Why can't the equilibrium constant (Kc) be negative?
The Equilibrium constant (Kc) cannot be negative as it is a ratio between the concentration of the reactant and the concentration of the product.
What is the Equilibrium constant (Kc)?For an arbitrary chemical reaction,
aA + bB ⇆ cC + dD
Kc = [Concentration of product] / [Concentration of reactant]
The equilibrium constant is defined as the ratio of product concentration to that of reactant concentration. It is measured in moles per liter. It is an important parameter for understanding chemical reactions in equilibrium.

The acid equivalent of the antacid tablet is 0.303 g HCl/ g antacid.
What is mole?
In chemistry, the term "mole" (sometimes written "mole") refers to a standard scientific unit for measuring vast amounts of extremely small objects like atoms, molecules, or other specific particles.
The mole represents 6.02214076 × 10²³ units, an astronomically huge number.
We have,
Total moles of HCl added = 0.1038 M × 50.0 mL × 1L/1000mL
= 0.00519 mol
Now, volume of NaOH used = 22.82mL - 2.30 mL
= 20.52 mL
Moles of NaOH used = 0.1017 M × 20.52 mL × 1L/1000mL
= 0.00209 mol
Moles of HCl that reacted with antacid = 0.00519 - 0.00209 mol
= 0.0031 mol
Total mass of HCl reacted = 0.0031 × 36.45g HCl / 1mol HCl

in an aqueous chloride solution cobalt(ii) exists in equilibrium with the complex ion . is pink and is blue. at low temperature the pink color predominates. at high temperature the blue color is strong. if we represent the equilibrium as: we can conclude that:
For the given condition, we can conclude that the reaction is an endothermic reaction and to maintain equilibrium the reaction shifts to right side.
Co²⁺(aq) + 4Cl⁻(aq) ⇄ CoCl₄²⁻(aq).
Endothermic reactions are reactions where the reactants absorb heat from its surrounding while the formation of product. These reactions usually reduce the surrounding temperature.
In the given condition it is said that cobalt (ii) exists in equilibrium with complex ion, is blue and pink in color. At low temperature the pink color dominates and at higher temperature, the blue color dominates.
As the given reaction is a reversible reaction, it is easier to maintain the equilibrium. The reaction forms more products in order to maintain the equilibrium. Thus, the reaction absorbs heat and shifts towards right side making the blue color predominant at higher temperature.

explain the chemistry underlying the disinfection of water by chlorination. what is the active agent in the destruction of the pathogens? what are the practical sources of the active ingredient?
The chemistry underlying the disinfection of water by chlorination involves the use of chlorine to oxidize and kill pathogens in the water.
Chlorine is the active agent in the destruction of the pathogens, and it works by breaking up the cell walls of the bacteria and other microorganisms.
The practical sources of the active ingredient include chlorine gas, hypochlorite, and chlorine dioxide.
Chlorine gas is usually produced in a laboratory and is then added to the water. Hypochlorite is a salt that can be added to the water, while chlorine dioxide is a gas that is typically applied in the form of tablets or powder.
Chlorination is a process used to disinfect water by adding chlorine or a chlorine-containing compound, such as sodium hypochlorite or calcium hypochlorite. Chlorine is a powerful oxidant, which reacts with the organic materials in the water, such as proteins, carbohydrates, and fats, to form compounds that are toxic to many bacteria and viruses. The active agent in the destruction of the pathogens is the chlorine.
The practical sources of the active ingredient are chlorine gas, sodium and calcium hypochlorite. Chlorine gas is the most common form used for disinfecting water and is typically used in larger municipal water systems. It is released into the water as a gas and quickly breaks down into free chlorine, which is the active disinfectant. Sodium and calcium hypochlorite are chlorine compounds that are in a liquid or solid form. They are used in smaller water systems and require the addition of other chemicals to make them effective disinfectants.
When chlorine is added to water, it reacts with the water molecules to form hypochlorous acid (HOCl) and hypochlorite ion (ClO-). The hypochlorous acid is the active disinfectant that kills or inactivates the microorganisms in the water.
It is a strong oxidizing agent and reacts with the proteins and cell walls of the microorganisms, destroying them. The hypochlorite ion is a weaker oxidizing agent and is responsible for the long-term disinfection of the water. It reacts with the organic material in the water to form compounds that are toxic to microorganisms.

True; before and after a chemical or physical change, the difference in potential bond energy between the reactants and products is known as the intermolecular force strength.
The force that mediates interactions between molecules is known as an intermolecular force (IMF) or secondary force. It includes electromagnetic forces of attraction or repulsion that act between atoms and other types of nearby particles, such as atoms or ions. The forces that hold a molecule together, or intramolecular forces, are stronger than intermolecular forces. For instance, the covalent bond, which involves sharing electron pairs between atoms, is significantly more powerful than the forces that exist between nearby molecules.

how many coulombs of positive charge are contained in the atomic nuclei of this gas?
The total positive charge in the nucleus of any gas is the total number of protons times the total charge contained by one proton. The total number of protons depends on the type of gas, for example, hydrogen, oxygen, chlorine, etc. Each gas has a different number of protons in its nuclei.
To calculate the total positive charge in the atomic nuclei of any gas, find the total number of atoms in the gas. It can be calculated by multiplying Avogadro’s Number with the total amount of gas in moles. If the gas is available in molecules like , then it needs to be multiplied by 2 to calculate the correct number of atoms in the gas. The total number of protons needs to be calculated, which can be done by multiplying the atomic number of gas with the total number of atoms calculated before. Now we can calculate the charge by multiplying the charge on one proton by the total number of protons. A body that has more protons than electrons is said to have a positive charge. We are aware that electrons are negatively charged and protons are positively charged. Consequently, positively charged objects have more protons than electrons.
