The picture shows to containers filled with a gas, both initially at room temperature AAA
Ice
Heat
Which statement is correct? (5 points)
The gas particles in both containers have the same average kinetic energy because they have equal number of particles
The gas particles in both containers have the same average kinetic energy because they have the same volume
The average kinetic energy of the gas particles is greater in container A because it has a lower temperature
The average kinetic energy of the gas particles is greater in container 8 because its particles move faster
Od

D. The average kinetic energy of the gas particles is greater in container B because its particles move faster.

Explanation:

Option D is the correct statement. From the excerpt, it can be seen that container B is being heated. The heat that is applied to container B will make the temperature of the gas to increase, thereby increasing the average kinetic energy. This will cause the gas molecules to mover faster and with force hitting the walls of the gas container. At this time, pressure should increase. Also, the volume of the gas increases just as the temperature of the gas also increases.

first, consult an activity series chart to determine if al is more reactive than fe. it is, so it will replace the fe. now, one can continue with the problem.

next, make sure you have a correctly balanced equation.

3feo + 2al ==> 3fe + al2o3

now, determine which reactant (feo or al) is in limiting supply.

moles feo present = 125 g x 1 mole/71.8 g = 1.74 moles

moles al present = 25.0 g x 1 mole/26.98 g = 0.927 moles

since from the balanced equation, it take 3 mol feo for every 2 mol al, al will be limiting.

you can determine this simply by dividing moles of each by their coefficient in the balanced equation. for example: 1.74/3 = 0.58 and 0.927/2 = 0.464. al is less, so it is limiting.

finally, using the stoichiometry in the balanced eq. determine mass of fe that can be produced from 0.927 moles of al.

0.927 moles al x 3 moles fe/2 moles al x 55.8 g/mole = 77.6 g

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
