What is this equation balanced?

Answer:

This accepting atom will then become an anion. The anion has more electrons than protons. This means that some of the electrons will not be canceled out, giving the atom an overall negative charge.

If an object has more protons than electrons, then the net charge on the object is positive. If there are more electrons than protons, then the net charge on the object is negative. If there are equal numbers of protons and electrons, then the object is electrically neutral.

Answer : The molecular formula of benzoyl peroxide is [tex]C_{14}H_{10}O_4[/tex]

Explanation :

Empirical formula : It is the simplest form of the chemical formula which depicts the whole number of atoms of each element present in the compound.  

Molecular formula : it is the chemical formula which depicts the actual number of atoms of each element present in the compound.  

For determining the molecular formula, we need to determine the valency which is multiplied by each element to get the molecular formula.

The equation used to calculate the valency is :

[tex]n=\frac{\text{Molecular mass}}{\text{Empirical mass}}[/tex]

As we are given that the molar mass of compound is, 0.242 kg/mol.

Molecular mass = 0.242 kg/mol = 242 g/mol      (1 kg = 1000 g)

The empirical mass of [tex]C_7H_5O_2[/tex] = 7(12) + 5(1) + 2(16) = 121 g/eq

[tex]n=\frac{\text{Molecular mass}}{\text{Empirical mass}}[/tex]

[tex]n=\frac{242}{121}[/tex]

[tex]n=2[/tex]

Molecular formula = [tex](C_7H_5O_2)_n[/tex] = [tex](C_7H_5O_2)_2[/tex] = [tex]C_{14}H_{10}O_4[/tex]

Thus, the molecular formula of benzoyl peroxide is [tex]C_{14}H_{10}O_4[/tex]

Answer:

The evidence of matter scattering light wave in many different directions is;

D. The colors on the water's surface match the colors in the sky

Explanation:

Light scattering is used to describe the sending of a given beam of light in many directions (by tiny particles) when the light passes through a medium, due to the disruption of the bath of the light ray as it bumps into the tiny particles

Water has the nature of absorbing the red light. The light that enters the water is scattered by the tiny particles in the water such that the blue light which is the spectrum of light water allows to pass through is reflected along with the reflection of the sky and the colors of the water surface match the colors of the sky.

The number of atoms in 1 mole of carbon = the number of atoms in 1 mole of boron is not true about one mole.

It is untrue to say that one mole of fluorine gas weighs more than one mole of oxygen gas. Fluorine gas has a molar mass of 38 grams per mole, whereas oxygen gas has a molar mass of 32 grams per mole, based on their relative molar masses.

A mole of a substance is equal to 6.022 × 10²³ of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is referred to as "Avogadro's number" or "Avogadro's constant."

Since boron has a different molar mass than carbon, the statement that there are the same number of atoms in each mole is untrue.

The ratio of the substance's mass to its molar mass is used to express the number of moles of an element.

Moles  = Mass/Molar mass

Given that the molar masses of carbon and boron differ, the statement that the number of atoms in a mole of carbon is equal to the number of atoms in a mole of boron is false.

Therefore, the correct answer is option c) the number of atoms in 1 mole of carbon = the number of atoms in 1 mole of boron.

The complete question is:

Which of the following is not true about one mole?

a) the mass of 1 mole of carbon atoms = the mass of

b) 1 mole of boron atoms

one mole contains 6.02 x 1023 particles

c) the number of atoms in 1 mole of carbon = the number of atoms in 1 mole of boron

Answer:

The answer is B

Explanation:

Answer:

Molecular formula = C₄H₁₂O₂

Explanation:

Given data:

Percentage of hydrogen = 13.80%

Percentage of carbon = 51.02%

Percentage of oxygen = 35.18%

Molecular formula = ?

Solution:

Number of gram atoms of H = 13.80 / 1.01 = 13.6

Number of gram atoms of O = 35.18 / 16 = 2.2

Number of gram atoms of C = 51.02 / 12 = 4.25

Atomic ratio:

            C                      :      H             :         O

           4.25/2.2           :     13.6/2.2     :       2.2/2.2

            2                      :        6          :        1

C : H : O = 2 : 6 : 1

Empirical formula is C₂H₆O.

Molecular formula:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

Empirical formula mass = C₂H₆O = 46 g/mol

n = 88 / 46

n = 2

Molecular formula = n (empirical formula)

Molecular formula = 2 (C₂H₆O)

Molecular formula = C₄H₁₂O₂

Answer:

A. write balanced chemical equation (including states), for this process.

Explanation:

Almost all hydrocarbon 'burn' reactions involve oxygen; it's by far the most reactive substance in air.  

Hydrocarbon combustions always involve  

[some hydrocarbon] + oxygen --> carbon dioxide + steam.  

C6H6(l) + O2 (g)--> CO2 (g)+ H2O (g)

Balance carbon, six on each side:  

C6H6(l) + O2 (g)--> 6CO2 (g)+ H2O (g)

Balance hydrogen, six on each side:  

C6H6(l) + O2 (g)--> 6CO2(g) + 3H2O (g)

Now, we have fifteen oxygens on the right and O2 on the left.  

Two ways to deal with that. We can use a fraction:  

C6H6 (l)+ (15/2)O2 (g)--> 6CO2 (g)+ 3H2O (g)

Or, if you prefer to have whole number coefficients, double everything  

to get rid of the fraction:  

2C6H6 (l)+ 15O2 (g)--> 12CO2 (g)+ 6H2O (g)

With the SATP states thrown in...  

C6H6(l) + (15/2)O2(g) --> 6CO2(g) + 3H2O(g)

• Water is present in the majority of the Earth, however, of this only 3% of the water is freshwater, the rest is saline and undrinkable.  

• Of this 3%, the 75 percent of the freshwater is present in the form of ice and glaciers in the polar region.  

• The remaining 24 percent is the groundwater and the rest 1 percent includes the waters of rivers, lakes, and ponds.

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants.

The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical equation will be :

To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. Therefore, the correct option is option A.

Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.

In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron. Just like the N and S poles on bar magnets, electrons and protons attract each other.

Therefore,  the correct option is option A.
