The complete combustion of 0.459 g of benzoic acid, C7H6O2 (AH°C= -3230 kJ mol-1) in a bomb
calorimeter causes the temperature to rise by
1.17°C. The complete combustion of 1.705 g of
glucose, C6H12O6 in the same calorimeter causes a
temperature rise of 2.57°C.
Determine the heat capacity of the calorimeter.​

Imagine that you have produced several versions of lactase, each of which differs from normal lactase by a single amino acid. describe a test that could indirectly determine which of the versions significantly alters the three-dimensional shape of the lactase protein.

If i initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 k, and then i raise the pressure to 14 atm and increase the temperature to 300 k, what is the new volume of the gas?

If we compare and contrast electromagnetic waves with sound waves, all but one statement is true. that is a) sound waves require a medium to travel while electromagnetic waves do not. b) electromagnetic waves can travel through the vacuum of space while sound waves cannot. c) electromagnetic waves must have a medium in which to travel, but sound waves can travel anywhere. eliminate d) sound waves must bounce off of matter in order to travel while electromagnetic waves do not require matter to be present.
