Convert the answer above to Kelvin

Answer: 5.747 * 10^14 Hz

Explanation:

Convert 522nm to m = 522 * 10^-9 m (since 1nm=10^-9m)

If c = wavelength * frequency, where c is the speed of light (3.0 * 10^8 m/s), then you can manipulate the equation to solve for frequency (f).

f = c / wavelength

Plug in the given numbers:

f = (3.0 * 10^8) / (10^-9)

f = 5.747 * 10^14 Hz

Answer:

The wavelength λ is the distance between successive peaks in a wave. The frequency f of a wave is the number of complete waves that pass a point in a given time. where c is the speed of light. In your case, λ = 522 nm = 522 × 10⁻⁹ m and c = 2.998 × 10⁸ m·s⁻¹

Answer:

Overflowing waste containers can lead to drips of potentially hazardous chemicals down the sides. Chemicals and their vapors need room to expand in case of increased temperatures.

The pressure in tank X is greater than that in tank Y because the number of moles or mass of argon gas in Tank X is greater than the number of moles or mass of nitrogen gas in Tank Y.

The pressure of a gas is the force that molecules of the gas exert per unit area of the walls of their container due the collisions of the gas molecules with themselves and with the walls of their contain.

The pressure of a gas is related to the volume (V), temperature (T) and number of moles (n) of the gas by the formula:

where;

Since volume, temperature and R is constant for the two gases, the pressure difference will be determined by the number of moles of each gas.

Number of moles of a gas is proportional to the mass of the gas present.

Therefore, the best explanation as to why the pressure in tank X is greater than that in tank Y is that the number of moles or mass of argon gas in Tank X is greater than the number of moles or mass of nitrogen gas in Tank Y.

Answer:

Because it exhibits metallic qualities, conducts electricity, and heats well, sodium is classified as a metal. Further, its structure is held together by so-called metallic bondings, which means that each atom contributes some electrons to the metal's electron cloud.

Explanation:

Answer: Igneous rock is formed by the melting and cooling of magma or lava.

Inside of Earth, magma slowly cools, creating rock with an irregular or rough texture and large crystals. Magma cooling inside Earth creates intrusive igneous rock.

Outside of Earth, lava cools very quickly, creating rock with a fine, grainy look or texture and small crystals. Lava cooling outside of Earth creates extrusive igneous rock.

Examples: granite, basalt, and pumice

Particles at the same temperature have the same average kinetic energy, so argon and nitrogen, which are at 20°C, are the gases with the lowest average kinetic energy. Nitrogen and helium, at 100°C, have the highest average kinetic energy because they have the highest temperature.

The solubility of the alcohols in water increases as the number of hydrogen bonds they can form with water increases.

A solution consists of a solute and a solvent. See the saltwater example to understand the difference between the two. Water is a solvent because it is a substance used to dissolve solutes.

Salt is a solute because it is a substance dissolved in water. Solvents tend to be more abundant in solution. Solution can exist in the form of all three states of matter.

Solubility is the ability of a solute to dissolve in a solvent to form a solution. This is the nature of dissolving sugar molecules and the like in coffee. Water is known as the "universal solvent" because it can dissolve most substances, but there are some exceptions.

Solubility forms new bonds between solute and solvent molecules. It is the maximum concentration of a solute that will dissolve in a solvent of known concentration at a given temperature.

Therefore, The solubility of the alcohols in water increases as the number of hydrogen bonds they can form with water increases.

Answer:

Its A and C

Explanation:

A mixture of oil and water is:

Heterogeneous

immiscible

The water molecules attract each other, and the oil molecules stick together. That causes oil and water to form two separate layers. Water molecules pack closer together, so they sink to the bottom, leaving oil sitting on top of the water. The mixture can be called as Emulsion. It is an immiscible liquid and the mixture is heterogeneous as oil floats on top of water surface but do not mix with it.

Thus, correct options are Heterogeneous and immiscible.

Answer:

I. Increasing pressure will allow more frequent successful collision between particles due to the particles being closer together.

II. Rate of reaction increases due to more products being made; as increased pressure favours the exothermic side of the equilibrium.

III. Increasing temperature provides particles lots of (Kinetic) energy, for more frequent successful collision due to the particles moving at a faster rate than before. However, favouring the endothermic side of the equilibrium due to lots of energy required to break and form new bonds.

IV. Rate of reaction increases due to increase temperature favouring both directions of the equilibrium - causing products to form faster.

Phosgene is extremely toxic by acute (short-term) inhalation exposure. Severe respiratory effects, including pulmonary edema, pulmonary emphysema, and death have been reported in humans.

I. If the pressure of gaseous reactants is increased, there are more reactant particles for a given volume. There will be more collisions and so the reaction rate is increased. The higher the pressure of reactants, the faster the rate of a reaction will be.

II. Increasing the pressure on a gas reaction shifts the position of equilibrium towards the side with fewer moles of gas molecules.

III. Increasing temperature provides particles lots of (Kinetic) energy, for more frequent successful collision due to the particles moving at a faster rate than before. However, favouring the endothermic side of the equilibrium due to lots of energy required to break and form new bonds.

IV. If the temperature is increased, the position of equilibrium moves in the direction of the endothermic reaction. if the temperature is reduced, the position of equilibrium moves in the direction of the exothermic reaction.
