Explanation:

The force of the car can be calculated using Newton's second law of motion, which states that the force acting on an object is equal to its mass multiplied by acceleration.

So, the force of the car can be calculated as follows:

Force = Mass * Acceleration

Force = 300 kg * 10 m/s^2

Force = 3000 N

Therefore, the force of the car is 3000 N.

The correct name for the molecule C₁₁H₂₄ is 3-ethyl-5-propylhexane (option B).

The molecule C₁₁H₂₄ consists of an eight-carbon chain (octane) with an ethyl group attached at the third carbon and a propyl group attached at the fifth carbon. This gives the molecule a total of eleven carbon atoms, which is why it is called an undecane. The formula C₁₁H₂₄ indicates that there are 24 hydrogen atoms in the molecule (2 for each carbon atom).

Since the molecule has two different types of substituent groups, it is named using the IUPAC system. The names of substituent groups are arranged alphabetically and preceded by a number that indicates the position of the group on the chain. In this case, the ethyl group is at the third position and the propyl group is at the fifth position. Therefore, the name of the molecule is 3-ethyl-5-propylhexane.

The atomic number (Z) of Iminium (Im) is 125, and since alpha decay results in the loss of 2 protons, Z will decrease by 2, giving a value of 123 for the newly formed element.

After a decay event by alpha decay, the Iminium (Im) atom with atomic number 125 (Z) and atomic mass number 282 (A) will change. Alpha decay involves the loss of 2 protons and 2 neutrons from the nucleus. Therefore, the new values for A and Z will be:

- New atomic number (Z) = 125 - 2 = 123
- New atomic mass number (A) = 282 - 4 = 278

So, the atom that was formerly 282Im will now have an atomic number (Z) of 123 and an atomic mass number (A) of 278.

The rate law that is consistent with the proposed mechanism is [-d[H₂]/dt = k[H₂][ICl].

The sum of the two processes produces the overall reaction, which is:

H₂(g) + 2ICl(g) → 2HCl(g) + I₂(g)

We must take into account the rate-determining step, which is the step with the slowest rate, in order to derive the rate law for the total reaction. It is step 1 in this instance.

H₂(g) + ICl(g) → HI(g) + HCl(g) is the rate-determining step (g)

This step's rate rule is-d[H₂]/dt = k[H₂][ICl]

[ICl]

We can assume that the concentration of HI is always in equilibrium with the concentrations of H₂ and ICl because step 2 is quick.

Therefore, -d[H₂]/dt = k[H₂][ICl] is the rate law for the entire reaction.

Therefore,  [-d[H₂]/dt = k[H₂][ICl] is the rate law that is consistent with the hypothesized mechanism.

The percent yield of the reaction is 30%.  

The balanced chemical equation for the reaction between a cooper wire and a silver nitrate solution is:

\(2AgNO_3(aq) + 2Cu(s) - > 2Ag(s) + 2NO_3- (aq) + Cu(NO_3)_2(aq)\)

In this reaction, the copper wire acts as the reducing agent, and the silver nitrate solution acts as the oxidizing agent. The silver from the copper wire is reduced to silver metal, and the silver nitrate is oxidized to silver ions.

The theoretical yield of silver can be calculated by using the stoichiometric coefficient of silver in the balanced equation:

Theoretical yield = (2 * moles Ag) / (moles Ag - moles Cu)

The theoretical yield of silver is 2 moles.

If 60 g of silver is actually recovered from the reaction, the percent yield of the reaction can be calculated by dividing the actual yield by the theoretical yield and multiplying by 100:

Percent yield = (60 / 2) * 100%

Percent yield = 30%

d. It's important to note that electrons in higher energy levels have more energy than those in lower energy levels. The atomic number of iron (Fe) is 26, which means it has 26 electrons.

To determine how many electrons are in the third principal energy level (n = 3) of one atom of Fe, we need to use the formula 2n^2, where n is the principal quantum number.

For n = 3, we get 2(3)^2 = 18. Therefore, there are 18 electrons in the third principal energy level of one atom of Fe, so the answer is d.
It's important to note that electrons in higher energy levels have more energy than those in lower energy levels.

Answer:

solid ,hard, not see through

Explanation:

Answer:

There are many properties out there, so three include bright yellow color, luster shine, and the maleability that determines the durability.

The similarities between chemical and nuclear energy sources are that they both involve energy transformations through reactions. Both types of reactions involve the rearrangement of atoms to form new molecules or elements.

However, the main difference between them is the amount of energy released. Nuclear reactions release a much larger amount of energy than chemical reactions. In fact, nuclear reactions can release up to a billion times more energy than chemical reactions. This is due to the much stronger forces involved in nuclear reactions, as compared to the relatively weaker chemical bonds. Additionally, nuclear reactions involve changes to the nucleus of an atom, whereas chemical reactions involve changes to the outer electrons of atoms.

Answer:

The pressure exerted by 66.0 g of CO₂ gas at -14.5°C that occupies a volume of 50.0 L is 0.636 atm.

How do we calculate pressure?

Pressure of any gas will be calculated by using the ideal gas equation as:

PV = nRT, where

P = pressure of gas = ?

V = volume of gas = 50L

R = universal gas constant = 0.082 L.atm/K.mol

T = temperature of gas = -14.5°C = 258.65 K

n is moles of gas and it will be calculated as:

n = W/M, where

W = given mass of CO₂ = 66g

M = molar mass of CO₂ = 44 g/mol

n = 66/44 = 1.5 moles

On putting values we get

P = (1.5)(0.082)(258.65) / (50)

P = 0.636 atm

Hence required pressure is 0.636 atm.

The value of Kw at the given temperature is 3.78 x 10^(-14).

To calculate the value of Kw at the given temperature, we can use the equation: Kw = [H+][OH-]

Since the pH of the solution is 11.94, we can calculate the concentration of H+ ions using the equation:

[H+] = 10^(-pH)

[H+] = 10^(-11.94)

[H+] = 1.26 x 10^(-12) M

Since the solution is 0.030 M LiOH, the concentration of OH- ions is also 0.030 M.

Now we can calculate the value of Kw:

Kw = [H+][OH-]

Kw = (1.26 x 10^(-12)) * (0.030)

Kw = 3.78 x 10^(-14)

Therefore, the value of Kw at the given temperature is 3.78 x 10^(-14).
