Answers

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.

When the friction slider was increased to about ¼, the skater completed ___ loops before failing?

Answers

When the friction slider was increased to about ¼, the skater completed less loops before failing?

What is friction?

We can define the friction that is acting on the object as the kind of force that is acting on an object so as to reduce the speed of the object. As such, we can see that we have a situation whereby we have an object that is in motion.

If an object is in motion, we know that the force that tries to slow down the object is the force of the friction that is acting on the object that is in question. The skater is also under the action of the force of friction and this is the force that is attempting to slow the skater down as described above.

2) The molar mass of the gaseous compound is 0.416 g/mol.

To draw a correct Lewis structure for XeI2, we need to first count the number of valence electrons in the molecule. Xenon is a noble gas and has 8 valence electrons, while iodine has 7 valence electrons for a total of 23 valence electrons. To satisfy the octet rule and put a 0 formal charge on all atoms, we can use the following Lewis structure:

To find the molar mass of the gaseous compound, we can use the ideal gas law:

M = dRT/P

Where M is the molar mass, d is the density, R is the ideal gas constant, T is the temperature, and P is the pressure.

Given that the density of the gas is 0.3876 grams/142 mL = 0.002736 grams/mL, the temperature is 150 + 273 = 423 K, the pressure is 775 torr = 775/760 atm = 1.0132 atm, and the ideal gas constant is 0.08206 L·atm/mol·K.

We can calculate the molar mass as follows:

M = (0.002736 g/mL) * (0.08206 L·atm/mol·K / (1.0132 atm)) * (423 K)

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?

Answers

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.
