Explain how to balance the chemical equation and classify its reaction type.
Brrunno [24]

Answer:  The balanced chemical equation is given below.

Explanation:

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

This also means that total mass on the reactant side must be equal to the total mass on the product side.

The balanced chemical equation follows:The balanced chemical equation follows:

On reactant side:

Number of carbon atoms = 10

Number of hydrogen atoms = 10

Number of iron atoms = 1

On product side:

Number of carbon atoms = 10

Number of hydrogen atoms = 10

Number of iron atoms = 1

So, the balanced chemical equation is given above.

The graph shows the distribution of energy in the particles of two gas samples at different temperatures, T1 and T2. A, B, and C
coldgirl [10]

Answer:

  • <u><em>The average speed of gas particles at T</em></u><em><u>₂</u></em><u><em> is lower than the average speed of gas particles at T</em></u><em><u>₁</u></em><u><em>.</em></u>

Explanation:

<em>Particles A and C</em> are shown as if they are on the same vertical line, which means with the same kinetic energy. Both particle A and C are to the lett of <em>particle B</em>, which means that the formers have a lower kinetic energy than the latter.

Since the likelyhood of a particle to participate in the reaction increases with the kinetic energy, particle B is more likely to participate in the reaction than particles A and C. Hence, the first choice is incorrect.

The graph, although not perfectly symmetrical, does show a bell shape, hence there are many particles will low kinetic energy and many particles with high kinetic energy. You cannot assert that most of the particles of the two gases have high high speeds. Hence, second statement is incorrect, too.

At high values of kinetic energy (toward the right of the curve), the line labeled T₁ is higher than the line labeled T₂, meaning that at T₁ more particles have an elevated kinetic energy than the number of particles that have an elevated kinetic energy at T₂.

On the other hand, at low values of kinetic energy (toward the left of the curve) the line T₂ is higher than the line T₁, meaning that at T₂ more particles have a low kinetic energy than the number of particles that have low kinetic energy at T₁.

Hence, the last two paragraphs are telling that the average kinetic energy of gas particles at T₂ is is lower than the average kinetic energy of gas particles at T₁.

Since the average speed is proportional the the square root of the temperature, the same trend for the average kinetic energy is true for the average speed, and you conclude that the last statement is true: "The average speed of gas particles at T₂ is lower than the average speed of gas particles at T₁".

Since more particles at T₁ have high kinetic energy than the number of particles at T₂ that have a high kinetic energy, more particles of gas at T₁ are likely to participate in the reaction  than the gas at T₂, and the third statement is incorrect.

Find the location of flourine (F) on the periodic table what type of ion will fluoring form?
krek1111 [17]

Answer:

VII'th group, negative ion

Explanation:

Usually fluorine is located in the seventh(VII) group as fluorine has 7 electrons in it's outer shell with chemical symbol "F"
Fluorine has 7 electrons in it's outer shell therefore, it needs one more electron to get the noble gas configuration. So more electrons means negative ion.
