Potential energy is energy that is stored in an object. It isn't being used at the moment, but is waiting to do work. A good example is to think about a boulder sitting on top of a hill. Just sitting there, the boulder isn't doing anything. But because it is sitting on top of a hill, it has the potential to roll down and do some damage to a car or building below. The energy is stored in that rock because of its size (mass) and the distance it will travel once it starts rolling. Another good example is a rubberband. When you stretch a rubber band, it wants to move back to its original position, and thus you have given it potential energy. As the rubber band is released, potential energy is changed to motion.
Kinetic energy is energy of motion. A rubber band flying through the air has kinetic energy. When you are walking or running your body is exhibiting kinetic energy. This energy is performing work. Other examples of kinetic energy include: legs pump bicycle pedals, lightning snaps trees, cars travel down the street, football players making tackles, and 4-wheelers speeding through the woods.
Potential energy is converted into kinetic energy. As mentioned before, a stretched rubberband can change from having potential to kinetic energy. Another example of this change between kinetic and potential energy can be seen using a yo-yo. Before a yo-yo begins to fall from your hand it has stored energy due to its position. At the top (in your hand) it has its maximum potential energy. As it starts to fall the potential energy begins to be changed into kinetic energy. At the bottom its potential energy has been completely converted into kinetic energy so that it now has its maximum kinetic energy. Another example of the change between kinetic and potential energy is a waterfall. A waterfall has both potential and kinetic energy. The water at the top of a waterfall has stored potential energy. When the water begins to fall, its potential energy is changed into kinetic energy. This change in energy is used in Niagara Falls, Canada to provide electricity to parts of the northeastern United States.

Explanation:

Ionic liquids offer numerous advantages over conventional organic solvents for carrying out organic reactions, Malhotra notes. "In many cases, product recovery is easier, catalysts can be recycled, and the ionic liquids can be reused," he says. "In addition, their thermodynamic and kinetic behavior is different.

Percentage by weight of the NaNO₃, is given by the ratio of the mass of NaNO₃ to the mass of the sample

The percentage by weight of NaNO₃ in the sample is approximately 30.713 %

Reason:

Given parameters are;

Mass of sample of NaBr, NaI, and NaNO₃ mixture = 0.8612 g

Mass of AgNO₃ and AgI formed = 1.0186

Mass of AgCl formed = 0.7125

Required:

Percentage by weight of NaNO₃ in the sample

Solution:

Let A represent NaBr, let B represent NaI, and let C represent NaNO₃, we have;

Equation 1 A + B + C = 0.8612

The addition of AgNO₃, precipitates 1.0186 g mixture of AgBr and AgI, therefore, we have;

[tex]A \cdot\left(\dfrac{Molar \ mass \ of \ AgBr}{Molar \ mass \ of \ NaBr} \right) + B \cdot \left(\dfrac{Molar \ mass \ of \ AgI}{Molar \ mass \ of \ NaI} \right) = 1.0186[/tex]

Molar mass of AgBr = 187.77 g/mol

Molar mass of NaBr = 102.894 g/mol

Molar mass of AgI = 234.77 g/mol

Molar mass of NaI = 149.89 g/mol

Which gives;

Equation 2 [tex]A \cdot\left(\dfrac{187.77}{102.894} \right) + B \cdot \left(\dfrac{234.77}{149.89} \right) = 1.0186[/tex]

The forming of the precipitate by passing the compounds through a stream of chlorine gives;

[tex]A \cdot\left(\dfrac{Molar \ mass \ of \ AgCl}{Molar \ mass \ of \ NaBr} \right) + B \cdot \left(\dfrac{Molar \ mass \ of \ AgCl}{Molar \ mass \ of \ NaI} \right) = 0.7125[/tex]

Molar mass of AgCl = 143.32 g/mol

Therefore, we get;

Equation 3 [tex]A \cdot\left(\dfrac{143.32}{102.894} \right) + B \cdot \left(\dfrac{143.32}{149.89} \right) = 0.7125[/tex]

Solving equation (2), and (3) gives;

A ≈ 0.3252 g, B ≈ 0.2715 g

Plugging in the values of A, and B in equation (1), gives;

0.3252 + 0.2715 + C = 0.8612

C = 0.8612 - (0.3252 + 0.2715) ≈ 0.2645

The mass of NaNO₃ in the mixture, C ≈ 0.2645

[tex]The \ percent \ by \ weight \ of \ NaNO_3 = \dfrac{0.2645}{0.8612} \times 100 \approx \underline{30.713 \%}[/tex]

Answer:

The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in an atom is its mass number minus its atomic number.

The abundance of X-100 is 75 percent, and X-104 has an abundance of 25 percent. The answers are found by solving two equations with two unknowns, which are A plus B equals 100, and 100A plus 104B equals 10,100.

The relative abundance of each isotope in nature

X-100 = 75%

X-104=25%

By dividing the total number of ions identified by the number of ions with a particular m/z m/z m/z ratio, one may determine the relative abundance for each individual ion in the sample.

How can the abundance of two isotopes be determined?

For chemistry problems involving relative abundance, use the following formula:

(M1)(x) + (M2)(1-x) = M (E)

Find the relative abundance of the isotopes if one nitrogen isotope, nitrogen-14, has a mass of 14.003 amu and another, nitrogen-15, has a mass of 15.000 amu.
