What does the kinetic theory state about the kinetic energy of gas molecules? a. the kinetic energy of gas molecules is inversely proportional to the kelvin temperature of the gas. b. the kinetic energy of gas molecules is directly proportional to the kelvin temperature of the gas. c. the kinetic energy of gas molecules is unaffected by the kelvin temperature of the gas. d. the kinetic energy of gas molecules is inversely proportional to the square of the kelvin temperature of the gas. reset next

option B. The kinetic energy of gas molecules is directly proportional to the Kelvin temperature of the gas.

Explanation:

The kinetic theory of gases explains the behavior and properties of gases from a molecular perspective.

Specifically and explicity, the kinetic theory of gases states that gases are constituted by particles (molecules) and that the average kinetic energy of the particles is proportional to the absolute temperature (Kelvin scale) of the gas. Furthermore, the temperature of all the (ideal) gases is the same at a given temperature.

Hence, you know that the higher the temperature of the gas, the higher the kinetic energy and the average speed of the molecules.

Other postulates of the kinetic theory of gases are that: i) the volume of the particles is neglectible; ii) the particles do not exhibit intermolecular attraction or repulsion; iii) the particles are in continuous random motion in straight paths, until they collide with other particles or the walls of the vessel, and iv) the collisions are elastic (the energy is conserved).

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
