Answer:

Fermentation, chemical process by which molecules such as glucose are broken down anaerobically. More broadly, fermentation is the foaming that occurs during the manufacture of wine and beer, a process at least 10,000 years old. The frothing results from the evolution of carbon dioxide gas, though this was not recognized until the 17th century.

The statement is true  about the rotational period of the moon " the rotational period of the moon is equal to the revolution period around Earth."

A celestial object's rotation period may relate towards its sidereal rotation period, which is the time it takes for the object to complete one revolution around in its axis of rotation in sidereal seems like to the background stars.

The orbital period is also known as the revolution period. it takes for one astronomical object to complete one cycle around another. It refers to planets and asteroids orbiting the Sun, moons orbiting planets, planetary systems orbiting other stars, or double stars in astronomy.

In the night sky, the moon is just the brightest object. The moon doesn't at all produce its own light. It has no radiance. That is visible because the sun's light bounces off of it.

The rotational period of the moon is equal to the revolution period around Earth because the moon's rate of spin becomes tidally locked to its rate of revolution, it maintains the same face oriented towards the Earth In other words, every time the moon rounds the Earth, it rotates exactly once.

Therefore, the rotational period of the moon is equal to the revolution period around Earth will be correct answer.

I think that the answer is protons

Answer: The balanced equation is [tex]2FeCl_{3} + 3MgO \rightarrow Fe_{2}O_{3} + 3MgCl_{2}[/tex]

Explanation:

The given reaction equation is as follows.

[tex]FeCl_{3} + MgO \rightarrow Fe_{2}O_{3} + MgCl_{2}[/tex]

Here, number of atoms present on reactant side are as follows.

Number of atoms on product side are as follows.

To balance this equation, multiply [tex]FeCl_{3}[/tex] by 2 and MgO by 3 on reactant side. Also, multiply [tex]MgCl_{2}[/tex] by 3 on product side. Therefore, the equation can be rewritten as follows.

[tex]2FeCl_{3} + 3MgO \rightarrow Fe_{2}O_{3} + 3MgCl_{2}[/tex]

Hence, number of atoms on reactant side are as follows.

Number of atoms on product side are as follows.

Since, this equation contains same number of atoms on both reactant and product side. Therefore, this equation is now balanced equation.

Thus, we can conclude that the balanced equation is [tex]2FeCl_{3} + 3MgO \rightarrow Fe_{2}O_{3} + 3MgCl_{2}[/tex].

Answer:

Condensation

Explanation:

the process of evaporation and condensation takes 7.5 times as much energy as melting or freezing.

According to the forces of attraction, condensation process  requires more energy to be released,as in the process state is changing from less orderly state to a more orderly state.

Forces of attraction  is a force by which atoms in a molecule  combine. it is basically an attractive force in nature.  It can act between an ion  and an atom as well.It varies for different states  of matter that is solids, liquids and gases.

The forces of attraction are maximum in solids as  the molecules present in solid are tightly held while it is minimum in gases  as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.

The physical properties such as melting point, boiling point, density  are all dependent on forces of attraction which exists in the substances.

Answer: When maganese dioxide is added to hydrogen chloride you get water maganese dichloride and chlorine gas then balanced equation is [tex]MnO_{2} + 4HCl \rightarrow 2H_{2}O + MnCl_{2} + Cl_{2}[/tex].

Explanation:

The word equation is given as maganese dioxide is added to hydrogen chloride you get water maganese dichloride and chlorine gas.

Now, in terms of chemical formulae this reaction equation will be as follows.

[tex]MnO_{2} + HCl \rightarrow H_{2}O + MnCl_{2} + Cl_{2}[/tex]

Here, number of atoms on reactant side are as follows.

Number of atoms on product side are as follows.

To balance this equation, multiply HCl by 4 on reactant side and multiply [tex]H_{2}O[/tex] by 2 on product side. Therefore, the equation can be rewritten as follows.

[tex]MnO_{2} + 4HCl \rightarrow 2H_{2}O + MnCl_{2} + Cl_{2}[/tex]

Hence, number of atoms on reactant side are as follows.

Number of atoms on product side are as follows.

Since, this equation contains same number of atoms on both reactant and product side. Therefore, this equation is now balanced equation.

Thus, we can conclude that when maganese dioxide is added to hydrogen chloride you get water maganese dichloride and chlorine gas then balanced equation is [tex]MnO_{2} + 4HCl \rightarrow 2H_{2}O + MnCl_{2} + Cl_{2}[/tex].

Answer:

Chlorine gas is produced

Explanation:

One of the methods of laboratory preparation of chlorine gas is to heat manganese dioxide with concentrated hydrochloric acid. The acid is oxidized by the manganese dioxide to liberate chlorine gas as follows;

MnO2(s) + 4HCl(aq) -------> MnCl2(aq) + 2H2O(l) + Cl2(g)

Hence, When manganese dioxide is heated with concentrated hydrochloric

acid, chlorine gas is liberated.

Explanation:

Plants get energy from sunlight to produce carbohydrates. When a consumer such as herbivore consume plants, he gets energy and when a canivore or omnivore consume the primary consumer, energy is also transfered to them and this is called food chain.

Matter from the environment which include fallen leaves or trees will decompose after a while in the ground when decomposers begin to act on it and it will eventually give them energy. Decomposer help break down organic matter such as leaves,dead animals and get little amount of of energy in the energy flow pyramid

Answer:

The oxidation state of carbon in CaC204 is 3

Answer:The oxidation number of the carbons + the oxidation numbers of the oxygens must equal -2. Carbons + (-8) = -2 so the oxidation number of the carbons must be +6. Since there are 2 carbon atoms each must contribute +3 each. What is the oxidation number of S in Na2S2O3?

Explanation:

The oxidation state of Oxygen is -2 and that of Calcium is +2. There are four oxygen atoms which amounts to -8 charge. This leaves a charge of +6 on Carbon
