What is a photon???????????
A photon is a fundamental particle of light that carries energy and behaves both as a particle and a wave.
It carries electromagnetic waves like visible light, radio waves, X-rays, and gamma rays. Photons have energy, momentum, and angular momentum but no mass.
Photons are particles and waves in quantum physics. They absorb, emit, and scatter stuff at the speed of light in a vacuum. Photons excite electrons in atoms and molecules, starting physical and chemical reactions.
E = hf, where E is the photon's energy, h is Planck's constant, and f is its frequency. Quantum physics relies on photons to comprehend light and matter interactions.

The term "alchemy" refers to early pseudoscientific attempts to transform common
elements into more valuable elements (such as lead into gold), For one kind of atom to
become another kind of atom, which particle(s) of the atom need to be expelled or gained?
Proton
Electron
Neutron
Quantum Particles
Answer: The correct answer is option B. electron.
Explanation:
There are 3 subatomic particles:
Electrons: They carry negative charge and are present in orbits around the nucleus of an atom.Protons: They carry positive charge and are present inside the nucleus of an atomNeutrons: They does not carry any charge and are present inside the nucleus of an atom.An atom forms an ion, when it looses or gains an electron.
When an atom looses electron, it form a positive ion known as cation.When an atom gains electron, it form a negative ion known as anion.Hence, the correct answer is option B. electron.
The particle(s) of the atom that is needed to be expelled or gained in an alchemy process which involves transformation of one element into valuable elements or atom to another is B:Electron.
Alchemy can be regarded as branch of philosophical and protoscientific tradition that is traceable to China, and Europe. In the process of transformation of one element to another useful element or compounds , there is usually transfer of electron.Electronegative element like chlorine usually gain electron and are anion, while electropositive elements like potassium will loose electron( cation) all involves the transfer of electron.
Therefore, option B is correct.

In your own words, describe how magma changes form through the rock cycle to eventually become magma again.
Answer:
Magma becomes rock after the heating process has settled.
Explanation:
Magma is a kind of lava or in other words "Hot melted rock". When rock get really hot it transforms from rock it's solidified state and becomes magma. When magma is hot it can stay that way for a while or until it cools down. When magma does cool down it starts the solidifying state start to come out. If you let the magma cool it will become rock again. This process will happen over and over and it never stops. Every time magma gets cool it hardens, every time it gets hot it melts or and becomes magma. So in conclusion magma only turns back when it has been heated up and liquify.
The rock cycle explains the formation and breaking of the three forms of the rocks through various modes. The magma becomes rocks and magma again through the heating and cooling process.
What is magma?Magma has been the semi-hot liquid that is present in the mantle in the lithosphere of the earth. They have very high temperatures and can push through the crust in the form of volcanic eruptions.
The magma changes its form from semi-liquid to rocks and back to magma again through the rock cycle. The hot molten magma pushes through the crust, cools, and then forms rocks. These rocks after many years start melting at higher temperature or get deep down the mantle where it converts to semi-liquid again.
Therefore, the rock cycle converts the magma.

Marissa uses her bicycle to do a morning paper route. Starting at her home, she travels 3 km North, then 1 km East, then 3 km North, and lastly 1 km West. She completes the root in 1.5 hours. a. What is your displacement in regards to her home?
b. What is her velocity?
a. displacement = 6 km
b. velocity = 4 km/h
Further explanationGiven
a morning paper route
Required
displacement
velocity
Solution
Displacement is a vector quantity that shows changes in the position of objects in a certain interval of time. Displacement has magnitude and direction
Can be simplified displacement = distanced traveled from starting point to ending point
a. Since we only consider the starting point and the end point, we just need to add up the distances to the north
3 km + 3 km = 6 km
b. Velocity = displacement changes with time
[tex]\tt v=\dfrac{d}{t}=\dfrac{6~km}{1.5}=4~km/h[/tex]

Metals tend to — electrons and nonmetals tend to —
Electrons
Answer:
Non-metals tend to gain electrons to attain Noble Gas configurations. The have relatively high Electron affinities and high Ionization energies. Metals tend to lose electrons and non-metals tend to gain electrons, so in reactions involving these two groups, there is electron transfer from the metal to the non-metal.

48g of magnesium reacts with four moles of sulfuric acid. determine which reactant is the limiting reactant
Answer:
Magnesium is limiting reactant.
Explanation:
Based on the reaction:
Mg + H₂SO₄ → MgSO₄ + H₂
1 mole of Mg reacts per mole of sulfuric acid
To find limiting reactant we need to convert mass of magnesium to moles. If moles of Mg > moles sulfuric acid, sulfuric acid is limiting reactant and vice versa.
Moles Mg -Molar mass: 24g/mol-:
48g Mg * (1mol / 24g) = 2moles
As there are just 2 moles of Magnesium, just 2 moles of H₂SO₄ will react and 3 moles will remain. That means:
Magnesium is limiting reactant.Which of the following elements has the strongest attraction for the electrons in a bond?
