Explanation:

As molecules in a solid substance are placed closer to each other because of existence of strong forces of attraction. So, these molecules are unable to move randomly but they are able to vibrate at their mean position.

Hence, molecules of a solid have low energy.

In gases, molecules are held by weak intermolecular forces. So, they are able to move randomly from one place to another. Hence, they have high kinetic energy.According to Kinetic Molecular Theory, molecules of a gas are always in constant motion and they tend to exhibit a perfect elastic collision.

This means that in kinetic molecular theory molecules of a gas are in rapid, random motion.

Boyle's Law states that pressure is inversely proportional to the volume of the gas at constant temperature and number of moles.

$P\propto \frac{1}{V}$ (at constant temperature and number of moles)

Charles' Law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

$V\propto T$ (at constant pressure and number of moles)

Thus, we can conclude that the given items are matched as follows.

1. gas - continuously in motion.

2. solid matter - low energy.

3. Kinetic Molecular Theory - rapid, random motion.

4. Boyle's Law - relates pressure and volume.

5. Charles's Law - relates volume and temperature.

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.
