One of the problems with the commercially available bomb calorimeters is that they can test only small samples on the order of a few grams.
Design a bomb calorimeter large enough to burn a sample as large as 1 pound. Pay special attention to safety considerations in your design. Do not attempt to construct or test your design.
A chemist dissolves 128 mg of pure hydrobromic acid in enough water to make up of 110 mL solution. Calculate the pH of the solution.
A pt has a blood Ca level of 4.6 mEq/L If 1mol Ca2+= Eq Ca2+ what is the blood calcium levle in mg/dl
Explain what is the mole fraction of solute and the molal concentration for an aqueous solution that is 10.0% NaOH by mass
What are the equilibrium concentrations of NH2OH (hydroxylamine), NH3OH+, and OH- in a 0.15 M solution of hydroxylamine (Kb=6.6*10^-9)? What is the pH of the solution
A 1.50 g sample of solid NH4NO3 was added to 35.0 mL of water in a styrofoam cup (insulated from the environment) and stirred until it dissolved. The temperature of the solution dropped form 22.7 C to 19.4 C. What is the heat of reaction for disso..
