How many moles of PC15 can be produced from 51.0 g of Cl2 (and excess P4)?
slava [35]

Answer:

0.287 mole of PCl5.

Explanation:

We'll begin by calculating the number of mole in 51g of Cl2. This is illustrated below:

Molar mass of Cl2 = 2 x 35.5 = 71g/mol

Mass of Cl2 = 51g

Number of mole of Cl2 =..?

Mole = Mass /Molar Mass

Number of mole of Cl2 = 51/71 = 0.718 mole

Next, we shall write the balanced equation for the reaction. This is given below:

P4 + 10Cl2 → 4PCl5

Finally, we determine the number of mole of PCl5 produced from the reaction as follow:

From the balanced equation above,

10 moles of Cl2 reacted to produce 4 moles of PCl5.

Therefore, 0.718 mole of Cl2 will react to produce = (0.718 x 4)/10 = 0.287 mole of PCl5.

Therefore, 0.287 mole of PCl5 is produced from the reaction.

Question 1 (2 points)
natulia [17]

Temperature is the average kinetic energy of gas molecules.

<h3>What is absolute zero?</h3>

The term absolute zero refers to the hypothetical point where the energy of molecules is zero. It is the point where all of their motion stops completely.

In a liquid, the movement of the molecules is more significant than in a solid. If you keep increasing the temperature of a liquid, it will boil and become a gas.

Matter contains energy which depends on the temperature of matter. To remove the energy of matter, you have to lowering its temperature.

The addition of energy to matter occurs when matter is heated. Hence, you add energy to matter by heating it.

The molecules at warm temperatures differ from the molecules at cool temperatures because the molecules at warmer temperatures move around more.

The air on a hot day compares to the air on a cool day in the sense that on a hot day, air molecules have more energy.

Temperature is depends on the kinetic energy of molecules. Hence, the best description of temperature is motion of molecules.

The temperature of a body is the average kinetic energy of its molecules.  When two things that are not touching have the same temperature their molecules move at the same average speed.

Since a liquid receives energy when it is heated, when the liquid is boiled beyond its boiling point, It will become a gas.

The difference between heat and temperature is that temperature measures the motion of molecules, and heat is the energy of that motion.

What is the most likely result of the pollution of a fresh water resource?
Troyanec [42]

Answer:

Loss of biodiversity in the wetlands.

Explanation: Pollution can be defined as the emission of toxic, poisonous and harmful chemical substances which are capable of causing environmental degradation and contamination.

Nitrogen pollution enters Earth’s freshwater resources from a variety of human activities, including the use of fertilizers and pesticides in agriculture. This nitrogen pollution has a negative effect on plants and animals living in fresh water. Certain wetland plants, however, are able to purify the water and restore it to its non-polluted state.

Hence, what would most likely increase the negative effects of nitrogen pollution is a loss of biodiversity in the wetlands i.e the various species of animal and plants.
