The average distance a gas particle travels between collisions (with the wall or another particle is called the mean free path.

According to the kinetic theory of gases, the particles of a gas (atoms or molecules) have the highest kinetic energy and travel at high speeds. At standard temperature and pressure, a gas particle can reach speeds of about 470m/s.

Despite the high speeds gas particles travel, it still takes a while for the fragrance of an opened perfume to diffuse to the other end of the room. This is because when moving, the molecules do not have a free path. They constantly collide with other particles and the walls of the container and change direction randomly. The average distance a single particle can travel without colliding with other particles, or the wall of the container is called the mean free path.

A compound is composed of 85.6% Carbon and the rest is Hydrogen. The molecular mass of the compound is 42.078g/mol. What is the

s344n2d4d5 [400]

The molecular formula for the compound is $C_{3} H_{6}$

<u>Explanation</u>:

As with all of these problems, we assume 100 g of an unknown compound.

And thus, we determine the elemental composition by the given percentages.

Moles of carbon = 85.64 / 12.011

= 7.13 mol.

Moles of hydrogen = 14.36 / 1.00794

= 14.25 mol.

There are 2 moles of hydrogen per mole of carbon. And thus the empirical formula is CH $_{2}$ .

And molecular formula = n × (empirical formula)

Thus, 42.08 = n × (12.011 + 2 × 1.00794)

And thus n = 3, and molecular formula = $C_{3} H_{6}$

What is Equilibrium? I’m a little confused on the topic. You’ll get a lot of points if you answer I think.

AleksAgata [21]

Answer:

to put it simply, equilibrium is when two opposing forces balance each other out. one example is boats: you know how the bottom half is curved, and then meets at an edge? they design it like that because of water displacement. by gravity, the water wants to go back to the area taken by the boats mass (the parts where it has sunken into the water), thus preventing the boat from sinking. once the boat is removed, the water returns to the space. most liquids take form of their container.
