Hydrogen carbonate is indeed a white, mainly crystalline substance. Therefore, sodium bicarbonate is an ionic salt.

Baking soda is made from hydrogen carbonate (sodium hydrogen carbonate). Furthermore, it is a chemical molecule with the formula NaHCO3. It is a salt that consists of such a sodium cation (Na+) and a bicarbonate anion (HCO3).

Hydrogen carbonate is indeed a white, mainly crystalline substance. However, it frequently seems to be a fine powder. It tastes somewhat alkaline and salty, comparable to washing soda (sodium carbonate).

Therefore, hydrogen carbonate is an ionic salt.

Hi again. The lactose in the milk is converted to lactic acid by microbes. It has turned into a new substance that is irreversable.

The correct IUPAC name for the tertbutyl substituent is a. (1,1-dimethylethyl). This is because the tertbutyl group is a branched alkyl group with four carbon atoms.

The prefix "tert-" indicates that the carbon atom attached to the rest of the molecule is attached to three other alkyl groups. The prefix "but-" indicates that the group has four carbon atoms, and the suffix "-yl" indicates that it is an alkyl group. The prefix "1,1-dimethyl-" indicates that there are two methyl groups attached to the first carbon atom of the butyl group. Therefore, the correct IUPAC name for the tertbutyl substituent is (1,1-dimethylethyl).
It is important to know the correct IUPAC name of a molecule or substituent because it provides a standardized way of naming compounds, which allows chemists to communicate effectively and avoid confusion. The IUPAC naming system is based on a set of rules that can be applied to any organic compound, allowing for easy identification and classification of different compounds.

According to the law of conservation of mass, the total mass of the reactants in a chemical reaction is equal to the total mass of the products.

This means that the mass of the reactants before the reaction is the same as the mass of the products after the reaction. In other words, mass is neither created nor destroyed during a chemical reaction, it is only transformed from the reactants into the products.

Therefore, the masses of the reactants and the products in a chemical reaction are directly related and must balance each other. This relationship is fundamental in chemistry and is used to calculate the amount of reactants and products in a chemical reaction, as well as to predict the outcome of the reaction.

Answer:

Ka = 9.2x10⁻⁷

Explanation:

The equilibrium of carbonic acid in water is:

H₂CO₃ ⇄ HCO₃⁻ + H⁺

Where Ka is defined as:

Ka = [HCO₃⁻] [H⁺] / [H₂CO₃]

The equilibrium concentration of the species is:

[H₂CO₃] = 1.9x10⁻² - X

[HCO₃⁻] = X

[H⁺] = X

As pH is -log[H⁺]

3.88 = -log[H⁺]

1.318x10⁻⁴ = [H⁺] = X

Replacing:

[H₂CO₃] = 1.9x10⁻² - 1.318x10⁻⁴ = 1.8868x10⁻²

[HCO₃⁻] = 1.318x10⁻⁴

[H⁺] = 1.318x10⁻⁴

Replacing in ka equation:

Ka = [1.318x10⁻⁴] [1.318x10⁻⁴] / [1.8868x10⁻²]

Answer:

No

Explanation:

There are no interactive forces (i.e., attraction or repulsion) between the particles of a gas.

The average kinetic energy of gas particles is proportional to the absolute temperature of the gas, and all gases at the same temperature have the same average kinetic energy.

The fact that radon is a gas and can enter basements through any cracks makes it a potential health risk. Radon decays into radioactive polonium (Z = 84) and has a half-life of 3.8 days.

Ra-226 has a half-life of 1600 years, a significant difference from the other radioactive isotopes of radium that decay over a short period of time. It possesses 138 neutrons in its nucleus and 88 protons, which is equal to the number of electrons in its shells, giving it a mass number of 226.

A reaction's half-life is the amount of time needed for the reactant concentration to drop to half its initial value.

Answer: Most Hydrocarbon chains are found in petroleum, coal, and natural gas. First of all, a hydrocarbon chain is a molecule that consist of entirely hydrogen and carbon.

Explanation: There are many types of hydrocarbon chains, which can be found in alkanes, alkynes, arenes, alkenes, and cycloalkanes. Natural rubber for instance is a hydrocarbon that primarily consists of alternating single and double bonded carbons.

The water retained by some salts when isolated by evaporation is called water of hydration. Salts that contain water of hydration are called hydrates.

Water of hydration is also called water of crystallization. It is the water that remains inside the framework of the salt or crystal after evaporation and can only be removed by heating, but by doing this, one risks losing the structure of the crystal.

An example of a hydrate is copper tetraoxosulphate (VI). When hydrated, it becomes copper tetraoxosulphate (VI) pentahydrate. When it is without its water of hydration, it has a white colour but when it is hydrated, it is blue in colour.

The original concentration of the gold chloride solution was 0.52 M.

To determine the original concentration of the gold chloride solution, we can use the concept of dilution. When two solutions of different concentrations are mixed together, the resulting concentration can be calculated using the formula:

C1V1 = C2V2

where C1 and V1 represent the initial concentration and volume, and C2 and V2 represent the final concentration and volume.

Given that the final volume is 1 liter and the final concentration is 0.26 M, and the volumes of the original and added solutions are both 0.5 liters, we can substitute these values into the formula:

C1 * 0.5 L = 0.26 M * 1 L

Simplifying the equation:

C1 = (0.26 M * 1 L) / 0.5 L

C1 = 0.52 M

The calculation is based on the assumption that the dilution process is an ideal dilution, where there is no change in the total amount of gold chloride present in the solution during the mixing process. Additionally, it assumes that there are no chemical reactions or interactions between the two solutions.

Benzoic acid, HX, is a weak acid that reacts with OH- as follows:

HX + OH- → X- + H2O

Where X- is produced, the conjugate base of benzoic acid.

As benzoic acid is a weak acid, benzoate ion is a strong base. A strong base has pH > 7. Right option is:

D. > 7

Answer:

100c

Explanation:

Answer:

Explanation:

To solve the question above we must first find the pH of the solution using the formula

pH + pOH = 14

pOH = 3.1

So we have

pH + 3.1 = 14

pH = 14 - 3.1

pH = 10.9

Since it's pH is 10.9 the solution is a basic solution since it's pH lies in the basic region.
