Question

b) in the presence of a facilitated transporter protein specific to sodium ion. c) in the presence of an ATPase pump. You are asked to prepare a 240 mL of a 3% morphine sulfate solution. You have four S0-ml vials of morphine labeled as 50 mg/ml. Do you have enough stock solution? How will you prepare the aqueous solution? 6) 7) What are the products of the following reaction: cacofs) + 2HCl(aq) Cacilaq + 8) List attractive forces (all possible forces) found in each of the pure substances below: b. a. Na,CO C. CH3 H3C f. OH HO OH OH OH

Explanation / Answer

Q7.

CaCO3(s) + 2Hcl(aq) = CaCl2(aq) + X + Y

note that:

X = CO2(g) due to CO3- presence

Y = H2O(l), due to the hydratoin of H2CO3 cabronic acid

so

CaCO3(s) + 2HCl(aq) = CaCl2(aq) + CO2(g) + H2O(l)
