What is the reason water is a liquid at normal earth conditions when it should be a gas

Answers

Actually, from the phase diagram, water should exist as liquid at normal conditions. At a pressure of 1.0 atm and 25 degrees Celsius, water exist as a liquid not a gas. Only when the temperature reaches 100 and more, it exist as gas.

At standard pressure, how do the boiling point and the freezing point of NaCl(aq) compare to the boiling point and the freezing point of H2O(image)?

Answers

The boiling point of Sodium chloride(aq) is higher and the freezing point of Sodium chloride(aq) is lower.

What is the boiling point?

The boiling point is the temperature at which the pressure exerted by the surroundings upon a liquid is equal to the pressure exerted by the vapour of the liquid.

Usually, in this context, you would be referring to the boiling and freezing point of a Sodium chloride solution compared to pure H2O.

The boiling point of pure water is 100 degrees Celcius (212 Fahrenheit), and the freezing/melting point is below 0 degrees Celcius (32 Fahrenheit). For a solution, the boiling point is raised and the melting point is lowered.

This means that water will stay liquid for an increased range of temperature. Depending on the amount of Sodium chloride solute in the water, the boiling and melting points may change a few degrees.

Which of the following best describes how chemical changes differ from physical changes?A. Physical changes produce no new substances and chemical changes do.
B. Physical changes always involve the formation of a gas while chemical changes may not.
C. Physical changes can occur inside or outside the substance; chemical changes always occur outside.
D. Physical changes involve a change of state; chemical changes involve a change of shape.

Answers

Answer:

A is the answer.

Explanation:

Physical changes do not change the substance's composition but just the outside qualities. However, chemical changes change the composition of the substance and it's chemical properties.

The basic points in Lewis and Langmuir theory of electrovalency

Answers

The correct answer for the question that is being presented above is this one: "Electrovalency is characterized with the transferring of one or more electrons from one atom to another together with the formation of ions and as well as the number of positive and negative charges.

The Lewis and Langmuir theory of electrovalency (and as well as Kossel's) is dealing with Ionic bonds.

Lewis: electron-pair sharing, octet rule, Lewis Symbols or StructureLangmuir: introduced term "covalent" bond, and popularized Lewis's ideas

The Lewis-Langmuir electron-pair or covalent bond is referred as the homopolar bond, where the complete transfer of electrons give rise to ionic, or electrovalent bond (1) through attraction of opposite charges.

Describe 3 ways that you could change the rate of the reaction based on principles that effect rates of reactions.

Answers

Three ways to change the rate of a reaction are by increasing the concentration of reactants, changing the temperature, and adding a catalyst.

Three ways to change the rate of a reaction:

Increasing the concentration of reactants: This increases the collision frequency between particles, leading to a higher reaction rate. For example, in the reaction between hydrogen and iodine to form hydrogen iodide, increasing the concentration of hydrogen and iodine will speed up the reaction.
Changing the temperature: Higher temperatures increase the kinetic energy of particles, making them move faster and collide more frequently. This results in a faster reaction rate. Using an example, raising the temperature of the reaction between magnesium and hydrochloric acid will speed up the rate of reaction.
Adding a catalyst: Catalysts are substances that speed up reactions by providing an alternative reaction pathway with lower activation energy. For instance, adding an enzyme catalyst like amylase to the reaction between starch and iodine will increase the reaction rate.

The three main ways to change the rate of reaction based on principles that affect rates of reactions are concentration, temperature, and catalysts .let us describe them one by one further.

Three ways to change the rate of a chemical reaction are:

Concentration Change: Increasing the concentration of reactants usually speeds up the reaction. This is due to more frequent collisions between particles, increasing the likelihood of successful collisions leading to product formation.
Temperature Change: Raising the temperature accelerates reactions by providing more energy to reactant particles, increasing their kinetic energy, and promoting successful collisions.
Catalysts: Adding a catalyst lowers the activation energy required for the reaction, making it easier for reactants to transform into products. Catalysts provide an alternate reaction pathway, allowing reactions to occur at lower energy levels and faster rates.
