We need 25.5 g of KCl and 274.5 g of water to make 300. g of 8.50% KCl solution.
To find the masses of potassium chloride (KCl) and water needed, we need to use the concentration of the solution and the total mass of the solution.
We need to find the mass of KCl in the solution. We know that the solution is 8.50% KCl by mass, so:
mass of KCl = 8.50% x 300. g = 25.5 g
We can find the mass of water in the solution by subtracting the mass of KCl from the total mass of the solution:
mass of water = 300. g - 25.5 g = 274.5 g
To create 300 g of 8.50% KCl solution, we need 25.5 g of KCl and 274.5 g of water.

determine the number of electrons lost or gained when each atom forms an ion.
Be: Loses 2 electrons, Se: Gains 2 electrons, I: Gains 1 electron, As: Gains 3 electrons.
The electron, a subatomic particle, has a negative fundamental electric charge. Electrons, the first generation of the lepton particle family, are often regarded as elementary particles due to their lack of known components or substructure. The mass of a proton is roughly equivalent to that of an electron. One of the quantum mechanical characteristics of the electron is its intrinsic angular momentum (spin), which is measured in terms of the reduced Planck constant. Because electrons are fermions, the Pauli exclusion principle asserts that no two of them may be in the same quantum state. Electrons have features in common with all elementary particles, including the ability to collide with other particles and experience optical diffractive effects. The wave properties of electrons are easier to observe experimentally than those of neutrons and protons because they have a smaller mass and a longer de Broglie wavelength for a given energy than these other particles do. Along with many other scientific phenomena including electricity, magnetism, chemistry, and thermal conductivity, electrons are involved in gravitational, electromagnetic, and weak interactions.

Calcium nitrate- make an evidence based argument for why acid rain would cause the calcium carbonate in the marble to slowly break down and wash away over time when calcium nitrate is produced
Following are the effects of acid rain.
What is Acid Rain?
Acid rain is caused by the accumulation of nitric and sulfuric acids in the atmosphere. These compounds are strong acids and are very soluble in water, dissolving in droplets in clouds.
Limestone effect:
Calcium carbonate, [Ca][CO3], is a very common mineral. A limestone is a well-known form of calcium carbonate. The acid contained in acid rain reacts with carbonate ions and promotes the dissolution of calcium carbonate.
This will create a bicarbonate solution. The presence of limestone and other calcium carbonates in lakes and streams helps maintain a constant pH as the mineral reacts with excess acidity. However, acid rain can eventually exceed the buffering capacity of surface waters.
How does acid rain affect buildings made of marble and limestone?
It is mainly affected in 2 ways: dissolution and alteration. Calcite dissolves when sulfuric, sulfuric and nitric acids in polluted air react with calcite in marble and limestone. Exposed areas of buildings and statues show rough surfaces, worn materials, and loss of sculptural detail. Stoneface material can be lost anywhere or only in more reactive areas.
Hence, this is how acid rain affects.

If 1.82 mol of ZnS is heated in the presence of 3.94 mol of O2, which is the limiting reactant?
Answer:
In Explanation
Explanation:
In a chemical reaction, the limiting reactant is the reactant that is completely consumed before any of the other reactants are used up. The amount of product that can be formed is determined by the limiting reactant, and the amount of the excess reactant left over after the reaction can be calculated.
To determine which reactant is the limiting reactant, we need to compare the stoichiometry of the reaction, which is the ratio of the reactants and products in a balanced equation.
The balanced equation for the reaction between ZnS and O2 is :
ZnS + O2 → ZnO + SO2
From the balanced equation, we can see that 1 mole of ZnS reacts with 1 mole of O2 to form 1 mole of ZnO and 1 mole of SO2.
Now we can compare the amount of ZnS and O2 that we have with the stoichiometry of the reaction.
1.82 moles of ZnS is enough to react with 1.82 moles of O2
But we have 3.94 moles of O2, which is more than enough to react with the 1.82 moles of ZnS
Therefore ZnS is the limiting reactant and O2 is the excess reactant.

The substance in each of the following pairs would you expect to have larger dispersion forces are a) octane having larger dispersion forces b) HI having larger dispersion forces c) H₂Se having larger dispersion forces.
What exactly does dispersion force entail?The temporary attractive force that results when two nearby atoms temporarily form dipoles because of the positions of their electrons is referred to as the London dispersion force. Another name for this force is an induced dipole-induced dipole attraction.
First, because there are more electrons in larger molecules, and because some of those electrons are less tightly bound and farther from the nucleus, making them more polarizable, larger molecules have stronger dispersion forces.
Second, because a more dispersed molecule has a larger surface area and more surface contact with other molecules, the dispersion forces are larger.
a) Ethane, C₂H₆ or octane, C₈H₁₈
Based on the structures of ethane and octane, octane is longer and less impact than ethane, since octane is more spread out hence octane having greater surface area has larger dispersion forces compared to ethane
