how do electrostatic forces affect the electrons in an atom?​

Answer:

Highest wavelength : radio waves

So lowest energy: radio waves

Hence order is:

radio waves < microwaves < IR waves < visible light < ultraviolet radiation < X-rays < gamma rays

Answer:

The concept of the atom (Greek: atomos, "indivisible"), an indivisible particle of matter, goes back to ancient Greece and a man named Democritus, a rival of Aristotle. Democritus held that all matter could be subdivided only until some finite particle was reached.Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that all matter is made of atoms, which are indivisible.Atomic theory established that all matter is made of tiny particles, a discovery that led to amazing scientific breakthroughs in areas from modern chemistry to nuclear energy.Atomic models are important because, they help us visualize the interior of atoms and molecules, and thereby predicting properties of matter.This atomic model has changed over time. Scientists used the model to make predictions. Sometimes the results of their experiments were a surprise and they did not fit with the existing model. Scientists changed the model so that it could explain the new evidence.Atomic theory originated as a philosophical concept in ancient India and Greece. The word "atom" comes from the ancient Greek word atomos, which means indivisible. According to atomism, matter consists of discrete particles. However, the theory was one of many explanations for matter and wasn't based on empirical dataEverything is composed of atoms, which are the indivisible building blocks of matter and cannot be destroyed. All atoms of an element are identical. The atoms of different elements vary in size and mass. Compounds are produced through different whole-number combinations of atoms.Dalton's atomic theory suggested that the atom was indivisible and indestructible. But the discovery of two fundamental particles (electrons and protons) inside the atom, led to the failure of this aspect of Daltons atomic theory.

The ionization constant from the reaction as shown in the calculation is 5.8.

The term ionization constant refers to the extent to which the acid is ionized in solution. It is calculated from;

Ka = [H3O^+] [Cl]/[HCl]

Thus when we substitute the values;

Ka = 13.3 * 7.4/ 16.9

Ka = 5.8

Explanation:

Wavelengths of absorbed or emitted photons causes lines in a line spectrum.

Spectral lines are produced by transitions of electrons within atoms. As the electrons move closer or farther from the nucleus of an atom, energy is released in the form of light is emitted.

So we can conclude that Wavelengths of absorbed or emitted photons causes lines in a line spectrum.

Answer:

Increases

Explanation:

The general effect we see as temperature increases is that rate of dissolution of a solid solute increases,

Therefore, we can say that :

Temperature ∝ Rate of dissolution

After 160 years, the activity level of the sample will be 0.5 curies.

Half life of any radioactive waste is the half decay of that product.

The formula is [tex]\dfrac{\lambda }{\lambda_1} = 2^\dfrac{a}{b}[/tex]

Where, λ is 4 cruies

λ1 is 0.5 cruies

b = 40 years

Putting the values in the equation

[tex]\dfrac{4}{0.5} = 2^\dfrac{a}{40}\\\\\\\dfrac{a}{40} = 4\\ = 160 years[/tex]

Thus, the correct option is 160 years.

Answer:

Explanation:

You would have to add up the atomic masses of all the compounds in the compound, making sure you include how many molecules of each are in the compound

For example, in CuSOA we have 1 molecule of Cu and S, as 4 molecules of O

The atomic masses are as follows:

Cu = 63.55 u

S = 32.065 u

O = 15.99 units

This is how we would add it up:

(Atomic mass of Cu) + (Atomic mass of S) + 4(Atomic Mass of O)

(63.55) + (32.065) + 4(15.99)

(63.55) + (32.065) + 63.96

= 159.575 u

Since the reaction is not spontaneous at room temperature, the ΔH will be positive.

They are reactions that require no additional effort in order for them to take place under certain conditions.

For spontaneous reactions, the change in the energy of the system, otherwise known as ΔH, is always negative. On the other hand, reactions with positive ΔH are non-spontaneous.

Answer:

Look at the pH level.

Explanation:

The best way to determine whether a solution is acidic or basic is to look at its pH level. The pH of a solution is a number between 0 and 14.

If a solution has a pH of less than 7, then it is acidic.

If a solution has a pH of 7, then it is neutral.

If a solution has a pH of greater than 7, then it is basic.
