Chemistry
2 answers:
stira [4]3 years ago
7 0

Answer:

First line of the table:

FeS: 1.2mol  

O_{2}: 1.8moles

FeO: 1.2moles

SO_{2}: 1.2moles

Second line of the table:

FeS: 5.2mol  

O_{2}: 7.8moles

FeO: 5.2moles

SO_{2}: 5.2moles

Explanation:

1. Take as reference the balanced chemical equation:

_{2}FeS(s)+_{3}O_{2}(g)=_{2}FeO(s)+_{2}SO_{2}(g)

2. Take the first quantity given in the table to calculate the quantities of the other compounds using stoichiometry:

- Calculate the number of moles of O_{2}:

1.2molesFeS*\frac{3molesO_{2}}{2molesFeS}=1.8molesO_{2}

- Calculate the number of moles of FeO:

1.2molesFeS*\frac{2molesFeO}{2molesFeS}=1.2molesFeO

-Calculate the number of moles of SO_{2}:

1.2molesFeS*\frac{2molesSO_{2}}{2molesFeS}=1.2molesSO_{2}

3. Take the second quantity given in the table to complete the other quantities using stoichiometry:

- Calculate the number of moles of FeS:

5.2molesSO_{2}*\frac{2molesFeS}{2molesSO_{2}}=5.2molesFeS

- Calculate the number of moles of O_{2}:

5.2molesSO_{2}*\frac{3molesO_{2}}{2molesSO_{2}}=7.8molesO_{2}

- Calculate the number of moles of FeO:

5.2molesSO_{2}*\frac{2molesFeO}{2molesSO_{2}}=5.2molesFeO

For 1.2 mol FeS, 1.8 mol O2, 1.2 mol FeO, 1.2 mol SO2
For 5.2 mol SO2, 5.2 mol FeS, 7.8 mol O2, 5.2 mol FeO

Name the phase change in each of these events: (c) Wet clothes dry on a summer day
8090 [49]

The phase change occurs during evaporation. On a hot day, wet clothing is drying. A liquid becomes a gas when it evaporations.

During the process of evaporation, a liquid transforms into a gaseous phase that is not saturated with the evaporating substance. The term "vaporization of a liquid" refers to this process. Clothes start to dry as water vapor escapes from the fabric's surface.

<h3>What is evaporation?</h3>

A liquid turns into a gas through the process of evaporation. Raindrops that "vanish" on a hot day or damp clothing that dries in the sun are good examples of the phenomena. In these instances, the liquid water is evaporating into a gas known as water vapor rather than really dissipating. Global evaporation takes place.

Which of the following correctly describes what happens to the kinetic energy of water when it changes from steam to a liquid?
IgorLugansk [536]

Answer:

kinetic energy decreases

Explanation:

kinetic energy usually increases when hot and decreases when cold. The steam is turning into a liquid because it is cooling down, causing the molecules to move less and slow down.
