The extra conversion of concentration of reactant and product should be zero in order to attaining equlibrium state.

Chemical equilibrium refers to the state in which both the reactants and products are present in equal concentrations or amount. In equlibrium, same amount of reactant is converted into product and product into reactant.

So we can conclude that the extra conversion of concentration of reactant and product should be zero in order to attaining equlibrium state.

Given the following equation; Cu + 2AgNO3 = Cu(NO3)2 + 2Ag, 48.97 grams of Cu are needed to react with 262g of AgNO3.

The mass of a substance can be calculated using the following steps:

Cu + 2AgNO3 = Cu(NO3)2 + 2Ag

1 mole of Cu react with 2 moles of AgNO3

moles of AgNO3 = 262g/169.87g/mol = 1.54mol

1.54 moles of AgNO3 will react with 0.77 moles of Cu.

mass of Cu = 0.77 × 63.5 = 48.97g

Therefore, given the following equation; Cu + 2AgNO3 = Cu(NO3)2 + 2Ag, 48.97 grams of Cu are needed to react with 262g of AgNO3.

The amount of heat transferred in and out of the system is measured by calorimetry. The thermometer in the calorimeter is used to measure the temperature.

The thermometer (A) is a device used to measure the final and the initial temperature of the water or any other liquid in a system. A metal vessel is a place where the reaction mixture is present.

In-vessel (B), water, and metal are placed before the beginning of the experiment. The styrofoam cup or the outer metal vessel (C) insulates the instrument, from regulating the heat transformation.

Therefore, part A measures the temperature of the reaction mixture.

Elecetronegativity will affect the replacement reactions as it attracts the bonded electrons towards itself.

Replacement reactions are those reactions in which replacement of any one element from any compound is done by any other element.

Electronegativity is the attracting power of any element to hold the bonded electron towards itself so that they will bear a partial negative charge on itself. If in any reaction replacement of anion is required and any compound have more electronegative element which bounded the bonded electron strictly and will not allow the formation of anion then it affects the activity of the reaction.

Hence electronegativity affect the replacement reactions.

Considering the definition of chemical equation, the equilibrium system described by this equation has 4 reactant molecules and 2 product gas molecules.

A chemical equation is a symbolic description used to describe the identities and relative quantities of the reactants and products involved in a chemical reaction.

The information contained in the chemical equation allows us to determine the substances that are transformed or modified in a reaction, called reactants or reagents, and the new substances that originate in a chemical reaction, called products.

The chemical equation must comply with the Law of conservation of matter. That is, the equation must indicate that the number of atoms of the reactants and products is equal on both sides of the reaction and that the charges are also equal.

In this case you know:

N₂ + 3 H₂ ⇄ 2 NH₃

You can observe that the number of H₂ is 3, while the number of N₂ is 1.

The number of molecules on the reactant side is the sum of hydrogen and nitrogen molecules. Then, the total number of reactant molecule is 4.

The number of product molecules are only the number of NH₃. Then, the number of product molecules are 2.

Finally, the equilibrium system described by this equation has 4 reactant molecules and 2 product gas molecules.

. The error due to weighing the solute can be minimised by using concentrated stock solution that requires large quantities of solute. 2. We can prepare working standards of different concentrations by diluting the stock solution which is more efficient since consistency is maintained

3. Some of the concentrated solutions are more stable and are less likely to support microbial growth than working standards used in the experiments.

I suppose that you want to produce a 0.25 M solution of KCl

You do not want tp produce 0.25 mol of KCl.

Molar mass KCl = 39.1 + 35.45 = 74.55 g/mol

Mass of 0.25 mol KCl = 0.25 mol * 74.55 g/mol =18.64 g

To produce a 0.25 M solution of KCl = 18.64 g would require a solution volume of 1.0 L or 1000 mL

You have only 5.00 g ( NOT 5.00 gm) of KCl

Volume of solution required = 5 g / 18.64 g * 1000 mL = 268 mL solution

You dissolve the 5 g KCl in some water and then make up the final solution volume to 268 mL

This does NOT mean that you dissolve the 5 g KCl in 268 mL water .

Many policies are established to control air pollution like Tradable Permit System, Corrective Tax, Command-and-Control Policy, and Corrective Subsidy.

A corrective subsidy is a policy that encourages people to plant trees. Command-and-Control Policy or the regulation policy limits the emission of the particles that affect and harms the air and mandates the use of emissions-reducing technology.

Corrective Tax policy discourages negative effect behavior and imposes Pigovian tax that helps in achieving optimal pollutants. Tradable Permit System allows the figuring of the individual pollution emission.

2) A. increases

3) A. increases

hope this helps :)

A solution is defined as the homogeneous mixture which contain one or more solutes in a solvent. The factors which affect the solubility are temperature and pressure. Here individual salt crystals dissolve faster.

The maximum amount of solute which can dissolve in a given quantity of the solvent at a certain temperature is defined as the solubility. It is defined as the property exhibited by a material to dissolve in a given solvent.

The powdered salt found to dissolves faster in a solvent than the salt of larger size. The rate of dissolving is affected by the size of the solute. The faster the solute dissolves if its size is smaller. So the  individual salt crystals dissolves faster.

In most cases, generally the solubility found to decrease with the increase of temperature. When the temperature increases, the kinetic energy of the molecules increases and thereby decreases the intermolecular force of attraction. The increase in the process of agitation decreases the solubility.
