Answer:

In a favorable reaction, the free energy of the products is less than the free energy of the reactants.

Explanation:

The free energy of a system is the amount of a system's internal energy that is available to perform work. The different forms of free energy include Gibbs free energy and Helmholtz free energy.

In a system at constant temperature and pressure, the energy that can be converted into work or the amount of usable energy in that system is known as Gibbs free energy. In a system at constant temperature and volume, the energy that can be converted into work is known as Helmholtz free energy.

The change in free energy of a system is the maximum usable energy that is released or absorbed by a system when it goes from the initial state (i.e., all reactants) to the final state (i.e., all products).

In a chemical reaction, some bonds in the reactants are broken by absorbing energy and new bonds are formed in the products by releasing energy. As the reaction proceeds, the free energy of reactants is much greater than the products. As the products are formed, the concentration of reactants decreases and the difference in their free energy also decreases. This chemical reaction will occur until chemical equilibrium is achieved i.e., the free energy of the products and reactants is equal and the difference in their free energy is zero.

In the preceding information section there is a "bohr's diagram" of an atom. Which atom is it?
dsp73
Bohr's atomic model may have not been the accurate atomic model we have in the present, but he helped paved the way for accurate discoveries. His model is also called the planetary model. The nucleus, containing the neutrons and protons are situated at the center of the atom. The electrons are orbiting around the nucleus. The model is illustrated as shown in the attached picture.

Give the number of significant figures in this number: 40.00
Tatiana [17]

A significant figure is every symbol that made the number itself.

In this case, the number 40.00 has four figures but only two of them are significant 40, this is because you haven't got any more decimals than the first zero.

If you have a case with zeros in front, you take to the first non zero digits.

For example, 0.071004 you wold express as 0.071 and those 7, and 1 are the significant ones.

To prepare a 2 M solution of potassium nitrate (KNO3), which quantities must be measured? The mass of the and the volume of the
Olin [163]

Answer:

The mass of the solute and the volume of the solution.

Explanation:

Hello,

In this case, given the formula of molarity:

M=\frac{n_{solute}}{V_{solution}}

In such a way, since the moles could not be directly measured, we must measure the mass of the solute and by using its molar mass, one could compute its moles. Moreover, since the solution is composed by the solvent (typically water) and the solute, we consequently must measure the volume of the solution needed for the preparation of such concentration-known solution. In such a way, we can actually prepare the required solution.

Best regards.

Wade thinks it would be really cool to become a radiologist. Which two skills are important for him to have in order to excel in
zlopas [31]

ANSWER: The two skills that Wade will need to excel in the career of a Radiologist are:

1. Interpersonal skills to talk to patients and help them feel comfortable: This skill important because patients often are afraid of getting detected by a disease. Few patients also fear of getting tested by the heavy and complicated machineries. A radiologist's interpersonal skill will calm the patient and his attendant and will make them feel relieved.

2. Technical skills to know how to use the machinery and equipment needed for the job: Radiologist's primary duty is to operate the machineries in order to diagnose a patient correctly. A radiologist can not afford to be an amateur as he will either not be able to detect a disease or may raise a false alarm of a person having a disease.

Question 2: Phase Changes (14 points) a. Rewrite each of the following equations for phase changes, to include the heat required
lilavasa [31]

Explanation:

(i)  The equilibrium reaction equation will be as follows.

              H_{2}O(l) \rightleftharpoons  H_{2}O(s)

A reaction in which there will be absorption of heat energy is known as endothermic reaction.

A reaction in which there will be release of heat energy is known as exothermic reaction.

As liquid state of water is changing into solid state. So, it means that molecules of water came close to each other. Hence, there will be release of heat this means that reaction is exothermic in nature.

Hence, phase change from liquid to solid will be exothermic in nature.

Latent heat of fusion is defined as the amount of energy necessary to convert 1 gram of a solid into liquid state at its melting point.

So, when solid state of water changes into liquid state then it means energy is absorbed by the molecules of ice due to which they have gained kinetic energy. Hence, they moved away from each other leading to formation of liquid state of water.

Latent heat of freezing of liquid water is 334 J/g.

Specific heat of liquid water is 4.186 J/g ^{o}C

Specific heat of steam is 1.996 kJ/kg/^{o}K

Specific heat of ice is 2.1 kJ/kg/^{o}K

(ii)  The equilibrium reaction equation will be as follows.

              H_{2}O(l) \rightleftharpoons H_{2}O(g)

As liquid state of water is changing into gaseous or vapor state. So, it means molecules of liquid water has gained kinetic energy hence, they colloid more rapidly with each other.

As a result, heat will be absorbed by the liquid state of water. Hence, heat will be absorbed. Therefore, phase change from liquid to gas will be endothermic in nature.

Whereas when gaseous state of water will change into liquid state then heat will be released during this process of condensation. As a result, in that case reaction will be exothermic in nature.
