2. A thermodynamic process that maintains a constant volume is called an isochoric process. During these types of processes, the gas does no work because it is not increasing the volume of the container. If you sealed off the top of a water bottle and shook 100 mL of water for two minutes, you would find that the

If you sealed the lid of a water bottle and stirred 100 mL of water for two minutes, you would find that the water got hotter.

Explanation:

If you cap a bottle that contains 100 mL of water and shake the bottle, you will cause the water molecules to move. This will cause them to bump into each other, releasing energy that will increase the temperature of the system and heat water. This is because the potential energy stored in the water molecules was transformed into kinetic energy with the movement of these molecules, which, again, was transformed into thermal energy.

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8
