Answer: (a) Neon, Nitrogen; (b) Neon, Nitrogen; (c) Neon is lower than Nitrogen; (d) It doesn't affect;
Explanation: The kinetic-molecular theory studies the behavior of particles under pre-determinated situation. In cases of gases, the particles moving around colliding with each other and the walls of the container, without loss of energy. In the case in question, all the parameters are the same (same temperature, volume and pressure), except for the gases, which has different molar masses. In this sense, Neon has lower average speed due to its molar mass being higher, which means, its particles moves slower for being heavier. Related to pressure, as velocity is lower, it collides less with the walls of the tank, and so pressure is lower. For density, it doesn't affect the behavior of the system nor the kinetic energy.
Hormones ! hope i helped :)
Hello!
1) What is the limiting reactant?The chemical equation for this reaction is:
2Al(OH)₃ → Al₂O₃ + 3H₂OThe
Limiting Reactant is the one that is in the lowest amount in the reaction and determines how many moles are produced. You can see that in this chemical equation there is only one reactant since this reaction is a
decomposition reaction. So,
the limiting reactant is Al(OH)₃.2) How many grams of water are produced?The chemical equation for this reaction is:
2Al(OH)₃ → Al₂O₃ + 3H₂O
So, we are going to use the following conversion factor to go from grams of Al(OH)₃ to grams of water:
So,
6,17 grams of Water are produced.
Have a nice day!
C, A, A, B, D. Hope this is correct! Have an awesome day!
