How is the number of unpaired valance electrons in an atom related to the number of bonds that the atom can form?
TiliK225 [7]
It is the same amount. For example, Carbon has 4 electrons. Putting those 4 electrons in a Lewis Dot Structure will show that they are not paired, so 4 is the number of bonds Carbon can make.

Calculate the molarity of 0.289 moles of FeC13 dissolved in 120 ml of solution
yanalaym [24]

Answer:

2.41 M

Explanation:

The molarity is the moles of FeCl3 over the liters of solution. Since you're given mL you need to change it to L which is 0.12 L. 0.289 divided by 0.12 is your answer

How are the energy and wavelength of electromag<br> netic radiation related?
tia_tia [17]

Answer:

Electromagnetic radiation is a form of energy that is produced by oscillating electric and magnetic disturbance, or by the movement of electrically charged particles traveling through a vacuum or matter. The electric and magnetic fields come at right angles to each other and combined wave moves perpendicular to both magnetic and electric oscillating fields thus the disturbance. Electron radiation is released as photons, which are bundles of light energy that travel at the speed of light as quantized harmonic waves. This energy is then grouped into categories based on its wavelength into the electromagnetic spectrum. These electric and magnetic waves travel perpendicular to each other and have certain characteristics, including amplitude, wavelength, and frequency.

General Properties of all electromagnetic radiation:

Electromagnetic radiation can travel through empty space. Most other types of waves must travel through some sort of substance. For example, sound waves need either a gas, solid, or liquid to pass through in order to be heard.

The speed of light is always a constant. (Speed of light : 2.99792458 x 108 m s-1)

Wavelengths are measured between the distances of either crests or troughs. It is usually characterized by the Greek symbol  λ .

Hi!


The reason for reviewing and replicating work of other scientists is influenced by two factors listed in the answer:

1. An experiment may have had errors that the scientist did not recognize. <u>(unintentional) </u>

2. The results of individual scientists may be influenced by bias. <u>(intentional)</u>

<em>Personal motivations may often influence a scientist to manipulate the results to best suit his/her hypothesis, consequently leading to scientific fraud. </em>

While other options listed are elements of the scientific method, they are not the reasons behind the review and replication of a scientist's work by others.
