Minerals are inorganic substance, structurally simple substances free of carbon atoms.

All substances that are not organic and do not have a carbon-to-carbon (C-C) or carbon-to-hydrogen (C-H) bond are considered inorganic substances. Aqua, table salt (NaCl), sodium bicarbonate, calcium carbonate, and muriatic acid are some examples of typical everyday inorganic compounds (industrial-grade hydrochloric acid).

Compounds classified as organic are those derived either indirectly or directly from animals and plants. Inorganic compounds are those compound which are made from minerals. Many times, simple carbon compounds are regarded as inorganic. Examples include carbon monoxide, carbon dioxide, carbides, and the many forms of carbon (such as graphite, diamond, buckminsterfullerene, etc.).

Molal boiling-point elevation is a term used in thermodynamics and refers to the change in boiling point of a solvent due to the addition of a non-volatile solute. The molal boiling-point elevation is proportional to the molality (number of moles of solute per kilogram of solvent) of the solution and is an important colligative property, which means it depends only on the concentration of solute particles and not on their identity.

The molal boiling-point elevation can be calculated using the equation ΔTb = Kb × m, where ΔTb is the change in boiling point, Kb is the molal boiling-point elevation constant, and m is the molality of the solution. The value of Kb is different for each solvent and is used to quantify the effect of the solute on the boiling point of the solvent.

Molal boiling-point elevation has several important applications, including the purification of liquids by fractional distillation, the determination of the concentration of dissolved substances, and the production of high-purity solvents. It is also used in the food and pharmaceutical industries, where the boiling point of solutions is often used as a quality control criterion.

Calculations:

mass of Cu = 0.3 g - (0.2 g x (63.55 g/mol / 65.39 g/mol))

Answer:

mass of Cu = 0.27 g

Answer:

To calculate the mass of copper produced in this reaction, you need to know the mass of CuSO4 and Zn used and the balanced chemical equation for the reaction. Without this information, I cannot perform the calculation for you.

A pair of electrons would have more electric potential energy when they are close together than when they are far apart.

The system's potential energy grows when two like charges—two protons or two electrons—are brought adjacent to one another. A proton and an electron, which are two different charges, are moved towards one another, the electric potential energy of the system diminishes.

Due to the same negative charge, a repulsive force is generated between two electrons as they approach one another. So, a battle is waged against this repellent energy in an attempt to bring them closer. Electrostatic potential energy is used to store this work.

13.74 gm of a 0.500 m solution of sodium acetate, in water would you use to obtain 0.170 mol of sodium acetate.

To calculate the mass of sodium acetate in a 0.500 m solution, use the following equation:-

= Mass (g)

= Molarity (m) x Volume (L) x Molecular Weight (g/mol).

For sodium acetate, the molecular weight is 82.03 g/mol. Therefore, the mass of sodium acetate in a 0.500 m solution is:

= Mass (g)

= 0.500 m x 0.500 L x 82.03 g/mol

= 20.51 g

To obtain 0.170 mol of sodium acetate, use the following equation:-

Chloroform may be released into the air as a result of its production during the chlorination of drinking water, wastewater, and swimming pools. Chloroform, a substance used in industry, is a lacrimator.

From CH4 + 3 Cl2 comes CHCl3 + 3 HCl.

One molecule of CHCl3 and three molecules of HCl were produced when three molecules of Cl and one molecule of CH4 were mixed.

This predicts a 1:1 ratio between CH4 and CHCl3.

Due to the 1:1 ratio, the amount of CHCl3 produced is 66.5/119.5 (molar mass of CHCl3), or 0.556 moles, and the amount of CH4 produced is 0.556 moles mass, or 0.556 x 16 (molar mass of CH4), which equals 8.896 grams.

Answer:

Explanation:

Electroplating is the process of depositing a thin layer of one metal onto the surface of another metal or conductive material by means of an electrochemical reaction. In the case of silver electroplating, the following half reactions occur at the anode and cathode:

Anode (Oxidation): Ag(s) -> Ag+ (aq) + e-

Cathode (Reduction): Ag+ (aq) + e- -> Ag(s)

At the anode, silver atoms dissolve into the solution, releasing electrons and forming silver ions (Ag+). At the cathode, the silver ions gain electrons and precipitate out as solid silver atoms, which deposit onto the surface of the object being plated. This process continues until the desired thickness of silver has been deposited.

The anode and cathode are separated by a conductive material, typically an electrolyte solution, and a direct electrical current is applied to the system. The electrical current drives the reaction at the anode and cathode, with the electrons flowing from the anode to the cathode through the electrical circuit, allowing the silver ions to travel from the anode to the cathode, where they deposit as solid silver.

The mole fraction of 13.2g of CH₄ in the given problem when dissolved in 52.4g of C₂H₆O is 0.42.

Mole fraction of CH₄ in C₂H₆O  can be calculated in three steps:

1. The masses of CH₄ and C₂H₆Oneed to be converted into moles:

The mass of CH₄= 16.04g/mol

Therefore, the moles of CH₄ present in 13.2g = 13.2/16.04 moles = 0.82 moles.

The mass of C₂H₆O = 46.07 g/mol

Therefore, the moles of C₂H₆O present in 52.4g = 52.4/46.07 = 1.14 moles.

2. The total number of moles of solutes need to be calculated next,

Moles of CH₄+ Moles of C₂H₆O = 0.82 + 1.14 moles = 1.96 moles.

3. The last step is to divide the moles of CH₄by the total moles of solute = 0.82/1.96 = 0.42 moles.

When a solute is added to a pure solvent the freezing point decreases as the boiling point increases.

The temperature at which a substance's liquid and solid forms have the same vapour pressure is known as its freezing point. Vapour pressure decreases as soon as a solute is added to the solvent. As a result, the temperature where the vapour pressure of the solid and liquid phases is equal is likewise decreased, and the freezing point is lowered as a result.

The temperature at which air pressure and vapour pressure are equal is known as the boiling point. Because there are fewer water molecules on the surface of the salt solution, fewer water molecules evaporate, resulting in lower vapour pressure. Therefore, a greater temperature was required to reach atmospheric pressure, consequently, the boiling point rises.
