Explanation:

The conversion of the liquid to the vapor below boiling temperature of liquid is called evaporation.

Each molecule in liquid phase is attracted to other molecules in liquid by the intermolcular forces of attraction. When the process of evaporation starts, the molecules has to change the phase from the liquid to vapor for which they have to break all these interaction so that they can escape. The molecules with sufficient energy to do so only can do this. These molecules with high energy leave and remaining molecules are ones which did not have the enough energy to evaporate. Thus, average kinetic energy of molecules in liquid left behind is lower than it was before. <u>So, evaporation is a cooling process because heat of the molecules was used up for breaking hotter molecules out into gas phase and the left ones are cooled. </u>

Hello!

The part of the carbon cycle where humans had the greatest impact is the return of CO₂ to the atmosphere by burning of ancient organic matter.

The ancient organic matter is also called Fossil Fuels. Some Fossil Fuels are Petroleum and Coal. Fossil Fuels are used to power our society and are burned to provide energy for power plants and vehicles, and by burning them, Carbon Dioxide (CO₂) is produced, increasing the natural concentration of this compound in the atmosphere.

Answer:

Fe₃Si₇

Explanation:

In order to determine the empirical formula, we have to follow a series of steps.

Step 1: Determine the percent composition

Fe: 46.01%

Si: 53.99%

Step 2: Divide each percentage by the atomic mass of the element

Fe: 46.01/55.85 = 0.8238

Si: 53.99/28.09 = 1.922

Step 3: Divide all the numbers by the smallest one

Fe: 0.8238/0.8238 = 1

Si: 1.922/0.8238 = 2.33

Step 4: Multiply by numbers that make the coefficients whole.

Fe: 1 × 3 = 3

Si: 2.33 × 3 = 7

The empirical formula is Fe₃Si₇.
