Alpha-linolenic acid (ALA) is an essential omega-3 fatty acid that is found in certain plant oils, such as flaxseed and canola oil, and in some nuts and seeds. It is considered an essential fatty acid because the body cannot produce it and it must be obtained through the diet.
Eicosapentaenoic acid (EPA) is a biologically available form of omega-3 fatty acid that can be produced from ALA through a series of metabolic processes. The percentage of ALA that converts to EPA in the body varies depending on a number of factors, such as individual genetics, dietary factors, and overall health.
On average, the conversion rate of ALA to EPA is relatively low, with estimates ranging from 0.1-9% in healthy adults. The exact percentage of conversion is not well-established, but it is believed to be low due to the limited activity of the enzymes involved in the conversion process.
It's also important to note that not all of the EPA produced from ALA will be used by the body, as some of it will be converted to other fatty acids such as docosahexaenoic acid (DHA). The conversion rate of ALA to DHA is even lower, typically less than 0.5%.
It's important to note that some studies show that supplementation with EPA and DHA may be more beneficial for some health outcomes than supplementing with ALA, as these forms of omega-3 are more easily incorporated into cell membranes and have a more direct effect on the body.

Answer:
i) Iron metal is obtained
ii) Fe2O3 + 3CO → 2Fe + 3CO2
iii) CO is the reducing agent
Explanation:
i) When carbon monoxide is passed over iron III oxide, iron metal is obtained
ii) The equation of the reaction is;
Fe2O3 + 3CO → 2Fe + 3CO2
iii) The reaction is a redox reaction. CO acts as the reducing agent while Fe2O3 acts as the oxidizing agent. We know that CO is the reducing agent because its oxidation number increased from left to right. Recall that the oxidation number of the reducing agent increases from left to right in a redox reaction
aseous ammonia chemically reacts with oxygen gas to produce nitrogen monoxide gas and water vapor. Calculate the moles of ammonia needed to produce 1.3 mole of water

[tex]4NH_{3}+5O_{2}- > 4NO +6H_{2}O[/tex]
In chemistry, stoichiometry is the measurement of the ratios in which different substances or elements interact. The laws of conservation of mass, energy, and weights or volumes serve as the foundation for the rules used to determine stoichiometric relationships.
stoichiometric moles of ammonia reacting = [tex]\frac{moles}{stoichiometry}[/tex]
stoichiometric moles of water reacting = [tex]\frac{1.3}{6} =0.21[/tex]
0.21 stoichiometric moles of water is given by 0.21 stoichiometric moles of water
so moles of ammonia will form = stoichiometric moles * stoichiometry
moles of ammonia will form = 0.21 * 4 = 0.84 mol
so moles of ammonia produced by reaction = 0.84 mol

A compound is found to contain 59.94 % carbon, 13.44 % hydrogen, and 26.62 % oxygen by mass. What is the empirical formula for this compound
The empirical formula for this compound containing 59.94 % carbon, 13.44 % hydrogen, and 26.62 % oxygen by mass is C3H8CO.
Given the % of carbon = 59.94%
The % of hydrogen = 13.44%
The % of oxygen = 26.62%
If a percentage is provided, we will assume that the entire mass is 100 grams. As a result, each element's mass is equal to the percentage indicated. Then
the mass of carbon (m1) = 59.94g
The mass of hydrogen (m2) = 13.44g
The mass of oxygen (m3) = 26.62g
We know the molar mass of C = 12 g/mole
The Molar mass of H = 1 g/mole
The Molar mass of O = 16 g/mole
The moles of carbon = 59.94/12 = 4.995
The moles of hydrogen = 13.44/1 = 13.44
The moles of oxygen = 26.62/16 = 1.664
Divide each mole value by the lowest computed mole number to get the mole ratio.
For C = 4.995/1.664 = 3 , For H = 13.44/1.664 = 8 and For O = 1.664/1.664 = 1. Then the empirical formula = C3H8CO

Are CO2 and O2 inversely related?
Yes carbon dioxide and oxygen are inversely related to each other.
Bohr effect is a result of the effect of carbon dioxide has on hemoglobin affinity for oxygen. Bohr's effect describes the hemoglobin's lower affinity for oxygen secondary to increases in the partial pressure of the carbon dioxide and decreases the pH of blood. This lower affinity, in turn, enhances the unloading of oxygen into the tissues to meet the oxygen demand of the tissue.
Thus, the relationship between CO₂ and hemoglobin affinity for oxygen can be described as an inverse relationship meaning when one goes one way, and the other goes the other way.

Order each of the sets of compounds with respect to Sy2 reactivity (1 = fastest). A. CI B. H2C=CHCH2CI C. CI
Compound A Compound B
The order of Sy2 reactivity for the sets of compounds you provided would be:
Compound B (H2C=CHCH2CI)
Compound C (CI)
Compound A (CI)
This is because Compound B has the greatest electron-donating ability due to the presence of the alkyl group attached to the carbon bearing the halogen, making it the most nucleophilic and therefore the most reactive in an Sy2 reaction. Compound C is less reactive than B because it lacks the electron-donating alkyl group, and Compound A is the least reactive due to the lack of electron-donating groups.The term "Sy2 reactivity" refers to the reactivity of a compound in a nucleophilic substitution reaction where the leaving group is displaced by a nucleophile. The abbreviation "Sy" stands for "substitution" and the subscript "2" indicates that the reaction is bimolecular, meaning that the rate of the reaction is dependent on the concentrations of both the substrate and the nucleophile.

BRAINLIEST HELP PLEASE. 6. In order to produce CO2, a student put a sample of calcium carbonate in a flask and
added hydrochloric acid using the following equation:
CaCO3 + 2HCI- H2O + CO2 + CaCl2
The student finds the mass of CO2 generated in the lab to be 100 g. If the student
began with 200 g of HCl and excess CaCO3, what was the percent yield of CO2?
On adding 200g hydrochloric acid to excess calcium carbonate, the percent yield of carbon dioxide is equal to 82.84%.
200g of HCl was added to an excess amount of calcium carbonate to produce 100g of carbon dioxide along with water and calcium chloride. The reaction is written as:
CaCO₃ + 2HCl → H₂O + CO₂ + CaCl₂
Since calcium carbonate is excess, two moles of hydrochloric acid gives rise to one mole of carbon dioxide.
To calculate the percent yield, we can use stoichiometry,
The molar mass of hydrochloric acid = 36.46 g/mol
The molar mass of carbon dioxide = 44.01 g/mol
To calculate theoretical yield,
200g HCl/1 × 1 mole HCl/36.46g HCl × 1 mol CO₂ /2mol HCl × 44.01 mol CO₂/ 1 mole CO₂
= 120.707 g
To calculate the percent yield,
The amount of CO₂ produced = 100g
Dividing 100 by the theoretical yield
= 100/120.707 = 0.8284
Now multiplying the value by 100
= 0.8284 × 100 = 82.84 %

an empty bottle has a volume of 2.0 L at room temperature 25 C. What will the new volume be if you put it in the freezer (-4C)
An empty bottle has volume of 2 L at room temperature 25°C . If we put it in the freezer (-4°C), the new volume will be 1.8L.
According to Charles' law, " the volume of a given amount of gas held at constant pressure is directly proportional to the kelvin temperature". The equation is represented as:
V₁/T₁ = V₂/T₂
This means, with increase in temperature, volume will also increase and vice versa.
According to question,
V₁ = 2.0 L
T₁ = 25°C = (25+273)K = 298 K
T₂ = -4°C = (-4 + 273)K = 269 K
Using Charles' law equation,
V₁/T₁ = V₂/T₂
⇒V₂ = V₁×T₂ / T₁
⇒V₂ = 2L × 269 K/298K
⇒V₂ = 1.8 L
Thus, the new volume when the bottle is put in a freezer (-4°C ) is 1.8 L
