Determine the latent heat of fusion of ethyl alcohol using the following calorimeter data: 50.0 grams of solid ethyl alcohol at its melting point of -114oC is placed in a 350 gram aluminum calorimeter with 400 grams of water at 20.0oC; the resulting equilibrium temperature is 9.82oC. The specific heat of ethyl alcohol is 2.40 k J kg*C. The specific heat of aluminum is 900 J kg*C.

Calculate the percent yield of salicylic acid (from 1.00 mmol isolated) from 7.00 g of Ben-Gay ointment. Ben-Gay ointment is 16% menthol
Calculate the pH of a solution that is formed when 25.0 mL of 0.24 M ammonia (Kb = 1.8 x 10-5) is mixed with 25.0 mL of 0.20 M ammonium chloride.
The Ksp of AgCl at 25 oC is 1.6 x 10-10. Consider a solution that is 1.0 x 10-4 M NaCl and 1.0 x 10-6 M AgNO3. 1. The solution is saturated.
A blank is typically chosen to represent a zero or bseline absorbance reading. the blank itself does not need to have a zero absorbance reading before calibration, and this trait is often used to remove impurities and any stray signals that would ..
