Two kg of water at a temperature of 50 degrees C have 485.3 kJ of heat transferred from them, resulting in a mixture of ice/water at 0 degrees C. What is the composition of the mixture? This is what I did and would like verification of my answer. 2*4.183*-50 = -418.3 kJ I then...
A quantity of water at 87 degrees C is cooled at a rate of 2844 MJ/h. After 40 minutes, the water has changed to ice, having a temperature of 243K. Calculate the mass of the water/ice. I know 243K = -30 degrees C I'm assuming I have to use my sensible and latent heat formu...
If 55034.175 kJ of heat are transferred to 150 kg of ice at a temperature of -12.15 degrees C, calculate the temperature of the resulting water. I know my formulas for sensible and latent heat but don't know how to approach this.
For some positive constant C, a patient's temperature change, T , due to a dose,D , of a drug is given by T=(c/2-D/3)D^2 What dosage maximizes the temperature change The sensitivity of the body to the drug is defined as . What dosage maximizes sensitivity?
Find constants a and b in the function f(x)=axe^(bX) such that f(1/8)=1 and the function has a local maximum at x=1/8.
A boat is pulled through a canal by horses walking parallel to the canal and exerting a force of 1000 N on a tow rope 40 meters long. If the distance from the boat to the horse track is 15 meters, what is the magnitude of the effective component pulling the boat forward?

A compound of Tin Sulfate is decomposed in the lab to give 1.91g of Tin, 1.03 grams of Sulfur, and 2.06g Oxygen. Determine if this is a compound of Tin(II) Sulfate or Tin(IV) Sulfate.
A person standing at the edge of a seaside cliﬀ kicks a stone over the edge with a speed of 21 m/s. The cliﬀ is 52 m above the waters surface. How long does it take for the stone to fall to the water? The acceleration of gravity is 9.81 m/s^2. Thanks!
Ahh makes much more sense when Reiny did it. I remember learning this in algebra. I have a tendency to give everything its own variable, which makes the problem impossible to solve i guess.
