Answer: The statement, chemicals that you begin with found on the left side of the equation, describes reactant and where they are in a chemical equation.
Explanation:
An equation that includes symbolic formulas and represents chemical reaction between the substances initially present forming new substances is called a chemical equation.
For example, [tex]N_{2} + 3H_{2} \rightarrow 2NH_{3}[/tex]
Here, substances [tex]N_{2}[/tex] and [tex]H_{2}[/tex] are the reactants. Reactants in a chemical equation are always present on the left side as these are the chemicals we begin with.
Also here, [tex]NH_{3}[/tex] is the product. Product(s) in a chemical equation are always present on the right side as these are the chemicals we end with.
Thus, we can conclude that the statement, chemicals that you begin with found on the left side of the equation, describes reactant and where they are in a chemical equation.

When maganese dioxide is added to hydrogen chloride you get water maganese dichloride and chlorine gas write the balanved equation
Answers
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.
Mn = 1O = 2H = 1Cl = 1Number of atoms on product side are as follows.
Mn = 1O = 1H = 2Cl = 4To 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.
Mn = 1O = 2H = 4Cl = 4Number of atoms on product side are as follows.
Mn = 1O = 2H = 4Cl = 4Since, 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].

which process requires more energy to be released, condensation or freezing? explain
Answers
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.
What are forces of attraction?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.

Which statement is true about the rotational period of the moon?

Answers
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."
What is rotational period?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.
What is revolution period?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.
What is moon?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.

balance FeCl3 + MgO ---> Fe2O3 + MgCl2
Answers
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.
Fe = 1Cl = 3Mg = 1O = 1Number of atoms on product side are as follows.
Fe = 2Cl = 2Mg = 1O = 3To 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.
Fe = 2Cl = 6Mg = 3O = 3Number of atoms on product side are as follows.
Fe = 2Cl = 6Mg = 3O = 3Since, 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].

Molar mass of hypomanganous acid. (H3MnO4) = 1(3) + 55 + 16(4)
= 3 + 55 + 64
= 122g/mol
According to this question, there are 22.912g of H3MnO4
mole = 22.912g ÷ 122g/mol
mole = 0.188mol
