What are Catalyst? What is the definition of Catalyst
Answer:
a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change
a catalyst is a substance that increases the speed of reaction by lowering the activation energy or providing an alternative pathway of a lower activation energy(more likely for enzymes in bio).
it also doesnt take part in the reaction but in chemistry, there are homologous and homogenous catalysts where some may take part in the rxn BUT they are regenerated and are not used up
chem: more particles will have the energy to overcome the activation energy, resulting in a higher frequency of effective collision, so the rate of rxn ↑. (usually catalyst is transition metal)
bio: enzyme-substrate complex, where it is essentially what happens in the chemistry part above but the conclusion is that it takes lesser time for nutrients to be broken down and therefore digested.
What are the two most common unwanted side reactions which can occur when monosaccharides are treated with base?
Epimerization and Enediol rearrangement are the two most common unwanted side reactions which can occur when monosaccharides are treated with base.
Epimerization is a process in stereochemistry in which there is a change in the configuration of only one chiral centre. As a result, a diastereomer is formed. The classical example of this in medicine is tetracycline. In acidic conditions around pH 4, tetracycline readily undergoes epimerization at position 4, and an inactive 4-epitetracycline is produced, which on dehydration forms 4-epianhydrotetracycyline, a highly toxic product. This toxic compound can also be formed from acid catalysed (at lower pH) dehydration of tetracycline via anhydrotetracycline.
Enediol rearrangement is a transformation which occurs at basic medium and allows the conversion of epimers, defined as isomeric forms that differ in the position of the hydroxyl group at C-2. In this way it is possible to transform through the enediol intermediate glucose to mannose and vice versa.
Another important isomerization process through the enediol rearrangement is the interconversion of glucose and fructose. Thus, the enolization proceeds by migration of proton at position 2, to carbon at 1.
Monosaccharides contain both alcohol and carbonyl functional groups. This allows monosaccharides to undergo many of the reactions typical for these functional groups. In particular, alcohols can be converted to esters, converted to ethers, converted to acetals, or oxidized. Carbonyls can be reacted with nucleophiles, be reduced to form alcohols, or be oxidized to form carboxylic acids.

A full 15.0 L scuba tank at 295 K contains 144 moles of air and has a pressure of 234 atm. At the end of the dive, the tank has a pressure of 68.0 atm and a temperature of 280 K. How many moles of air are left in the tank?"
Answer:
44.1 L
Explanation:
Since volume is being held constant, we can use the following variation of the Ideal Gas Law to find the new pressure.
[tex]\frac{P_1}{T_1N_1}=\frac{P_2}{T_2N_2}[/tex]
In the equation, "P₁", "T₁", and "N₁" represent the initial pressure, temperature, and moles. "P₂", "T₂", and "N₂" represent the final pressure, temperature, and moles. Your answer should have 3 sig figs to match the sig figs of the given values.
P₁ = 234 atm P₂ = 68.0 atm
T₁ = 295 K T₂ = 280 K
N₁ = 144 moles N₂ = ? moles
[tex]\frac{P_1}{T_1N_1}=\frac{P_2}{T_2N_2}[/tex] <----- Equation
[tex]\frac{234 atm}{(295 K)(144 moles)}=\frac{68.0 atm}{(280 K)N_2}[/tex] <----- Insert values
[tex]\frac{234 atm}{42480}=\frac{68.0 atm}{(280 K)N_2}[/tex] <----- Multiply 295 and 144
[tex]0.00551=\frac{68.0 atm}{(280 K)N_2}[/tex] <----- Simplify left side
[tex]1.54=\frac{68.0 atm}{N_2}[/tex] <----- Multiply both sides by 280
[tex](1.54)N_2={68.0 atm}[/tex] <----- Multiply both sides by N₂
[tex]N_2 = 44.1L[/tex] <----- Divide both sides by 1.54
There will be approximately 49.7 moles of air in the tank at the end of the dive.
The Ideal Gas Law, which asserts the following, can be used to solve this problem:
PV = nRT
Where:
P = pressure
V = volume
n = moles of gas
R = ideal gas constant
T = temperature
Let us first use the given data to obtain the initial amount of moles of air in the tank:
[tex]P_1[/tex]= 234 atm
V = 15.0 L
[tex]T_1[/tex] = 295 K, and
R = 0.0821 L/(Kmol) atm.
Using the ideal gas law equation, we can solve for [tex]n_1[/tex]:
[tex]n_1 = (P_1 * V) / (R * T_1)[/tex]
= (234 atm * 15.0 L) / (0.0821 L·atm/(K·mol) * 295 K)
≈ 189.6 moles
Using the new pressure and temperature, we can determine the exact amount of air in the tank:
P2=68.0 atm and T2=280 K
We can determine [tex]n_2[/tex] by applying the same formula:
[tex]n_2 = (P_2 * V) / (R * T_2)[/tex]
= (68.0 atm * 15.0 L) / (0.0821 L·atm/(K·mol) * 280 K)
≈ 49.7 moles
As a result, there will be approximately 49.7 moles of air in the tank at the end of the dive.

Which atom absorbs more energy- one in which an electron moves from the the second shell to the third shell, or an atom which an electron moves from the first to the third shell?
An atom which an electron moves from the first to the third shell atom absorbs more energy.
An atoms may occupy different energy states . The energy states are discrete , that means they occur at specific values only. Therefore an atom can only move to a new energy level if it absorbs or emits an amount of energy that exactly corresponds to the difference between two energy levels.
The lowest possible energy levels that the atom can occupy is called ground state.The energy levels which is higher to the ground state is called excited state.
The more energy absorb when electron move from first to third because in this second energy level have to pass to reach at third energy level.

Steam distillation:
Live steam is used in the co-distillation technique of steam distillation to separate mixture components. It works well to extract essential oil constituents with high boiling points, such as those with boiling points of 200°C. However, the oil vapors themselves are warmer—around 100°C—helping to maintain the compounds' structural integrity. It enables distillation to be carried out at lower temperatures than the boiling points of the constituent parts. The high-boiling essential oils are vaporized by steam, and after passing through a cooling system, the hot vapors that were formed from them condense back into a liquid along with water. A two-phase distillate, consisting of a water layer and an oil layer, is created because the oils are immiscible in water.Learn more about the Steam distillation with the help of the given link:

VCO₃ -------------------> V²⁺ and CO₃²⁻
Cr₂(SO₄)₃ -------------> Cr³⁺ and SO₄²⁻
(NH₄)₂S ----------------> NH₄⁺ and S²⁻
Explanation:
Within ionic compounds, the cation is listed first, followed by the anion. Some of the ions are polyatomic, meaning they are covalently bonded to other elements. Polyatomic ions always have a specific charge.
All of these ionic compounds have an overall charge of 0. As such, the charges of the cations and anions must balance out. In order to do so, there are some compounds which have more than one atom of each ion.
2.) CrO₂
------> Oxygen (O) always forms the anion, O²⁻.
------> Therefore, if there are 2 oxygen anions, the chromium (Cr) must have the cationic form of Cr⁴⁺.
------> +4 + (-2) + (-2) = 0
3.) VCO₃
------> Carbonate (CO₃), a polyatomic ion, always has the state CO₃²⁻.
------> If there is only one atom of each ion, the charges must perfectly balance, making vanadium (V) be the cation V²⁺.
------> +2 + (-2) = 0
4.) Cr₂(SO₄)₃
------> Sulfate (SO₄), a polyatomic ion, always has the state SO₄²⁻.
-------> The only way the charges could balance out is if the chromium (Cr) is in the cationic form Cr³⁺.
------> +3 + 3 + (-2) + (-2) + (-2) = 0
5.) (NH₄)₂S
------> Ammonium (NH₄), a polyatomic ion, always has the state NH₄⁺.
------> Sulfur (S) always forms the anion S²⁻.
------> +1 + 1 + (-2) = 0

While denitrification only reduces nitrate to molecular nitrogen, anaerobic respiration employs nitrate as the bacterium's final electron acceptor, reducing it to a range of chemicals.The nitrate reduction test is based on the detection of nitrite and its capacity to produce a red precipitate (prontosil), which is a water-soluble azo dye, when it combines with sulfanilic acid to create a complex (nitrite-sulfanilic acid).Learn more about the Nitrate reduction test with the help of the given link:

Risk premiums on corporate bonds tend to ________ during business cycle expansions and ________ during recessions, everything else held constant.
Risk premiums on corporate bonds tend to decreases during business cycle expansions and increases during recessions, everything else held constant.
A bond that is sold for more than it is worth. when the prevailing interest rate is lower than the coupon rate.
Corporate bond risk premiums have become typically anticyclical, meaning they rise during recessions as well as fall throughout expansions of the business cycle.
Bonds that trade above their face value or cost more than their face value are referred to as premium bonds. Since its interest rate has been higher than those of the current market, a bond may trade at a premium. The bond's price may also increase as a result of the company's as well as the bond's credit ratings.

What does the kinetic theory state about the relationship between the speed and temperature of gas molecules?
As the temperature increases, the speed of gas molecules increases
The kinetic theory state about the relationship between the speed and temperature of gas molecules as with an increase in temperature, the speed of gas molecules increases.
The energy that an object possesses as a result of its motion is known as kinetic energy.
The average of the kinetic energies of all the particles in a system is known as the average kinetic energy.
The following equation provides the answer:
K = [tex]\frac{3RT}{2}[/tex]
K= kinetic energy
R= gas constant
T= temperature
It is clear from above that kinetic energy and system temperature are inversely correlated. Therefore, if the temperature is higher, the system's average kinetic energy will also be higher, increasing the speed of the molecules.What does kinetic theory state?
The kinetic theory of matter states that all matter is made of small particles that are in random motion and that have space between them.
