Answer:
In fact, the inhibitor and substrate don't affect one another's binding to the enzyme at all. However, when the inhibitor is bound, the enzyme cannot catalyze its reaction to produce a product. Thus, noncompetitive inhibition acts by reducing the number of functional enzyme molecules that can carry out a reaction.

What can you infer about magnetic domains from the fact that they are arrangements of atoms?.
Explanation:
Q. What can you infer about magnetic domains from the fact that they are arrangements of atoms? The individual domains are extremely small.
In ferromagnetic materials, smaller groups of atoms band together into areas called domains, in which all the electrons have the same magnetic orientation. That's why you can magnetize them.An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. The poles of an electromagnet can even be reversed by reversing the flow of electricity.1. Describe what the following terms mean

According to the concept of conduction, iron belongs in the area marked with an X.
What is conduction?Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules .
When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:
1) heat conduction
2) electrical conduction

What is the molarity of a solution consisting of 105 grams of calcium nitrate and 280. grams of water?
Answer:
About 2.29 M.
Explanation:
Recall that molarity is defined by moles of solute over liters of solution.
Our solute is 105 grams of calcium nitrate (Ca(NO₃)₂)).
Convert 105 grams of Ca(NO₃)₂ to moles. The molecular weight of Ca(NO₃)₂ is 164.10 g/mol:
[tex]\displaystyle 105\text{ g Ca(NO$_3$)$_2$}\cdot \frac{1\text{ mol Ca(NO$_3$)$_2$}}{164.10\text{ g Ca(NO$_3$)$_2$}} = 0.640\text{ mol Ca(NO$_3$)$_2$}}[/tex]
Convert 280. grams of water to liters. Recall that the density of water is given by 1.00 g/mL:
[tex]\displaystyle \begin{aligned} D & = \frac{m}{V} \\ \\ V & = \frac{m}{D} \\ \\ & = \frac{(280.\text{ g})}{\left(\dfrac{1.00\text{ g}}{1\text{ mL}}\right)} \\ \\ & = 280. \text{ mL}\cdot \frac{1\text{ L}}{1000\text{ mL}} = 0.280\text{ L soln.}\end{aligned}[/tex]
Hence, the molarity of the solution is:
[tex]\displaystyle \begin{aligned} \text{M} &= \frac{\text{ mols solute}}{\text{L soln.}} \\ \\ & = \frac{(0.640\text{ mol})}{(0.280\text{ L soln.})} \\ \\ & = 2.29\text{ M} \end{aligned}[/tex]
In conclusion, the solution is about 2.29 M.

How many liter are in 55.5 grams of neon?
If you want to produce 18.48 grams of NaCl what is the minimum amount of each reactant that you must start with
The minimum amount of NaOH and HCl that must be present to produce 18.48grams of NaCl is 12.6g and 11.5g respectively.
Calculation of amount of reactantsThe balanced neutralization reaction equation for the formation of NaCl is,
NaOH + HCl ---> NaCl + H2
The molar mass of NaOH = 23+16+1 = 40g/mol
The molar mass of NaCl = 23 +35.5 = 58.5g/mol
If 40g of NaOH = 58.5g of NaCl
∴ x g of NaOH = 18.48g of NaCl
Make xg the subject of formula,
x g of NaOH = 40 × 18.48/58.5
= 739.2/58.5
= 12.6g of NaOH
The molar mass of HCl = 1 +35.5 = 36.5g/mol
If 36.5g of HCl= 58.5g of NaCl
∴ x g of HCl = 18.48g of NaCl
Make xg the subject of formula,
x g of HCl = 36.5 × 18.48/58.5
= 674.52/58.5
= 11.5g of HCl

During winter in cold climates, salt is often used on roads to prevent the buildup of slippery ice. Although salt may make driving safer, it can cause the metallic parts of cars to corrode or rust relatively quickly. In a few sentences, please explain what is occurring.
Answer:
this is because the salt may be acidic and also may have oxygen substituent which can lead to rust
During cold winters, the salt present on the roads reacts with the iron and the dew water and results in the formation of the iron oxide as rust.
What is rust?The rust has been given as the iron oxide compound, that has been formed with the reaction of the water with the iron in the presence of oxygen.

Select the correct answer from the drop-down menu. a scientist digs up sample of arctic ice that is 458,000 years old. he takes it to his lab and finds that it contains 1.675 grams of krypton-81. if the half-life of krypton-81 is 229,000 years, how much krypton-81 was present when the ice first formed? use the formula n = n0 . the ice originally contained grams of krypton 81.
The original mass of krypton 81 that is present in the ice is 6.70 grams.
How do we calculate original mass?Original mass of any substance will be calculated as below for the decomposition reaction is:
N = N₀(1/2)ⁿ, where
N = remaining mass of krypton-81 = 1.675g
N₀ = original mass of krypton-81 = ?
n will be calculated as:
n = T/t, where
T = total time period = 458,000 years
t = half life time = 229,000 years
n = 458,000/229,000 = 2
Now putting all these values on the above equation, we get
N₀ = 1.675 / (1/2)²
N₀ = 6.70 g
Hence required mass is 6.70 g.

true/false
Answer and Explanation: The answer is false.
In order to make a covalent bond, the orbitals on each atom in the bond must overlap.
Answer:
true
Explanation:
Covalent bonds are formed through the overlap of half-filled valence orbitals. Because of the overlapping, it is most probable that electrons are located within the region of the bond.
In order to make a covalent bond, the orbitals on each atom in the bond must overlap. Therefore, the given statement is true.
What is covalent bond?A covalent bond is an electron exchange usually results in the production of electron pairs between atoms. These electron couples are referred to as bonding pairs as well as sharing pairs. Covalent bonding seems to be the permanent equilibrium of atoms' forces of attraction versus attraction when atoms share electrons.
Because to electron sharing, each atom in a number of molecules can achieve the corresponding amount of the valence shell, resulting inside a stable electronic configuration. In organic chemistry, covalent bonds are far more common than ionic ones. In order to make a covalent bond, the orbitals on each atom in the bond must overlap.

Answer:
Density is the measurement of how tightly a material is packed together. It is defined as the mass per unit volume. Density Formula: ρ = m/V, where ρ is the density, m is the mass of the object and V is the volume of the object.
Explanation:
Answer:
The mass per unit volume of a substance is called density of that substance.
Explanation:
So, How does it works ?
For example: Density of gold is 19300kg/cubic meter. It means that if there gold having volume of a cubic meter its mass will be 19300 kg... Density of plastics are less than that of density of metals... I.e. if we take plastic having volume 2 cubic meter & gold having volume 1 cubic meter we will find mass of gold is far more compared to that of plastic.. Thus, density refers how much tightly the molecules of a substance are bonded together.
