What is ppm ?
Reduction, which involves the exchange of electrons between species, is the process of gaining electrons or reducing an element's oxidation state in a chemical reaction. When the chemical reaction known as reduction occurs, the number of electrons that are bound to a single atom or a group of related atoms rises.

the accepted density of a certain material is 7.44 g/cm^3. A student measures the density of the same material as 7.30 g/cm3. What is the percentage error of the measurement?
The percentage error of the measurement, given that the accepted measurement is 7.44 g/cm³, is 1.88%
How do I determine the percentage error?First, we shall determine the absolut error. This can be obtained as follow:
Accepted value = 7.44 g/cm³Measured value = 7.30 g/cm³Absolute error = ?Absolute error = accepted value - measured value
Absolute error = 7.44 - 7.30
Absolute error = 0.14 g/cm³
Haven obtained the absolute error, we shall determine the percentage error. Details below:
Absolute error = 0.14 g/cm³Accepted value = 7.44 g/cm³Percentage error =?Percentage error = (Absolute error / accepted value) × 100
Percentage error = (0.14 / 7.44) × 100

when the electron moves closer to the nucleus, the energy increases to overcome the positive and negative attractions.
Yes, this is correct. When an electron moves closer to the nucleus, the electrical attraction between the electron and the nucleus increases and the electron must expend more energy to stay in that position. This increase in energy is due to the increased force of attraction between the electron and the nucleus.
The Effect of Electrostatic Attraction on Electron EnergyThe interaction between electrons and the nuclei of atoms is the basis of chemistry. This interaction is due to the attractive force of electric charge, which is known as electrostatic attraction. This force can be felt when an electrically charged object approaches another electrically charged object.
The electrostatic attraction between an electron and the nucleus of an atom depends on the electric charge and the distance between them. The more charged the electron is, the stronger the attraction. The closer the electron is to the nucleus, the stronger the attraction.
This means that when an electron moves toward the nucleus, the electrostatic attraction between them increases, requiring the electron to expend more energy to stay there. This means that when an electron moves closer to the nucleus, the energy of the electron increases to overcome the positive and negative attraction.

Oxygen and chlorine gas are mixed in a container with partial pressures of 3040 mmHg

What is the TOTAL pressure inside the container in atm? *Don't forget to convert: 760mmHg
= latm*
Type your answer...
A mixture of oxygen and chlorine gas with a partial pressure of 3040 mmHg and 1.63 atm respectively will have a total pressure of 5.55 atm.
Partial pressure of gas mixturesAccording to Dalton's law of partial pressure, when a gas contains a mixture of gases, the total pressure of the gas mixture is the sum of the individual gas pressure.
This law can be mathematically expressed as:
P (total) = P ₁ + P ₂ + P ₃ + ......
Where P is the pressure of gas and 1, 2, 3, etc., represent the gases respectively.
In this case, the pressure of oxygen is 3040 mmHg. We first need to convert this to atm.
1 mmHg = 0.0013 atm
Thus, 3040 mmHG = 3040 x 0.0013
= 3.952 atm
The pressure of chlorine is 1.63 atm. Thus, the total pressure of the gas mixture would be:
P (total) = P oxygen + P chlorine
= 3.92 + 1.63
= 5.55 atm
In other words, the total pressure inside the container in atm would be 5.55 atm.
