Oil is less dense than water. What happens when you mix the two liquids together?

(A) Oil sinks to the bottom of the container.
(B) The two become one smooth mixture.
(C) The oil floats on top of the water.
(D) The water turns to gas inside the oil.

Answers

Answer:

(C) The oil floats on top of the water

Explanation:

If an object/substance is less dense than water it will float on the water.

If an object/substance has the same density as water it will stay submerged in the water, but will not sink to bottom.

If an object/substance is more dense than the water it will sink to the bottom.

what kind of state is a roller coasters are the best use of Newton's laws of motion​

Answers

I am slightly unsure on the question, but if you are asking what kind of "statement" is "roller coasters are the best use of Newton's laws of motion​" then the following should answer your question:

Answer:  

An opinion.

Explanation:  

          In physics, Sir Isaac Newton's first law of motion is known as law of inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.  

          The statement, "Roller coasters are the best use of Newton's laws of motions" is an opinion because it is not based on any evidence, facts, or proof to back it up.

Do you think the black moths would have increased population if the Industrial Revolution didn't occur? Explain your reasoning.

Answers

Answer:

The dark moths were now better camouflaged. As a result, dark moths had a greater chance of reproducing and passing on the alleles that made them dark. This led to a gradual increase in the proportion of dark moths until light moths became very rare in industrial areas. The moth populations in these areas had evolved.

The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism.

How can one separate and collect the solvent from a salt solution​

simple distillation is a method for separating the solvent from a solution. For example water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point then salt. When the solution is heated the water evaporates

Answer:

evaporate

56.75mL of 0.256 HI M reacts with 10.00mL sample of NaOH, what is the molarity of sodium hydroxide?​

Answers

Answer: 1.45M

Explanation:

The definition of molarity is moles/liter.  The neutralization of NaOH with HI is:

HI + NaOH = NaI  + H2O

One mole of HI reacts with 1 mole of NaOH.  We'll assume this is a titration reaction and that the 10.00ml sample of NaOH contains the same number of moles as the 56.75ml of 0.256M HI.

Moles HI:  (0.256 moles/liter)*(0.05675 L) = 0.01453 moles HI

That means we muct have 0.01453 moles NaOH in 10.0ml of NaOH solution.

(0.01453 moles NaOH)/(0.010L) = 1.45 M

==

Another approach is to use the relationship M1V1 = M2V2, which is useful for titrations (M is concentration and V is volume):

We want M2, so rearrange:  M2 = M1V1/V2

M2 = (0.256M)*(56.75ml)/(10.0ml)

M2 = 1.45M

11) What is the relationship between temperature and the speed of sound? Include the concept of molecule
vibration in your explanation.

Answers

Answer:

Temperature is another condition that affects the speed of sound. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly. The speed of sound at room temperature air is 346 meters per second.

Below is a diagram showing a metal being heated. What name is given to particle Y?
Enter your answer

Answers

Answer:

They're called free electrons.

The particle Y marked in the given diagram is electron and surrounding circles indicates metal atom or ions. Free electrons in metal lattice locates at the interstices of the crystal.

What are metals?

Metals are electron rich elements exhibit higher thermal electrical conductivity. Metals are a pool of ions or electrons and therefore they form bonds with electronegative elements by donating electrons.

The interstitial sites of metal crystal lattice are occupied with free electrons and they can be transited to another sites or can be excited to get conductivity.

The electron transition from interstices provide the metal lattice some colors. The region from which an electron is transited is called F-center.

Therefore, the particle Y shown in the interstices of the metal lattice is electron.

why do atoms emit light energy according to the bohr model?

Answers

Answer: According to the Bohr model, atoms emit light because excited electrons are returning to lower energy states, emitting the energy difference. This energy always has a specific wavelength because the electrons can only exist in set orbits. ... An emission spectrum is the frequencies of light emitted from an atom.

Explanation:

Atoms emit light energy because electrons transit between energy levels by absorbing energy and relaxing by emission of radiation.

What is Bohr's model of atom?

According to Bohr model of atom the electrons are revolving around the nucleus through the circular paths of fixed energies. These circular paths are called orbits.

Using this model the momentum and velocity of an electron  and the atomic radius can be determined. Bohr, states the electrons are able to transit between these energy level and the energy difference between the two energy levels will be equal to the energy of a photo  absorbed by the atom.

Electrons excite to higher energy level by by absorbing energy and they cant stay there for long while and relax back to the ground state by emitting a the radiation which is complementary wavelength to the absorbed one. That's why the atoms emit light.

Using the periodic table, explain which pair of the following gases have the most similar properties and why. Nitrogen (N), Fluorine (F), Neon (Ne), Krypton (Kr), and Oxygen (O).

Answers

Answer:  Neon (Ne) and Krypton (Kr)

Explanation:

Elements that belong to the same group of the periodic table (column) have similar properties. This is because elements of the same group have the same amount of valence electrons. This means that chemically and especially in a chemical reaction (or lack thereof), they will behave similarly.

Neon and Krypton are the only two gases in the list given that belong to the same group of the periodic table (Group 18 - Noble Gases) and as such have similar properties.

Similar Properties of Neon and Krypton:

- Both have 8 valence electrons - They both are very stable and almost unreactive- Both are gases at RTP-Both are odorless, colorless, and tasteless until interaction with an electrical charge.
