A fixed shape. gasses do not have a definite volume (which stems from lack of definite shape) which is why their volume is the same as the container they are being held in.

Answer: Option (b) is the correct answer.

Explanation:

Dry ice is the solid form of carbon dioxide whereas carbon dioxide gas present in the atmosphere is present in gaseous phase.

Also it is known that in solids, particles are held together tightly due to strong intermolecular forces of attraction. As a result, solid substances have fixed shape and volume.

On the other hand, in gases particles are held by weak intermolecular forces due to which they are far apart from each other. As a result, they do not hace any fixed shape.

Hence, we can conclude that frozen $CO_2$ or dry ice is different from $CO_2$ gas in the atmosphere because it has a fixed shape.

A sample of SO2 gas occupies 45.6 L at 373 K and 3.45 atm. This sample contains how many moles of oxygen atoms?

lisov135 [29]

Answer:

10.28 mol

Explanation:

S + 2O = SO2

(atm x L) ÷ (0.0821 x K)

(3.45 x 45.6) ÷ (0.0821 x 373)

=5.13726

Then round it to significant figures

=5.14

5.14 mol SO2 x (2 mol O ÷ 1 mol SO2)

=10.28 mol O

What is evaporation? Describe what happens at the molecular level during evaporation.

jasenka [17]

Evaporation happens when atoms or molecules escape from the liquid and turn into a vapor. Not all of the molecules in a liquid have the same energy. Sometimes a liquid can be sitting in one place (maybe a puddle) and its molecules will become a gas. That's the process called evaporation. It can happen when liquids are cold or when they are warm. It happens more often with warmer liquids. You probably remember that when matter has a higher temperature, the molecules have a higher energy. When the energy in specific molecules reaches a certain level, they can have a phase change. Evaporation is all about the energy in individual molecules, not about the average energy of a system. The average energy can be low and the evaporation still continues.
