This is a redox reaction but not a combustion reaction.
Redox Reaction
A type of chemical reaction that involves a transfer of electrons or gain of electrons between two-element. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes.
Combustion reaction
It must have two products. CO2 and H2Ooxygen in the reactant is must.
∴ The reaction is Redox ✓ not combustion

What are electrons?An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom) or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels. The charge on a single electron is considered the unit electrical charge.
Electrons are sub-atomic particles that occupy energy levels in an atom of any chemical element. These electrons may move from one energy level to another.
Electrons may move from a lower energy level or ground state to an excited state or high energy level, or else move from a higher energy level to a lower energy level.
When an electron moves from a lower energy level to a higher energy level energy is absorbed by the atom, and when the movement is from a higher energy level to lower energy is released mainly as light.
Hence, option A is correct.

what do you do if you add a bit too much solvent when filling the volumetric flask to the mark
If excess solvent is added, discard the entire solution and begin the process of preparing the solution afresh.
It is common to prepare solutions using a standard volumetric flask. In this method, the required amount of solid or liquid is added to the volumetric flask and made up to mark with solvent.
Sometimes, it is possible to mistakenly exceed the mark as the solvent is added. In such cases, you must discard the entire solution and begin the process of preparing the solution afresh.

Explanation:
"Solution is a homogeneous mixture" explain
Answer:
solution is equal distribution of a solute and liquid
Explanation:
for example water and sugar make a solution
Solutions with a uniform composition are homogeneous solutions. A homogeneous solution, then, has an equal concentration of the constituent substances throughout the entire solution.
Similar to how water molecules are evenly distributed among the Na+ and Cl- ions when sodium chloride dissolves in it. The mixture's composition is constant throughout, and it is difficult to separate the components from one another. Solutions are homogeneous mixtures, which can contain substances in either state (solid, liquid, or gas).
Even if the components were evenly dispersed, they could still be separated at some point in a homogeneous mixture. The components may need to be separated using a procedure like evaporation, distillation, or chromatography, but this is still possible.

How do the atoms aluminum and fluorine react to form the compound aluminum fluoride?
Answer:
Aluminum fluoride is an ionic compound. Meaning that the two elements form a ionic bond. In ionic bonding, atoms receive and donate electrons in order to become stable. In this case, aluminum donates its three outer electrons to three fluorine atoms. Aluminum forms a triple positive aluminium ion (Becomes a cation) and fluorine forms three single negative fluoride ions (Becomes a anion).

Answer:
B no. is the answer because
Explanation:
acids increase the hydrogen ion concentration, which provides more ionsan acid comes in contact with a metal, the acid steals free electrons away. That loosens the bonds holding metal atoms in place, so the metal dissolves. That's a chemical change, so the ability of acids to dissolve metals is a chemical propertyWhen a strong acid is neutralized by a strong base there are no excess hydrogen ions left in the solution. The solution is said to be neutral as it is neither acidic nor alkaline. The pH of such a solution is close to a value of 7; the exact pH value is dependent on the temperature of the solution.So this can probably be the the answer
