What are the balanced chemical equations for Hydrochloric acid and potassium hydroxide?

Which statement about the reaction is correct?

Goshia [24]

The reactions based on the absorption and release of the energy are called endothermic and exothermic reactions. The reaction is exothermic.

<h3>What is an exothermic reaction?</h3>

Exothermic reactions are the reaction in which the reactant produces products that release energy from the system to the surroundings. In the reaction bond energy of the reactant is less than the product.

Energy from the system is released in the form of heat, sound, light and electricity. The weak bonds of the compounds are replaced with stronger ones and the standard enthalpy of the reaction is negative.

Therefore, option c. reaction is exothermic is correct.

Use your understanding of the ideal gas law to identify the correct relationships among the variables. Pressure is . Temperature

MAXImum [283]

Answer:

Pressure is inversely proportional to the volume of a gas at constant temperature and number of moles

Temperature is directly proportional to volume at constant pressure and number of moles

Volume is directly proportional to the number of moles of a gas at constant temperature and pressure

Explanation:

The ideal gas law is derived from a combination of the Boyle's, Charles' and Avogadro's law of gases.

Boyle's law states that at constant temperature, the volume of a given mass of gas (number of moles of gas is constant) is inversely proportional to the pressure exerted by the gas.

V ∝ 1/P (at constant n, T)

Charles'law states that at constant pressure, the volume of a given mass of gas (constant amount, n) is directly proportional to the temperature of the gas; V ∝ T (at constant n, P)

Avogadro’s law states that at constant temperature and pressure, the volume of a given mass of gas is directly proportional to the number of moles of gas present; V ∝ n(at constant T, P)

Combining the three equations gives the following relationship: V ∝ nT/P

By inserting a proportionality constant called the molar gas constant, R, in the relationship above, the ideal gas equation is derived as follows:

V = nRT/P or PV = nRT

<h3>What is a Chemical Reaction ?</h3>

Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products.

Substances are either chemical elements or compounds.

A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

Chemical reactions are an integral part of technology, of culture, and indeed of life itself.

The product that is formed is shown in the figure , Option A is the correct answer , and the highlighted carbons shown corresponds to the carbons from diethyl malonate.
