How many molecules are there in 218.4 grams of C0CI2?
Alex Ar [27]

Answer:

10.24 ×10²³ molecules

Explanation:

Given data:

Mass of COCl₂ = 218.4 g

Number of molecules = ?

Solution:

Number of moles of COCl₂:

Number of moles = mass/molar mass

Number of moles = 218.4 g/ 129.84 g/mol

Number of moles = 1.7 mol

1 mole contain 6.022×10²³ molecules.

1.7 mol × 6.022×10²³ molecules / 1mol

10.24 ×10²³ molecules

What is evaporation? Describe what happens at the molecular level during evaporation.
jasenka [17]
 Evaporation happens<span> when atoms or </span>molecules<span> escape from the liquid and turn into a vapor. Not all of the </span>molecules in a liquid have the same energy. <span>Sometimes a </span>liquid<span> can be sitting in one place (maybe a puddle) and its molecules will become a </span>gas<span>. That's the process called </span>evaporation<span>. 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 </span>energy<span>. When the energy in specific molecules reaches a certain level, they can have a </span>phase change<span>. 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. </span>

Which Earth motion describes the wobbling of the Earth around its precessional axis and
Alexeev081 [22]

Answer:

Nutation

Explanation:

The counterclockwise rotation of planet earth around its own axis is defined as the Earth Rotation. The earth rotates about the line called "the axis of rotation," it is an imaginary line that passes through the North and South Poles of the planet, which the earth rotates about.

Hence, earth rotates once in about 24 hours with respect to the Sun, from West to East and thus giving rise to;

a. Day and night

b. Seasons

The Earth motion which describes the wobbling of the Earth around its precessional axis and could alter the amount of seasonal effects is known as nutation.

Basically, nutation usually occurs when the precessional motion of a planetary body such as planet earth experience some form of irregularities when it is rotating.
