explain the concept of thekinetic molecular theory

Answers

Answer 1

Answer:

Kinetic Molecular Theory states that gas particles are in constant motion and exhibit perfectly elastic collisions. Kinetic Molecular Theory can be used to explain both Charles' and Boyle's Laws. The average kinetic energy of a collection of gas particles is directly proportional to absolute temperature only.

How do covalent compounds differ from ionic compounds?

Answers

Answer:

1. Ionic bonds result from transfer of electrons, but covalent bonds are formed by sharing.

2. Ions are arranged in a three-dimensional array (like crystals). Covalently bonded substances exist as discrete molecular units.

3. Ionic compounds often dissociate into ions in solution, but covalently bonded molecules retain their molecular identity in solution.

BALANCING CHEMICAL EQUATION:

Balancing a chemical equation means ensuring that the number of atoms of each element on both sides of the equation are the same in accordance to the law of conservation of mass.

To balance a chemical equation, we make use of coefficients, which are numbers placed in front of the element or compound in the reaction.

According to this question, the following equation: 2HgO → 2Hg + O2, is correctly balanced because the number of atoms of Hg (2) and O (2) are the same on both sides.

Explanation:

Labor unions arose in the nineteenth century as increasing numbers of Americans took jobs in factories, mines, and mills in the growing industrial economy.

The Knights of Labor, founded in 1869, was the first major labor organization in the United States. The Knights organized unskilled and skilled workers, campaigned for an eight hour workday, and aspired to form a cooperative society in which laborers owned the industries in which they worked.

The Knights’ membership collapsed following the 1886 Haymarket Square riot in Chicago. By 1886 the American Federation of Labor (AFL), an alliance of skilled workers’ trade unions, was growing.

A diprotic acid (H2X) titrated with a solution of NaOH for 25 ml of the acid 87.42 ml of a 1.95 M solution of NaOH was required to reach the equivalent point, the concentration of the diprotic acid equals

Answers

The concentration of the diprotic acid equals 3.4 M

We'll begin by writing the balanced equation for the reaction.

H₂X + 2NaOH —> Na₂X + 2H₂O

From the balanced equation above,

The mole ratio of the acid, H₂X (nA) = 1The mole ratio of the base, NaOH (nB) = 2

From the question given above, the following data were obtained:

Volume of acid, H₂X  (Va) = 25 mLVolume of base, NaOH (Vb) = 87.42 mLMolarity of base, Ca(OH)₂ (Mb) = 1.95 MMolarity of acid, H₂X (Ma) =?

MaVa / MbVb = nA/nB

(Ma × 25) / (1.95 × 87.42) = 1/2

(Ma × 25) / 170.469 = 1/2

Cross multiply

Ma × 25 × 2 = 170.469

Ma × 50 = 170.469

Divide both side by 50

Ma = 170.469 / 50

Ma = 3.4 M

Therefore, the concentration of the acid, H₂X is 3.4 M

Lift the kitten's tail. The opening just under the tail is the anus. Below the anus is the genital opening which is round in males and is a vertical slit in females. In kittens of similar size, the distance between the anus and the genital opening is greater in the male than the female.

TW: use of inapropate words*

Answer:

not enough information to tell

Explanation:

One way you can tell this difference is the distance between the cat's genitals (organs seen on the outside of the body) and the anus.  A male will have a much greater distance between the genitals and anus than females, 1/2 inch apart on a male kitten and over 1 inch apart on a male adult cat.  However, if the two are almost adjacent on a kitten or less than 1/2 inch apart on an adult, it’s a female.

Which of the following substances would have the strongest

A) HF (Hydrogen Fluoride)
B) HCI (Hydrogen Chloride)
C) HBr (Hydrogen Bromide)
D) HI (Hidrogen lodide)

Answers

Answer:

A) HF (Hydrofluoric acid)

Explanation:

dw I gotchu. So first off there are three types of intermolecular forces of attraction: 1) London-Dispersion, 2) Dipole-Dipole, 3) Hydrogen-Bonding Attraction Forces. That is also ranked in increasing strength, with Hydrogen-Bonding Attraction Forces being the strongest. Every molecule has London-Dispersion forces present and all the diatomic molecules listed have dipole moments of a certain debye (or Coloumb-meter) value. Both are irrelevant here so dw about that. Lets look at the strongest attraction: the hydrogen-bonding one. Now, don't get confused bc all of these acids are bonded to H bc hydrogen-bonding attraction forces only occur when H is bonded to N, O, or F. So Process of Elimination, hydrofluoric acid (HF) has the strongest intermolecular forces of attraction.

Note: If you don't know what inter/intra molecular forces of attraction are, ill give u a quick summary. Intermolecular refers to electrostatic attractions between molecules while intramolecular refers to the actual bonds, single, double, or triple, binding the atoms together. Well there you have it, have a great day. :)

A force of 5N accelerates an object. The object mass is 50 g. What is the acceleration of an object?

Answers

Answer:

100 m/ s²

Explanation:

Newton's Second Law of Motion:

[tex] \boxed{ \mathsf{force = mass \times acceleration}}[/tex]

___________________

In the question:

Force applied = 5 N mass of the object experiencing force = 50 g

Note that the quantities here must be in their SI units.

SI unit of Force is Newton(N).

SI unit of mass is kilogram(kg)

Force is already in it's SI unit, while mass isn't.

Converting mass from grams to kilograms:

1000 g = 1 kg

=> 1 g = 1/ 1000 kg

=> 50 g = 50/ 1000 kg

= 1/ 20 kg

___________________

Calculating acceleration:

[tex] \mathsf{5 = \frac{1}{20} \times acceleration }[/tex]

multiplying both sides by 20:

[tex] \implies \mathsf{5 \times 20= (\frac{1}{20} \times 20)\times acceleration }[/tex]

20 on the RHS gets canceled, for it's present on the numerator as well as the denominator.

[tex] \implies \mathsf{100= acceleration }[/tex]

So, here, we got acceleration = 100 m/s².

Since, the other quantities used in the formula are in their SI units, acceleration must be in it's SI unit as well.

The SI unit of acceleration is m/s²

___________________

Answer:

[tex] \boxed{ \mathsf{100 \:m/s^2= acceleration }}[/tex]

4. Initially, 1 mol of oxygen (assumed to be an ideal gas) has temperature 310 K and volume 12 L. We will allow it to expand to volume 19 L. (a) What would be the final temperature if the gas expands adiabatically

Answers

Answer:

490.83 oK

Explanation:

First of all, we better agree on the meaning of the word adiabatically. It means without the loss or gain of heat. So nothing is given up to or taken from the environment.

This also assumes that no change has occurred in the pressure.

T1 = 310 oK

T2 = ?

V1 = 12 L

V2 = 19 L

T1/V1 = T2/V2

310 / 12 = x/19            Multiply both sides by 19

310*19 / 12 = T2         Multiply 310 * 19 on the left.

5890 / 12   = T2         Divide by 12

490.83 = T2

Answer:

We know the initial volume of the potassium nitrate solution is 1.0 mL and the initial concentration is 2.0 M, we also know that an unknown volume of water was added to the solution, which diluted our concentration down to a final value of 0.008 M. We are trying to find the final volume.

Here we can use this formula since the initial and final solutions are proportional. Before that let's define our variables.

[tex]M_1 = 2.0 M\\V_1 = \frac{1.0 mL}{1000} = 0.001 L\\M_2 = 0.008 M\\V_2 = \ ?[/tex]

[tex]M_{1}V_{1} =M_2 V_2\\[/tex]

[tex](2.0)(0.001) = (0.008)V_2\\\\\frac{(2.0)(0.001)}{0.008} = V_2\\\\V_2 = 0.25 L \ or \ (0.25 \ * \ 1000) = 250 \ mL[/tex]

Therefore you would have 0.25 L or 250 mL of your final solution.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.
