1. A researcher mixed 5.00 ml of 2.03 x 10^-1 M Fe(NO3)3 with100.00mL of 2.05 x 10^-3 M KSCN, using 5.0 x 10^-1 M HNO3 assolvent for both solutions. The resulting measured absorbance forthe solution was 0.315. Based on the data what is [Fe*] (i thinkthis means the total Fe in solution)?
2. Ions B and C react to form BC. If 15.0 mL of 1.00M B is combinedwith 15.0 mL of 1.00M C, .00450 mol BC is formed. Determine the equilibrium constant.

Suppose that the volume of a particular sample of Cl2 gas is 8.7 L at 895 torr and 24 degrees Celsius. How many grams of Cl2 are there in the sample.
IR of Benzpinacol and to what carbon, proton, or functional group (respectively) would each peak belong?
A 486 mL sample of water was cooled from 50.0°C to 10.0°C. Assuming a specific heat of 4.184 J/K g and a density of 1.00 g/mL, find the amount of heat transferred from the water to the surroundings.
