What is a trait and where does an organism get its traits from?

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.

Based on the stoichiometry of the reaction, If the mass of sodium azide used was far greater than 1424 g, the volume of nitrogen gas produced will be far greater than 736 L.

However, If the mass of sodium azide used was far less than 1424 g, the volume of nitrogen gas produced will be far less than 736 L.

Sodium azide is the chemical found in automobile airbags.

Automotive air bags inflate when an electrical charge triggered by automobile impact causes sodium azide, NaN3, to rapidly decompose to its component elements, nitrogen gas and sodium

The equation of the reaction is given below:

According to the equation of reaction, 2 moles of sodium azide produces 3 moles of nitrogen gas.

1 mole of Nitrogen gas has a volume of 22.4 L

Molar mass of sodium azide is 65 g

Moles of sodium azide in 1424 g = 1424/65 = 21.9077 moles

21.9077 moles of sodium azide will produce 21.9077 * 3/2 moles of nitrogen gas = 32.86 moles of nitrogen gas

32.86 moles of nitrogen gas will occupy a volume of 32.86 * 22.4 = 736 L

If the mass of sodium azide used was far greater than 1424 g, the volume of nitrogen gas produced will be far greater than 736 L.

If the mass of sodium azide used was far less than 1424 g, the volume of nitrogen gas produced will be far less than 736 L.

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

See  attached image.  The last problem was a challenge, but I can guarantee that it is the teacher's fault if I'm not correct.

Explanation:

On the attachment.  Remember that all gasses occupy 22.4 liters at STP.  It is a good constant to memorize.  It often comes up in chemical calculations, and you can also use it at parties if you want to annoy anyone.  Also, depend on the units to help you decide how to do a calculation.  moles/liter or liters/mole:  it makes a difference in whether you multiply or divide.  Use the operation that cancels the units you don't want and leaves the target unit.

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: 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

From what we know, we can confirm that doing this may dirty and cause harm to your 40x lens.

Oil immersion is a technique that can be quite handy when attempting to view hard-to-see specimens. However, This should be done only with lenses that are made specifically for this, so revolving the nosepiece in the wrong direction will expose the 40x lens to the oil, for which it is not designed, and may cause harm to the equipment.

Therefore, we can confirm that the 40x lens could get dirty with oil if you move the revolving nosepiece in the wrong direction after viewing it under oil immersion.

Answer:

There is an intimate connection between the atomic structure of an atom and its spectral characteristics. Atoms of individual elements emit light at only specific wavelengths, producing a line spectrum rather than the continuous spectrum of all wavelengths produced by a hot object.
