Which container has gas stored at the highest temperature?

answer:

the correct answer is:

3 · large number of collisions with container walls · high average kinetic energy · large number of particles with large spaces between them

in fact, the temperature of a gas is directly proportional to the average kinetic energy of its particles, according to the relationship

where ek is the average kinetic energy of the particles, k is the boltzmann's constant, and t is the absolute temperature of the gas. therefore, the higher the kinetic energy, the higher the temperature. option 3) is the one where the particles have higher kinetic energy, therefore it is the gas with highest temperature.

"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  

mgco3-5h2o"
