g) ⇌ 2HI(g), Kc = 50 at a certain temperature. If the equilibrium concentrations are [H2] = 0.1 M and [I2] = 0.1 M, what is the equilibrium concentration of HI?

Which concentration unit is temperature-dependent because the volume of the solution can change with temperature?

What is the pH of a solution with a pOH of 9.0?

For the reaction CO(g) + H2O(g) ⇌ CO2(g) + H2(g), Kc = 1 at a certain temperature. If the initial concentrations are [CO] = 2 M and [H2O] = 2 M, what will be the equilibrium concentration of CO2?

What is the molality of a solution containing 3 moles of urea (formula weight = 60 g/mol) dissolved in 1 kg of water?
