The solution to the equation and value of variable 21(3d - 4) + 100 = 58 is d = 2/3.

Solve the equation 21(3d - 4) + 100 = 58, we can begin by simplifying and isolating the variable:

21(3d - 4) + 100 = 58

Distribute 21 to the terms inside the parentheses:

63d - 84 + 100 = 58

Combine like terms:

63d + 16 = 58

Subtract 16 from both sides:

63d = 42

Divide both sides by 63:

d = 42/63

Simplifying the fraction gives:

d = 2/3

The solution to the equation is d = 2/3.

The solution to the equation 21(3d - 4) + 100 = 58 is d = 2/3. By simplifying the equation, we find that dividing both sides by 63 results in the solution of d = 2/3, which satisfies the original equation.

Explanation: JUST TOOK THE QUIZ

Answer:

because electron is a negetively charge particle that orbits the outer part of atom and despite being small it is a strong proton.

Explanation:

The mass number of an ion with 109 electrons, 158 neutrons, and a 1 charge is 267. In atoms, the mass number is the total number of protons and neutrons in the nucleus.

However, ions are atoms that have gained or lost electrons, resulting in a change in their charge. In this case, the ion has a 1 charge, indicating that it has lost one electron. Since the number of protons remains the same for an element, which is determined by its atomic number, we can deduce that the atom originally had 110 electrons to balance the 110 protons. To find the mass number, we add the number of protons (110) and neutrons (158) since they contribute to the overall mass of the atom. Therefore, the ion's mass number is 267 (110 protons + 158 neutrons).

Answer:Atomic radius gets bigger

Explanation:

Atomic radius bigger because not only do the atoms have more and more protons and neutrons, and thus more mass in general, there is also stronger shielding affect. Shielding affect is when electrons closer to the nucleus block the positive charge from reaching electrons farther from the nucleus, and thus those far electrons are not drawn towards the nucleus as strongly, and spread out more, increasing atomic radius.

A maximum of two electrons will be placed in 1s first. With a maximum of two electrons, 2s will then be filled. With a maximum of 6 electrons, 2p will then be filled.

Answer:

In liquids, particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion.

The correct order of major climate zones for Earth when moving the North Pole to the South Pole is "Polar, Temperate, Tropical".

Starting from the North Pole and moving towards the South Pole, the first climate zone encountered is the Polar zone. This region experiences extremely cold temperatures and is characterized by ice caps, glaciers, and tundra.

Moving further towards the equator, we encounter the Temperate zone. This zone experiences moderate temperatures and is characterized by distinct seasons. It includes areas with both warm summers and cold winters.

Finally, as we approach the equator, we reach the Tropical zone. This zone is characterized by high temperatures throughout the year and abundant rainfall. It is known for its tropical rainforests, hot and humid climate, and diverse flora and fauna.

The given chemical equation is unbalanced.

An unbalanced equation is a chemical equation that does not have the same number of atoms of each element on both sides of the equation. In other words, the number of atoms of each element present in the reactants (the substances being reacted) is not the same as the number of atoms of each element in the products (the substances produced by the reaction).

The solution must be diluted with 17.9 L of water to make 1.000 L of 0.100 m Ba(OH)₂.   To find out how many ml of the solution must be diluted with water to make 1.000 L of 0.100 m Ba(OH)₂, we can use the formula:

volume of solution (v) = concentration of solute (c) * volume of solvent (v_solvent)

where c is the concentration of the solute in the original solution and v_solvent is the volume of solvent used to make the solution.

We know that the original solution has a volume of 1.800 L, a concentration of 0.100 mol/L, and a molar mass of 106.9 g/mol.

To find the mass of the solute in the original solution, we can use the molar mass and the concentration:

mass of solute = molar mass * concentration

mass of solute = 106.9 g/mol * 0.100 mol/L

mass of solute = 10.69 g

To find the volume of the solvent used to make the solution, we can use the formula:

volume of solvent = volume of solution / concentration of solute

volume of solvent = 1.800 L / 0.100 mol/L

volume of solvent = 18 L

Therefore, the solution must be diluted with 17.9 L of water to make 1.000 L of 0.100 m Ba(OH)₂

Explanation:

heavier means it goes faster

The aldehyde that is the strongest electrophile and should produce the corresponding chalcone the fastest is piperonaldehyde.

The electrophilicity of an aldehyde is determined by the electron-withdrawing or electron-donating groups present on the aromatic ring. Piperonaldehyde has a methoxy group (-OCH₃) in the para position, which is an electron-donating group. This group increases the electron density on the ring and makes the carbonyl carbon more electrophilic.

In contrast, 3-nitrobenzaldehyde has a nitro group (-NO₂) in the meta position, which is an electron-withdrawing group. This group decreases the electron density on the ring and makes the carbonyl carbon less electrophilic. p-Anisaldehyde has a methoxy group in the ortho position, which is a weak electron-donating group that has little effect on electrophilicity.

Explanation:

Neutral sulfur has an atomic number of 16.

Neutral sulfur has 16 electrons and 16 protons.

However, S²⁻ implies neutral sulfur has gain two more electrons.

So, S²⁻ is negatively charged (anion) and has 18 electrons.

Electronic Configuration

Neutal sulfur (S) → 1s² 2s² 2p⁶ 3s² 3p⁴ → [Ne] 3s² 3p⁴.

Charged sulfur (S²⁻) → 1s² 2s² 2p⁶ 3s² 3p⁶ → [Ne] 3s² 3p⁶.

Therefore, the electron configuration of S²⁻ is [Ne] 3s² 3p⁶.
