Answer:

A polar covalent bond will have the electrons shifted more towards one side or the other; a nonpolar bond will have evenly distributed electrons.

Explanation:

  The basis for a polar bond is that the electrons are shared unevenly. Some elements are more electronegative than others; that is, they pull harder on the electrons and tend to have more electrons around them. Following the periodic trends, Fluorine is the most electronegative element, so it will likely have the most dense area of electrons in a molecule. All this means that in a polar molecule, the electrons will be spread out unevenly along the lengths of the bonds as some elements will pull on them more than others will.

  Nonpolar molecules do not have to worry about differences in electronegativity, and so the electron density will be pretty evenly distributed along the entire molecule.

•Why do you feel the force of Earth's gravity?

Answer:

•Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That's what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here.

1. The empirical formula of the compound is HNO₃. The name of the compound is trioxonitrate (v)

2. The empirical formula of the compound is PbN₂O₄ or  Pb(NO₂)₂

3. The molecular formula of the compound is N₂O₅

Divide by their molar mass

H = 1.6 / 1 = 1.6

N = 22.2 / 14 = 1.586

O = 76.2 / 16 = 4.7625

Divide by the smallest

H = 1.6 / 1.586 = 1

N = 1.586 / 1.586 = 1

O = 4.7625 / 1.586 = 3

Thus, the empirical formula of the compound is HNO₃ and the name of the compound is trioxonitrate (v)

Divide by their molar mass

Pb =13 / 207 = 0.0628

N = 1.77 / 14 = 0.1264

O = 4.03 / 16 = 0.2519

Divide by the smallest

Pb = 0.0628 / 0.0628 = 1

N = 0.1264 / 0.0628 = 2

O = 0.2519 / 0.0628 = 4

Thus, the empirical formula of the compound is PbN₂O₄ or Pb(NO₂)₂

We'll begin by determining the empirical formula of the compound. This can be obtained as follow:

Divide by their molar mass

N = 4.04 / 14 = 0.2886

O = 11.46 / 16 = 0.71625

Divide by the smallest

N = 0.2886 / 0.2886 = 1

O = 0.71625 / 0.2886 = 2.5

Multiply by 2 to express in whole number

N = 1 × 2 = 2

O = 2.5 × 2 = 5

Thus, the empirical formula of the compound is N₂O₅

Finally, we shall determine the molecular formula of the compound. This can be obtained as follow:

Molecular formula = empirical × n = molar mass

[N₂O₅]n = 108

[(2×14) + (16×5]n = 108

[28 + 80]n = 108

108n = 108

Divide both side by 108

n = 108 / 108

n = 1

Molecular formula = [N₂O₅]n

Molecular formula = [N₂O₅] × 1

Molecular formula = N₂O₅

The type of inheritance displayed by the illustration is incomplete dominance.

It is a kind of inheritance in which one of the two alleles of a gene exerts incomplete influence on the other allele.

For example, a cross of white and red flower plants yielding a plant with pink flowers. It means that the dominance of the red or pink allele is incomplete.

Answer:

30mL is required

30ml of a 2.50 M hydrochloric acid solution is required to make 100.0 mL of a 0.750 M solution.

HCl is an acid which is made up of hydrogen and chlorine gas.

By the formula of dilution

M1V1 = M2V2

where V1 = 2.50 m

M2 = 100.0

V2 = 0.750 m

M1 × 2.50 m = 100.0 × 0.750 m

M1 = 30 ml

Thus, the M1 is 30 ml option a is correct.

Explanation:

Electrolysis is a process, which allows us to break down a chemical compound into its elements, completing the balance by adjusting the number of atoms on both sides of the reaction is important because the number of electrons given up during oxidation must be the same as the number of electrons gained during the reduction.

It is a process of oxidation and reduction of one or more elements that, through the induction of electric current, breaks down the water molecule (H2O), thus producing gaseous hydrogen and oxygen.

Oxidation and reduction processes occur simultaneously and never in isolation, which is why they are called redox reactions.

Therefore, we can conclude that electrolysis is a process where electrical energy will change to chemical energy where it is important that the number of electrons given up during oxidation is the same as the number of electrons gained during reduction.
