Explanation:

Answer:

Copy and paste "Electromagnetic waves are categorized according to their frequency f or, equivalently, according to their wavelength λ = c/f.  Visible light has a wavelength range from ~400 nm to ~700 nm.  Violet light has a wavelength of ~400 nm, and a frequency of ~7.5*1014 Hz.  Red light has a wavelength of ~700 nm, and a frequency of ~4.3*1014 Hz." into google, and the correct website pops up as the first result.

Explanation:

I tried to link the website that I use to convert wavelengths and frequencies into types of light, but it deleted my answer, so I guess we're doing it this way. As for converting the wavelength to energy, the same principles apply as before:

Frequency: ν       Wavelength: λ       Energy: E       Speed of light: C (3.00e8)       Planck's Constant: h (6.626e-34)

ν -> λ    λ = C/ν

λ -> ν    ν = C/λ

For either of these equations, wavelength must be converted to meters or nanometers, depending on the equation.

For ν -> λ, after doing the equation, convert the wavelength into nanometers by dividing by 1e-9.

For converting λ -> ν, convert the wavelength into meters by multiplying by 1e-9.

For energy: E = hν = hc/λ

Answer:

Hydrogen is the smallest chemical element. It has one proton and one electron, making it neutral. However, the ions of hydrogen atom are charged species. Thus, the key difference between hydrogen atom and hydrogen ion is that the hydrogen atom is neutral whereas hydrogen ion carries a charge.

Answer:

A normal hydrogen (H) atom does not have any neutrons in its tiny nucleus. That tiny little atom (the tiniest of all) has only one electron and one proton. You can take away the electron and make an ion, but you can't take away any neutrons.

Explanation:

A. 2s is incorrect, the right arrow should be pointing downwards.

B. In 2p, the last box has 3 arrows. This is invalid. Each box can only store 2 arrows(electrons).  The last arrow should be moved to a 3p orbital (new box).

C. In this one, the arrows switched directions (left is down and right is up). You could fix each box or just the last one (in 3p) to point downwards.

Answer:

True

Explanation:

Volume is measured in "cubic" units. The volume of a figure is the number of cubes required to fill it completely, like blocks in a box. Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed.

Answer: Atoms aren't entirely empty space

Explanation:

Rutherford did his scatter experiment to disprove Thomson's Plum Pudding Model. Rutherford shot helium nuclei at a sheet of gold and expected the particles to all go straight through to a sensor. The reason he expected this was because Thomson said that atoms are mostly made of empty space. Not all the particles went through the gold sheet, a lot of them actually reflected back to him. This meant that atoms aren't entirely empty space and something had to deflect the helium nuclei

Answer:

longer, greater;

Explanation:

This is more of a physics question. Refer to any notes you might have on simple machines. In short though, a wrench with a longer handle requires less force to be used than a wrench with a short handle. As a result it has more mechanical advantage.

The answer "shorter, less " could also be correct but it's listed twice so I wouldn't pick it.

Electrons in pi bonds can spread over a group of atoms. This is what is meant by delocalization of a pi bonded network.

There are two kinds of bonds in chemistry, these are;

Sigma bonds are formed by end to end overlap of atomic orbitals while pi bonds are formed by side by side overlap of atomic orbitals.

Sometimes, pi orbitals are well oriented in such a way that electrons are spread over the pi orbitals of several atoms. For instance, in benzene, there are six pi electrons that are spread over the six carbon atoms in benzene. This is what is meant by delocalization.

Delocalization can only occur when there is are conjugated double bond. This is why delocalization is common in many aromatic compounds. Some inorganic ions such as CO3^2- also have delocalized pi electrons.

Explanation:

The mass of a cube of magnesium : 322.2 g

Density is a quantity derived from the mass and volume

Density is the ratio of mass per unit volume

The unit of density can be expressed in g / cm³ or kg / m³

Density formula:

[tex]\large{\boxed {\bold {\rho~=~ \frac {m} {V}}}}[/tex]

ρ = density , g / ml

m = mass , g

v = volume , ml

mass of aluminum = 500 g

density of aluminium = 2.7 g/ml

there is data that needs to be added⇒ density of magnesium : 1.74 g/ml

the same dimensions = the same volume

[tex]\tt V=\dfrac{m}{\rho}\\\\V=\dfrac{500}{2.7}=185.19~ml[/tex]

V magnesium = V aluminum

[tex]\tt m=\rho\times V\\\\m=1.74\times 185.19\\\\m=\boxed{\bold{322.2~g}}[/tex]

The cube of same dimensions of magnesium and aluminum have same volume. The mass of cube of magnesium has been 321.85 grams.

The density has been given as the mass of substance per unit volume. The density of aluminum cube has mass 500 grams, and density 2.7 g/mL. The volume of the aluminum cube has been:

[tex]\rm Density=\dfrac{Mass}{Volume}\\\\2.7\;g/mL=\dfrac{500\;g}{Volume} \\\\Volume=185.18\;mL[/tex]

The volume of the magnesium and aluminum cube has been the same. The density of magnesium has been 1.735 g/mL. Thus, the mass of Mg cube has been given as:

[tex]\rm 1.738\;g/mL=\dfrac{Mass}{185.18\;mL}\\\\ Mass=321.85\;g[/tex]

Thus, the mass of magnesium cube has been 321.85 grams.
