Which phrase describes a metamorphic rock?
formed from a volcano
was once buried underground
formed from evaporating water
contains minerals that have not changed

Answer:

Elements to the left of the line are considered metals. Elements just to the right of the line exhibit properties of both metals and nonmetals and are termed metalloids or semimetals. Elements to the far right of the periodic table are nonmetals. The exception is hydrogen (H), the first element on the periodic table.

Explanation:

Answer:

looking at its metallic luster

Explanation:

Elements may be classified as either metals or nonmetals based on their properties. Much of the time, you can tell an element is a metal simply by looking at its metallic luster, but this isn't the only distinction between these two general groups of elements. Most elements are metals.

Answer:

im maybe 80% sure it's hydrogen gas

Answer:

B. Electrons have the most mass of the

subatomic particles

Compared to the mass of neutron and proton, mass of electron is negligible.

Answer:

B

Explanation:

when creating a Bohr model, you will usually mark protons + or P and neutrons are usually 0 or N.

Electrons are on the rings surrounding the nucleus, but everything else is inside.

Electrons are typically represented by - or E

Protons

Protons are the subatomic particle that determines the identity of an element.

Answer:

Explanation:Protons and neutrons are located in the nucleus of an atom and determine the mass of an atom. Protons have a positive electrical charge and electrons have a negative electrical charge. Atoms that have the same number of protons and electrons do not have an electrical charge.

Answer:

Explanation:

To find the time taken given the velocity and distance covered we use the formula

[tex]t = \frac{d}{v} \\ [/tex]

From the question we have

[tex]t = \frac{405}{90} \\ [/tex]

We have the final answer as

Answer:

Point a becuse it is the closest to -5*

Explanation:

Answer:

-5

Explanation:

Negative numbers get you confused.

- = Negative

5 = Number

You know 5 right?

I I I I I - 5

5 is a really less number already.

If you add a negative it will be double small.

Now lets figure out the problem:

What is the freezing point on this graph?

-5 is the smallest number

5 is bigger than -5

15 is bigger than 5 and -5

25 is bigger than all the numbers.

I know what your thinking. 25 is totally not the answer. Its the biggest number. Freezing is a very low number. What number is the lowest out of -5, 5, 15, 25. You see -5.

Therefore, -5 is freezing.

Answer:

Boiling occurs when a liquid changes to a gas below its surface as well as at the surface. The temperature at which a liquid boils is called its boiling point. The opposite of vaporization is called condensation. Sublimation occurs when the surface particles of a solid gain enough energy that they form a gas.Boiling occurs when a liquid changes to a gas below its surface as well as at the surface.

Answer: Gases have the lowest density of the three, are highly compressible, and completely fill any container in which they are placed. Gases behave this way because their intermolecular forces are relatively weak, so their molecules are constantly moving independently of the other molecules present. Solids, in contrast, are relatively dense, rigid, and incompressible because their intermolecular forces are so strong that the molecules are essentially locked in place.

Answer:

Loses

Explanation:

liquid changes into solid, heat is released. The energy released upon freezing, known as the enthalpy of fusion, is a latent heat, and is exactly the same as the energy required to melt the same amount of the solid.

Answer:

Matter either loses or absorbs energy when it changes from one state to another. For example, when matter changes from a liquid to a solid, it loses energy. The opposite happens when matter changes from a solid to a liquid. For a solid to change to a liquid, matter must absorb energy from its surroundings.

Answer:

heat I think.....

During a change in state, energy is transferred in the form of heat.

Hence, Option (A) is correct.

When energy is added or removed to matter in the form of heat, it changes state to form a state of matter.

A state of matter is defined as one of the ways in which matter can interact with itself to form a homogeneous phase.

Therefore , During a change in state, energy is transferred in the form

of heat. Hence, Option (A) is correct.

Answer:

They're too small

Explanation:

Atoms are smaller than the wavelength of visible light

Answer:

too small

Explanation:

Answer:

The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

Explanation:

Your answer should be- that in a chemical reaction mass is neither created nor destroyed.

Explanation:

Is that good?

Step 1: add electrons to fill the 1s subshell (maximum of 2 electrons), when this is full, go to step 2. Step 2: add electrons to fill the 2s subshell (maximum of 2 electrons), when this is full, go to step 3. Step 3: add electrons to fill the 2p subshell (maximum of 6 electrons), when this is full, go to step 4. Step 4: add electrons to fill the 3s subshell (maximum of 2 electrons), when this is full, go to step 5. Step 5: add electrons to fill the 3p subshell (maximum of 6 electrons), when this is full, go to step 6. Step 6: add electrons to the 4s subshell (maximum of 2 electrons), when this is full, go to step 7. Step 7: add electrons to the 3d subshell (maximum of 10 electrons), when this is full, go to step 8. Step 8: add electrons to the 4p subshell (maximum of 6 electrons), when this is full, go to step 9. etc

beause of gravitys pull and because the atmosphere of the beyond lol also bcs this i hope this helps your welcome boo >3

Explanation:

Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.
