How do you determine the volume flow rate
Water with a static pressure of 1.96kN/M2 flows through an 800 mm diameter pipe. A pitot tube pressure gage in this pipe reads a pressure of 5.88 kN/M2. How do you determine the volume flow rate (Q) of the water? (Q = 1.40 M^3/sec, V=2.79 M/sec)

A 0.12M solution of a weak acid HA has pH = 2.49. What is the Ka of this acid?
if 25.00 cm3 of 0.1000M NaCl is mixed with 25.00 cm3 of 0.1000M AgNO3, what is the concentration of Ag+ remaining in solution? Is this sufficient to precipitate any silver chromate?
A student mixes 5.00 mL 2.00 x 10-3 M Fe(NO3)3, 2.50 mL 2.00 x 10-3 M KSCN, and 2.50 mL H2O to give a solution having a total volume of 10.00 mL. She finds that in the equilibrium mixture the concentration of FeSCN2+ is 7.50 x 10-5 M. What is the
