Answer:
Beta oxidation of the odd chain heptanoic acid will produce propionyl CoA, which can be converted in several steps to oxaloacetate. Oxaloacetate is the starting material for the process of gluconeogenesis (producing glucose from noncarbohydrate precursors). This gives extra glucose to the first group, so they will be healthier and gain weight. Beta oxidation of the even chain will entirely be oxidized to acetyl Co-A (one of the precursors of the TCA cycle). This will lead to a large excess of ketone bodies instead of glucose for energy, which will lead to the second group being weak and losing weight.
Explanation:
The difference is seen in having an odd chain and an even chain of fatty acids and how they are broken down and used in the body.

Calculate the concentration of hydrochloric acid if 50.0 mL of hydrochloric acid is neutralized by 25.0 mL of 2.0 M sodium hydroxide. The neutralization reaction is shown below HCl + NaOH > H2O + NaCl
Answer:
1.0M HCl is the concentration of the acid
Explanation:
Based on the reaction, 1 mole of NaOH reacts per mole of HCl. That means the moles added of NaOH in the neutralization = Moles of HCl in the solution. With the moles and the volume in Liters we can find the molar concentration of HCl
Moles NaOH = Moles HCl:
25.0mL = 0.025L * (2.0moles / L) = 0.050moles HCl
Molarity:
0.050moles HCl / 0.0500L =

4.What is the right most significant figure in the answer?
Answer:
See explanation
Explanation:
1 mole of a gas occupies 22.4 L
x moles occupies 16.8 L
x = 1 mole * 16.8 L/22.4 L
x = 0.75 moles
number of moles = mass/molar mass
mass = number of moles * molar mass
mass = 0.75 moles * 30.01 g/mol = 22.5075 g = 2.25 * 10^1 g

What theoretical yield of NaCl would result from reacting 3.00 moles of Na2CO3 with excess HCl (aqueous)?
Answer:
350.7 g of NaCl
Explanation:
For this reactions our reactants are:
HCl and Na₂CO₃.
Then, the reaction is:
2HCl + Na₂CO₃ → 2NaCl + H₂CO₃
2 moles of hydrochloric acid react to 1 mol of sodium carbonate in order to produce 2 moles of salt and 1 mol of carbonic acid.
Ratio is 1:2. 1 mol of sodium carbonate can produce 2 moles of NaCl
Then, 3 moles of carbonate may produce (3 . 2) /1 = 6
We convert the moles to mass to determine the theoretical yield
6 mol . 58.45g /mol = 350.7 g
The theoretical yield of NaCl produced is 350.7 g.
What is NaCl?NaCl is a salt, and it is an ionic compound.
The reaction is
[tex]\rm 2HCl + Na_2CO_3 \rightarrow 2NaCl + H_2CO_3[/tex]
2 mol of HCl reacts with 1 mol of [tex]Na_2CO_3[/tex] and produces 2 mol of NaCl and 1 mol of [tex]H_2CO_3[/tex].
The ratio will be [tex]Na_2CO_3[/tex] : NaCl
1 : 2
Then, for 3 mol of [tex]Na_2CO_3[/tex]
[tex]\dfrac{3 \times 2}{1} = 6[/tex]
Now, convert the moles to mass
[tex]6\; mol \times 58.45g /mol = 350.7 g[/tex]
Thus, the theoretical yield produced is 350.7 g.

Explanation:
You had a closed tank of air at a pressure of 4 atm and temperature of 20 degrees Celsius. When the tank and the air are heated to 40 degrees Celsius, what is the pressure if the volume remains constant?
Answer:
The pressure will be 4.27 atm.
Explanation:
Gay-Lussac's law can be expressed mathematically as follows:
[tex]\frac{P}{T} =k[/tex]
Where P = pressure, T = temperature, K = Constant
This law indicates that the quotient between pressure and temperature is constant.
This law indicates that, as long as the volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then the number of collisions with the walls increases, that is, the pressure increases. That is, the pressure of the gas is directly proportional to its temperature.
In short, when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases.
You want to study two different states, an initial state and a final state. You have a gas that is at a pressure P1 and a temperature T1 at the beginning of the experiment. By varying the temperature to a new value T2, then the pressure will change to P2, and the following will be fulfilled:
[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]
In this case:
P1= 4 atmT1= 20 C= 293 K (being 0 C= 273 K)P2= ?T2= 40 C= 313 KReplacing:
[tex]\frac{4 atm}{293 K} =\frac{P2}{313 K}[/tex]
Solving:
[tex]P2= 313 K* \frac{4 atm}{293 K}[/tex]
P2= 4.27 atm
The pressure will be 4.27 atm.

Answer:
2Mg(s) +O₂(g) → 2MgO(s)
Explanation:
Mg(s) +O₂(g) → MgO(s)
When a chemical equation is balanced, the number of atoms of each element is equal on both sides of the arrow. We usually balance O and H last.
In this case, the number of Mg atoms is equal on both sides. Thus, let's move on to balance the O atoms. On the left side, there are 2 O atoms, while there is only 1 O atom on the left side. Thus, write a '2' in front of MgO.
Mg(s) +O₂(g) → 2MgO(s)
Now, the number of Mg atoms is not equal. Write a '2' in front of Mg to balance it.
2Mg(s) +O₂(g) → 2MgO(s)
The equation is now balanced with 2 Mg atoms and 2 O atoms on each side.
Fluorine gas a 300 K occupies a volume of 500 mL. To what temperature should it be lowered to bring the volume to 300 mL?
The temperature should be lowered to 300K to bring the volume to 300mL.
What is temperature?Temperature is the degree of hotness or coldness of a place or a body. The SI unit of temperature is Kelvin.
What is volume?Volume is the amount of space occupied by matter. The SI unit of volume is cubic metre.
Using Charles law,
V1/V2 = T1/T2
Where, V1 and T1 are the initial volume and temperature
Similarly, V₂ and T₂ are the final volume and temperature.
Given:
V1 = 500mL
T1 = 300K
V2 = 300mL
T2 = ?
V1T2/V1 = V2T1/V1
T2 = V2T1/V1
= 300mL x 300K/500mL
T2 = 180K
Hence, the temperature should be lowered to 300K to bring the volume to 300mL.

How many atoms are there in 8.80 moles magnesium chloride? (write your answer in scientific notation).
Answer:
There are 5.30*10²⁴ atoms in 8.80 moles magnesium chloride.
Explanation:
Avogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension. Avogadro's number applies to any substance.
Then you can apply the following rule of three: if 1 mole of magnesium chloride contains 6.023*10²³ atoms, 8.80 moles of magnesium chloride contain how many moles of atoms?
[tex]amount of atoms=\frac{8.80 moles* 6.023*10^{23} atoms }{1 mole}[/tex]

You are given three liquids. You know that one of them is a suspension, one is a solution with nonelectrolytes, and the other is a solution with electrolytes. Describe the process by which you would differentiate between the three.
Answer:
decant/ filter then decompose the electrolytes by electrolysis
Explanation:
Differentiation of suspension solution is done by filtering and differentiation of electrolyte and non-electrolyte solution is done by electrolysis process.
What is electrolysis process?Electrolysis process is used to decompose the any electrolyte present in any solution into their constitute ions towards the cathodes and anodes under the electric flow of current.
Process which is required to differentiate suspension solution is filtering, because in this solution suspended insoluble particles are present which get filtered. Now to differentiate between non electrolyte and electrolyte solution we will use the electrolysis process, as non electrolyte solution do not show any behavior in this.
Hence, we use filtering and electrolysis process for the differentiation.

What is genetic engineering ?Genetic engineering, often known as genetic alteration, is a technique that modifies an organism's DNA using technology developed in labs. This could entail altering a single base pair (A-T or C-G), erasing a section of DNA, or incorporating a new DNA sequence.
In order to fix genetic flaws and hence prevent or treat hereditary illnesses, gene therapy aims to change specific genes.
The goal of genetic engineering is to alter the genes to increase the organism's capabilities beyond what is typical.
The term "genetic engineering" originally applied to a number of methods for modifying or altering living things through their heredity and reproductive processes.
