What is a functional group?A functional group is a specific group of atoms or bonds within a molecule that is responsible for the characteristic chemical reactions and properties of that molecule. Functional groups are the parts of organic molecules that determine their reactivity and the types of chemical reactions they can undergo.
In organic chemistry, functional groups play a crucial role in understanding the structure and behavior of molecules. Different functional groups confer distinct properties to molecules, influencing their physical properties, solubility, acidity or basicity, and interactions with other molecules.

A 2.50-mL aliquot of a solution that contains 6.4 ppm iron(III) is treated with an appropriate excess of KSCN to form the Fe(SCN)21 complex and diluted to 50.0 mL. What is the absorbance of the resulting solution at 580 nm in a 2.50-cm cell
Answer:
In the final solution, the concentration of sucrose is 0.126 M
Explanation:
The number of moles of solute in the volume taken from the more concentrated solution will be equal to the number of moles of solute in the diluted solution. Then, the concentration of the first solution can be calculated using the following equation:
Ci · Vi = Cf · Vf
Where:
Ci = concentration of the original solution
Vi = volume of the solution taken to prepare the more diluted solution.
Cf = concentration of the more diluted solution.
Vf = volume of the more diluted solution.
For the first dillution:
26.6 ml · 2.50 M = 50.0 ml · Cf
Cf = 26.6 ml · 2.50 M / 50.0 ml
Cf = 1.33 M
For the second dilution:
16.0 ml · 1.33 M = 45.0 ml · Cf
Cf = 16.0 ml · 1.33 M / 45.0 ml
Cf = 0.473 M
For the third dilution:
20.0 ml · 0.473 M = 75.0 ml · Cf
Cf = 20.0 ml · 0.473 M / 75.0 ml
Cf = 0.126 M
In the final solution, the concentration of sucrose is 0.126 M

A student borrows $10,000 from a bank but ends up paying $13,000 on the
loan over the next five years. How much interest did the student pay?
The student paid an interest of $3,000 over the next five years.
HOW TO CALCULATE INTEREST:
The interest on a borrowed amount of money can be calculated by subtracting the principal from the amount paid over time. That is;
Interest = principal - amount
According to this question, a student borrows $10,000 from a bank but ends up paying $13,000. This means that the principal is $10,000 while the amount is $13,000. The interest is calculated thus;
Interest = $13,000 - $10,000
Interest = $3,000
Therefore, the student paid an interest of $3,000 over the next five years.

Which of the following is used for purification of water?
a) Sodium bicarbonate
b) Alum
c) Copper sulphate
d) Sodium Hydroxide
A. Sodium bicarbonate is a water treatment method used to soften water (removing calcium and magnesium impurities from it) in older water softener systems. The process uses a chemical reaction to convert the calcium hydroxide (or magnesium hydroxide) into calcium carbonate, which isn't water soluble.
B. Alum, also known as potassium aluminum sulfate, can be used to purify water. ... Add 1.4 ounces of alum powder to the contaminated water in the reaction vessel and carefully stir the mixture with the stirring stick for at least five minutes. Sediment will form as the phosphorous in the water binds with the alum powder.
C. If Copper sulphate crystals are added to water it is called 'hydrated copper sulphate solution'.
If it is added to cold water then:-
it is more saturated
but if it is added to warm water then:-
it is unsaturated
and it turns bluish in colour in dissolving in water
D. Sodium hydroxide is used in the treatment of drinking water to raise the pH of the water to a level that minimizes the corrosion. Raising the pH remains one of the most effective methods for reducing lead corrosion and minimizing lead levels in drinking water.

What law of motion corresponds with this statement?
"A rifle kicks."
first law
third law
second law
Answer:
3rd lawl
Explanation:
a rifle kick is when you fire a projectile and you feel a force pushing against your hand. Rifles normally have heavier projectiles so there is more force pushing back against you. example, if you were sitting on a spinny chair with wheeles and your friend is sitting on another, and you push each other while on the chair, you will both go backward, but the lighter person will go back more. for every action, there is an equal and opposite reaction
that is the third law, also said as: "When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body."

Scientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. The term law has diverse usage in many cases across all fields of natural science.
Explanation:
I hope this helps
Answer:
Scientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. Scientific law differs from scientific theory. The main difference between a law and a theory is that a theory tries to explain the reasoning behind something that occurs in nature, whereas scientific laws are just descriptive accounts of how something occurs in nature.
A chemist performs the following reaction:
PCl5 (aq) + 4H2O (l) ⟶ H3PO4 (aq) + 5HCl (aq)
If she has 26.4 g of PCl5, what mass of water should she react to use up all of the
PCl5?
Looking for an in-depth step by step, please
Answer:
9.17 g
Explanation:
1) Calculate mols of PCl5
PCl5 (aq) + 4H2O (l) ⟶ H3PO4 (aq) + 5HCl (aq)
Mass of PCl5: 26.5g
Molar Mass of PCl5 208.24g/mol
Mol of PCl5 = Mass PCl5 /Molar mass PCl5 = 26.5g / (208.24g/mol) = 0.127257011 mol
2) Calculate mols of water needed to react
Mols of H2O per 1 Mols of PCl5 = 4 (because 4 water is needed to Phosphorus pentachloride).
Mols of H2O = Mol of PCl5 * 4 = 0.127257011 * 4 = 0.509028044 mols
3) Calculate Grams of water needed to react
Mols of H2O = 0.509028044 mols
Molar Mass of H2O = 18.015 g/mol
Mass of H2O = Mols of H2O * Molar Mass of H2O
= 0.509028044 mols* 18.015 g/mol = 9.17014021 g
sf = 3

Which one item of the list below does not describe part of beta decay?
A. The nucleus of the atom is unstable.
B. A neutron turns into a proton.
C. A proton turns into an electron.
D. An electron is ejected from the nucleus.
Answer:
C
Explanation:
When Beta decay happens, the atomic number of an element goes up, and that means there is an extra proton. A is not the answer because unstable atoms cause decay. B is also not correct because this is what happens in Beta decay: a neutron becomes a proton. D is not correct because an electron is actually emitted from the nucleus.

11) What volume will 0.75 mol of Oxygen gas (O2) occupy at 298 K and a pressure of 52.7 kPa?
Answer:
Volume = 35.3L
Explanation:
Use Ideal Gas Law (PV=nRT) and isolate for V (volume) by dividing both sides by P (pressure). You will then get the eqaution listed below and you can solve by using the method I used below.
V = nRT/P
V = (0.75kPa)(8.314)(298K)/(52.7kPa)
V = 1858.179/52.7
V = 35.3L

Consider Zn + 2HCl → ZnCl2 + H2 (g). If 0.30 mol Zn reacts with HCl, how many grams of HCl are needed?
Answer:
22 grams
Explanation:
Zn + 2HCl → ZnCl2 + H2
The first step to answering this question is to calculate the amount of moles of HCl needed. We do this by multiplying the coefficient of HCl in the equation over the coefficient of Zn.
0.30mol × [tex]\frac{2}{1}[/tex] = 0.60 mol HCl
Now, to figure out how many grams we must multiply the amount of moles of HCl by it's molar mass. This molar mass can be found by adding the molar masses of all the elements in HCl.
0.60mol × 36.46 g/mol = 21.87g
Using proper sig figs, 22 grams of HCl are required for this reaction.
