How is Ethyl Butyrate and Isovaleric Acid DIfferent?
Ethyl butyrate have one oxygen is an Aldehyde and isovaleric Acid have two oxygen is an carboxylic acid
Ethyl Butyrate is an ester with a molecular formula of C₆H₁₂O₂ and Isovaleric Acid is a carboxylic acid with a molecular formula of C₅H₁₀O₂.
What is an ester?In chemistry, an ester can be described as a compound derived from an oxoacid in which at least one hydroxyl group (-OH) is replaced by an alkoxy group (-O-R), as in the substitution chemical reaction of a carboxylic acid and an alcohol. But the carboxylic acid contains a carboxyl group (C(=O)OH) attached to an R-group.
Glycerides can be defined as fatty acid esters of glycerol and are one of the main classes of lipids and comprise the bulk of vegetable oils and animal fats.
Esters can be derived from carboxylic acids and are more frequently IUPAC nomenclature used for esters, based on the name for the acid followed by the suffix "-oate".
The chemical formulas of organic esters generally take the form RCO₂R’, where R and R′ are usually the hydrocarbon parts of the carboxylic acid and the alcohol respectively.

How many neutrons are in an atom of nitrogen-14?
There are 7 neutrons in an atom of nitrogen-14.
Nitrogen-14 is primarily an isotope of nitrogen, as is well known. We can also describe it as a neutral atom. Additionally, various isotopes typically have a variable ratio of neutrons to protons.
As is common knowledge, an atom's atomic number represents the total number of protons that make up its nucleus. We are informed that nitrogen has a mass number of 14, and we are also aware that nitrogen has an atomic number of 7.
It is discovered that the atomic number and the number of protons are same. This demonstrates that the nucleus of any atom that is an isotope of nitrogen will in general have seven protons.
Additionally, the number of electrons equals the amount of protons. The number of electrons will therefore be 7, we can say. We shall now determine how many neutrons are there. As is well known, mass is equal to the sum of the protons and neutrons. As a result, there will be = 14 - 7 = 7 neutrons.
As a result, we may say that nitrogen-14 has 7 electrons, 7 protons, and 7 neutrons and that it is neither an anion nor a cation. It's an impartial atom.

Classify each amino acid according to whether its side chain is predominantly protonated or deprotonated at a pH of 7. 40. The p K a values of the Asp, His, and Lys side chains are 3. 65 , 6. 00 , and 10. 53 , respectively
His and Lys are deprotonated but Asp will be protonated.
What is amino acids?Organic substances that possess both amino and carboxylic acid functional groups are known as amino acids. Although hundreds of amino acids occur in nature, the alpha-amino acids that constitute proteins are by far the most significant. The genetic coding contains only 22 alpha amino acids. Amino acids are chemicals that make proteins when they combine. The building blocks of life are amino acids and proteins. Amino acids are left over after proteins are digested or broken down. To support the body, the human body utilizes amino acids to build proteins: Food should be broken down.
Here,
As the pH is given as 7.4 and pK of His is given as 6.00. There will occur a positive charge on His when it's pH < pK therefore, it is neutral at the given pH.
As the pK value of Lys is 10.53 that is greater than the pH of 7.40. Therefore, charge on Lys is positive.
As the pK value of Asp is 3.65 which is less than the pH value of 7.40. Hence, Asp has a negative charge.
Therefore, we can conclude that His and Lys are deprotonated but Asp will be protonated.

You start with two reactants. One reactant has a mass of 13.6 grams and the other reactant has a mass of 72.9 grams. 22 grams of gas are released during the reaction. What is the total mass of all of the products formed in this reaction?
Answer:
64.5g
Explanation:
First you add the mass of reactant 1 and reactant 2, then you simply subtract the amount of gas released from your answer, and that would be the total mass of ALL the products formed.
My work:
13.6g + 72.9 = 86.5g
86.5g - 22g = 64.5g
What room in a house is similar to the chloroplasts in a cell
Before we use our imaginations to try and think of a fitting room, let's take a look at what a chloroplast is.
A chloroplast is the organelle in plant-based cells responsible for energy production. Through photosynthesis (you've probably heard of this before!), they use sunlight to create energy for the plant to function.
Since the chloroplast is the energy-maker for the cell, we need to imagine a room in a house that does something like this. There's a couple things that come to my mind. Firstly, although they don't really count as rooms, something like solar panels would probably make the most sense here. Since the answer asks for a room, though, solar panels don't work.
Maybe a kitchen? The kitchen is the room where food is created, supplying energy to all the inhabitants of a house.
I hope this helped! Learning about the components of cells is a little complicated at the start, but it's definitely a very exciting topic that only gets more and more interesting the deeper you delve into it.

Estimate the net charge at pH=7. Assume the pKa values given in the table above. Term____
The net charge at pH=7. The pKa values given in the table above will term is referred as neutral.
At pH = 7, the solution is considered neutral, which means that the concentration of H+ ions is equal to the concentration of OH- ions, i.e [H+] = [OH-] = 10^-7 M.
To estimate the net charge at pH = 7, you would need to know the pKa values of the acid and the species present in the solution. It is important to note that the net charge at pH 7 will depend on the acid and species present in the solution, and the pKa values given for that specific acid. In a neutral solution, the pH is equal to 7, which means that the concentration of H+ ions is equal to the concentration of OH- ions. Since the pH is neutral, this means that the solution has no net charge. Neutral solutions contain equal concentrations of positive and negative ions, thus the net charge is zero.

Explanation:
This is ur answer......
The Law of Conservation of MassMatter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.
The Law of Conservation of Matter also states that the matter cannot be created or destroyed. In a physical change, substances can change form, but the total mass remains the same. In a chemical change, the total mass of the reactants always equals the total mass of the products.

Which best describes the velocity of a person on a merry-go-round? * 1 point zero constant increasing continuously changing
Answer:
continuously changing
Explanation:
The velocity of a person on a merry-go-round can best be described as continuously changing. This is because the initial velocity before the ride starts would be 0. Once the ride begins, it keeps going faster and faster until it reaches a certain speed. During this time the velocity is increasing. Then it remains constant for a certain period of time and when the ride is over the velocity and speed begins to decrease until ultimately reaching a speed of 0. Therefore, it is continuously changing throughout the duration of the ride.

NO2(OH) dissolved in water is an example of an acidic salt.
Acidic salts are formed when a strong acid and a weak base react together. They are acidic in solution because they dissociate to form H+ ions and an anion. In this case, the acidic salt is NO2(OH), which when dissolved in water, dissociates to form H+ ions and OH- ions, resulting in an acidic solution.
Ni(OH)2 dissolved only in an acidic solution is an example of a basic salt.
Basic salts are formed when a strong base and a weak acid react together. They are basic in solution because they dissociate to form hydroxide ions (OH-). In this case, the basic salt is Ni(OH)2, which when dissolved only in an acidic solution will dissociate to form Ni2+ ions and OH- ions resulting in a basic solution.
