During the course of a catalytic reaction the following occurs: 1) Substrate is covalently bound and oriented with proximity to the active site residues. 2) Negative charge builds up on the substrate and is stabilized. 3) Oxidation of the enzyme followed by reduction to complete the catalytic cycle. What type of chemical species can facilitate these reactions? A) nucleophilic amino acids B) electrophilic groups C) prosthetic phosphate groups D) transition metal anions E) transition metal cations
During the course of a catalytic reaction Substrate is covalently bound and oriented with proximity to the active site residues.
The type of chemical species which can facilitate these reactions is transition metal cations.
What is an Enzyme?These are proteins that act as biological catalysts and accelerate chemical reactions.
They function by binding to the substrate and requires the use of transition metal cations which acts as cofactors.

How does weathering help to create soil? Please Help Asap
Weathering adds organic material to the soil.
Weathering builds up the rocks that create the deepest soil layer.
Weathering compacts small particles into larger rock pieces.
Weathering breaks parent material into smaller pieces.
Answer:
D. Weathering breaks parent material into smaller pieces.
Explanation:
I believe it is D. because weathering breaks down and loosens it into smaller pieces.
I hope it helps! Have a great day!
Muffin ^^
Answer:
Your answer would be:
D.) Weathering breaks parent material into smaller pieces.
Explanation:
Weathering breaks down and loosens the surface minerals of rock. The broken rocks are transported to another place where it decomposes and forms soil. Therefore weathering is important for soil formation. Without it, there will be likely less soil.
Have a great rest of your day

Why isn't this structure possible for an isomer of butanoic acid? Like why does the acid group always be on the end of a molecule?
It is not possible for the structure to be an isomer of butanoic acid because it consists of 5 carbon atoms.
What is an isomer of butanoic acid?An isomer of butanoic acid is a chemical compound with the same molecular formula but a different structural arrangement of its atoms.
Butanoic acid, also known as butyric acid, has the molecular formula C₄H₈O₂. It is a carboxylic acid with a straight-chain arrangement of four carbon atoms.
One isomer of butanoic acid is called isobutyric acid (2-methylpropanoic acid). Isobutyric acid has the same molecular formula C₄H₈O₂, but its carbon atoms are arranged in a branched structure.
So from the given structural formula, it is not possible for the structure to be an isomer of butanoic acid because it consists of 5 carbon atoms.

A radioactive element has a half-life of six days. What is the approximate decay rate of the element after the first day? 0. 9% 1. 5% 8. 3% 10. 9%.
A radioactive element has a half-life of six days then the approximate decay rate of the element after the first day is 8.3%.
What is the half life time?Half life time is that time during which half of the concentration of reactant will changed into the product.
According to the question:
In 6 days = 50% of the reactant will change into product
In 1 day = 50%/6 of the reactant will change into product
So, in 1 day = 8.3% of the reactant will change into product
Hence option (3) is correct.

How does an electron move from the ground state to an excited state?
Answer:
It goes through a process called absorption. This is when an atom absorbs the energy from its surroundings. The electrons move from the ground state to the excited state because of this process. Once the atoms absorb energy, that affects the inner development when shifting to a new state of being.
Explanation:
The process that is known as absorption is when an atom absorbs energy from its surrounding racing it's energy level causing it to go into an excited state or highly-reactive state. When an atom goes through this process, electrons absorb the energy and raise to higher energy levels, therefore raising the stage of itself. This is how it gets into a excited state.

Writing a Scientific Argument
Write a scientific argument that answers the question Why is the liquid oxygen machine producing less liquid oxygen than normal?
State your claim and use evidence to support it. For each piece of evidence you use, explain how the evidence supports your claim or refutes another claim. Remember to explain what happened at both the macro and molecular scales.
Answer: The liquid oxygen machine is producing less liquid oxygen than normal because there's a low attraction between the molecules.
It should be noted that oxygen in its liquid state will take up less space. It can also be stored at a lower pressure than when it's in its gaseous state.
Explanation:
From the complete question, the liquid oxygen evaporates at a slightly higher The reason for this is due to the fact that they have similarly low attraction between molecules.
True or false: water is weird. Normally the solid form of a substance is more
dense/compact than the liquid form. When water freezes it forms
crystalline structures that make the molecules spread out causing ice to be
less dense than water and float. This is true of all substances.
Answer:
this would be true friend :)
Explanation:
for density, it generally goes solids, liquids, then gas in order from most dense, to least dense.

A student used 1.2 g of hydrate in the first trial and 1.6 g in the second trial. Explain fully why her mass percent of water will be the same for both trials even though she used more hydrate in the second trial. (Do not simply state that the mass percent is an intensive property ).
Both trials of 1.2 g and 1.6 g will have the same mass percent of water because the ratio of the salt to the water of hydration is always constant for any hydrated salt.
Water of hydrationFor every hydrated salt, the ratio of the salt to the water of hydration remains constant irrespective of the amount of salt taken for experimental analysis.
For example, assuming the mass percent of water in 10g of a hydrated salt is 40%, if 100g of the same salt is taken, the mass percent will remain 40%.

CaO mass is 25 grams
CO2 volume is 144 liters
CaO + CO2 = CaCO3
what is the mass of CaCO3?
Answer:
100.09 amu is the answer.
Answer:
45g
Explanation:
first we will find out which is the limiting reactant (hope you know how to find it)
Cao is the limiting reactant
so
we will find the number of moles of cao which is 0.45 mol
as according to the equation cao and caco3 have ratios 1:1 so both will have the same no. of moles
then by multiplying 0.45mol by 100 (mr of caco3) we will get the mass of caco3 which is 45g

12. You want to create a 0. 55M Potassium Chloride solution. You mass 3. 00 grams of Potassium chloride
How much water is needed?
I suppose that you want to produce a 0.25 M solution of KCl
You do not want tp produce 0.25 mol of KCl.
Molar mass KCl = 39.1 + 35.45 = 74.55 g/mol
Mass of 0.25 mol KCl = 0.25 mol * 74.55 g/mol =18.64 g
To produce a 0.25 M solution of KCl = 18.64 g would require a solution volume of 1.0 L or 1000 mL
You have only 5.00 g ( NOT 5.00 gm) of KCl
Volume of solution required = 5 g / 18.64 g * 1000 mL = 268 mL solution
You dissolve the 5 g KCl in some water and then make up the final solution volume to 268 mL
This does NOT mean that you dissolve the 5 g KCl in 268 mL water .
