The deltaH for the solution process when solid sodium hydroxide dissolves in water is 44.4 kJ/mol. When a 13.9g sample of NaOH dissolves in 250.0 g of water in a coffee-cup calorimeter, the temperature increases from 23.0°C to ? . Assume that the solution has the same specific heat as liquid water, i.e., 4.18 J/g-K.

Congratulations! You have just been hired as a researcher by the PRUB Chemical Company Because of the large number of people eating spicy foods (and often eating them too fast), this company has asked you to develop a new antacid. They have given you some information, but the rest you must discover for yourself. Your boss has suggested that aluminum hydroxide may be effective as an antacid. This...

A piece of solid aluminum weighing 39.4 g at a temperature of 586 °C is placed in 394 g of liquid aluminum at a temperature of 663 °C. After a while, the solid melts and a completely liquid sample remains. Calculate the temperature after thermal equilibrium is reached, assuming no heat loss to the surroundings....

Matlab While loop help I'm doing a random walk problem and i need to make it so that when the walker goes over a certain position it gets reflected back onto the center (position=0). For this I'm trying to use while loops but they seem to get stuck. The program works fine until it reaches one of its limits (-10 or 10) then the while loops are supposed to prevent the position from going further and instead send the position...
