A species acts as an oxidizing agent if it gains electrons in a half-reaction. Conversely, it could potentially act as a reducing agent if it loses electrons in a half-reaction.
REDOX REACTION:
Redox (oxidation-reduction) reaction is a type of reaction that involves the loss and gain of electrons by substances involved. Redox reaction involves a reducing agent and an oxidizing agent. Oxidizing agent gains electrons in a redox reaction while reducing agent loses electrons. Oxidizing agent gets reduced in the process while reducing agent gets oxidized.Learn more about redox reaction at: https://brainly.com/question/13293425?referrer=searchResults
what is distillation used to seperate
Distillation is used to separate liquids from nonvolatile solids as in separation of alcoholic Liquors from fermented materials or in the separation of two or more liquids having different boiling points as in the separation of gasoline Carrison and lubricating oil from crude oil

Explanation:
Write the balanced chemical equation for the following reaction. Also, classify the
reaction as sythesis, decomposition, single replacement, double replacement, or combustion.
aluminum sulfate + barium chloride —> aluminum chloride + barium sulfate
Answer:
Reaction: Al2(SO4)3 + 3BaCl2 --> 2AlCl3 + 3BaSO4
Type: Double Replacement
Explanation:
1.) First you need to understand what the different reactions are
a.) Synthesis: is a reaction where two or more substances will combine with each other to make one product.
Ex: A + B → AB
b.) Decomposition: when one compound breaks down into two or more substances. (Opposite of synthesis)
Ex: AB → A + B
c.) Single Replacement: when one element replaces another one in a reaction
Ex: A + BC → AC + B
d.) Double Replacement: when the positively charged cations and negatively charged anions of the reactants trade places. Normally this will be the two outer elements combining and the two inner ones combining.
Ex: AB + CD → AD + CB
e.) Combustion: when a substance reacts with oxygen gas and releases energy as light and heat.
Ex: CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(g)
2.) From there you can write out the formula of the different reactants and products and balance the equation.

When a glucose molecule loses a hydrogen atom in an oxidation-reduction reaction, the glucose molecule is ________
Answer:
Important
Explanation:
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.

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.

Answer:
TRUE
Explanation:The reaction is at dynamic equilibrium.
N2 + 3H2 ⇌ 2NH3
Which statement is correct?
(1 point)
The solution has the same concentrations of nitrogen gas and ammonia.
The solution has the same concentrations of nitrogen gas and ammonia.
Nitrogen and hydrogen combine at the same rate that ammonia breaks down.
Nitrogen and hydrogen combine at the same rate that ammonia breaks down.
The solution has the same concentrations of nitrogen and hydrogen gases.
The solution has the same concentrations of nitrogen and hydrogen gases.
Both directions of the reaction have stopped.
Both directions of the reaction have stopped.
Considering the definition of dynamic equilibrium, the correct answer is second option: Nitrogen and hydrogen combine at the same rate that ammonia breaks down.
Chemical equilibrium is a state of a reaction in which no changes are observed as time passes, even though the reaction continues. That is, the chemical equilibrium is established when there are two opposite reactions that take place simultaneously at the same speed.
So, dynamic equilibrium is a chemical equilibrium, which occurs when two reversible processes happen at the same speed in both directions. In this way, the concentrations of the reactants and products remain constant over time.
In summary, the correct answer is second option: Nitrogen and hydrogen combine at the same rate that ammonia breaks down.

658 mL of 0.250 M HCl solution is mixed with 325 mL of 0.600 M HCl solution. What is the molarity of the resulting solution
The molarity of the resulting solution obtained by mixing 658 mL of 0.250 M HCl solution with 325 mL of 0.600 M HCl solution is 0.366 M
We'll begin by calculating the number of mole of HCl in each solution. This can be obtained as follow:
For solution 1:Volume = 658 mL = 658 / 1000 = 0.658 L
Molarity = 0.250 M
Mole of HCl =?Mole = Molarity x Volume
Mole of HCl = 0.250 × 0.658
Mole of HCl = 0.1645 moleFor solution 2:Volume = 325 mL = 325 / 1000 = 0.325 L
Molarity = 0.6 M
Mole of HCl =?Mole = Molarity x Volume
Mole of HCl = 0.6 × 0.325
Mole of HCl = 0.195 moleNext, we shall determine the total mole of HCl in the final solution. This can be obtained as follow:Mole of HCl in solution 1 = 0.1645 mole
Mole of HCl in solution 2 = 0.195 mole
Total mole = 0.1645 + 0.195
Total mole = 0.3595 moleNext, we shall determine the total volume of the final solution.Volume of solution 1 = 0.658 L
Volume of solution 2 = 0.325 L
Total Volume = 0.658 + 0.325
Total Volume = 0.983 LFinally, we shall determine the molarity of the resulting solution.Total mole = 0.3595 mole
Total Volume = 0.983 L
Molarity =?Molarity = mole / Volume
Molarity = 0.3595 / 0.983
Molarity = 0.366 MTherefore, the molarity of the resulting solution is 0.366 M
