In the final step of the enzyme substrate complex, the product leaves the active site of the enzyme .
The whole process of enzyme substrate complex is a temporary molecule formed when an enzyme comes into perfect contact with its substrate. Without its substrate an enzyme is a slightly different shape. The substrate causes a conformational change when the substrate enters the active site. The active site is the area of the enzyme capable of forming weak bonds with the substrate. some enzyme functions independently. This shape change can force two or more substrate molecules together or split individual molecules into smaller parts. Most reactions that cells use to stay alive require the actions of enzymes to happen fast enough to be useful. It is influenced by temperature and pH.

Answer:
0.67moles
Explanation:
The balanced equation of the chemical reaction given in this question is:
N2 + 3H2 → 2NH3
According to this equation, 3 moles of hydrogen gas (H2) produces 2 moles of ammonia gas (NH3)
Therefore, 1 mole of hydrogen gas (H2) will produce;
= 1 × 2/3
= 2/3
= 0.6666
= 0.67moles of ammonia (NH3)
I’d appreciate any help
Answer:
27 g
Explanation:
From the question,
n = Mv...................... Equation 1
Where n = number of mole of Al₂SO₄, M = Molarity of Al₂SO₄, v = Volume of the solution.
Given: M = 0.12 mol/L, v = 1.5 L.
Substitute these values into equation 1
n = 0.12×1.5
n = 0.18 mol
Also,
n = Mass(m)/Molar mass (m')
n = m/m'.
m = n×m'......................... Equation 2
Given: The molar mass of Al₂SO₄ = (27×2)+32+(16×4) = 150 g/mol
Substitute into equation 2
m = 0.18×150
m = 27 g
How many moles of KClO3 are needed to produce 480 grams of O2?
Answer:
2:3
You'd need 33.3 moles of potassium chlorate, KClO3 , to produce that much oxygen. Notice that you have a 2:3. mole ratio between potassium chlorate and oxygen gas, which means that, regardless of how many moles of the former react, you'll always produce 3/2 times more moles of the latter.

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:

Calculate the molarity of a solution prepared by dissolving 6.87 grams of AgNO3 in enough water to make 2.50 liters of solution.
Answer:
The molarity of the solution is 0.016 [tex]\frac{moles}{L}[/tex]
Explanation:
Molar concentration is a measure of the concentration of a solute in a solution.
Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.
Molarity is determined by dividing the moles of the solute by the volume of the solution:
[tex]Molarity=\frac{number of moles of solute}{volume}[/tex]
Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].
Being 169.87 g / mole the molar mass of AgNO₃, then you can apply the following rule of three: if 169.87 grams are contained in 1 mole, 6.87 grams are contained in how many moles?
[tex]amount of moles=\frac{6.87 grams*1 mole}{169.87 grams}[/tex]
amount of moles= 0.04 moles
Then:
number of moles of solute: 0.04 molesvolume: 2.50 LReplacing:
[tex]Molarity=\frac{0.04 moles}{2.50 L}[/tex]
Solving:
Molarity= 0.016 [tex]\frac{moles}{L}[/tex]
The molarity of the solution is 0.016 [tex]\frac{moles}{L}[/tex]

What causes the release of energy in an exothermic reaction? Bonds breaking Bonds breaking A catalyst A catalyst Bonds being formed Bonds being formed Electrons escaping the bond
Answer:
weak bonds break and strong bonds form
Explanation:
An exothermic reaction is a chemical reaction in which heat energy is evolved during the reaction process.
Bond formation requires energy while bond breakage releases energy. More energy is needed for the formation of weak bonds as compared to strong bonds.
Hence, when weak bonds break, they release more energy than needed to make a corresponding strong bond leading to the release of the remaining energy as heat.

what are the respective coefficients needed to balance the equation below _N2(g) + _H2(g) --> _NH3(g)
In the balanced equation, the mass of reactant is exactly equal to the mass of product. The respective coefficients needed to balance the equation is N₂(g) + 3H₂(g) ⇒ NH₃(g) .
What is balanced equation ?A chemical equation that is balanced has equal amounts of each element's atoms on both sides of the equation and conserves mass.
Because mass cannot be generated or destroyed, according to the rule of conservation of mass, a chemical equation must always be in balance.
The Law of Conservation of Mass is followed by a balanced equation. This is a crucial scientific guiding principle. Finally, a balanced equation enables us to forecast the quantity of reactants and products that will be produced. Sort of crucial if you're attempting to determine how much fuel to supply a spacecraft traveling to Mars
Thus, the balanced equation is N₂(g) + 3H₂(g) ⇒ NH₃(g) .

A 1.5 L pocket of air with a temperature of 295 K rises in the atmosphere. What will be the volume of the air pocket of the t temperature decreased to 2 celsius and the pressure is not changed.
Answer:
1.4 L.
Explanation:
Applying Charles law,
V/T = V'/T'....................... Equation 1
Where V = Initial volume, V' = Final volume, T = Initial Temperature in Kelvin, T' = Final Temperature in Kelvin.
Make V' the subject of the equation
V' = (V/T)T'..................... Euqation 2
Given: V = 1.5 L, T = 295 K, T' = 2 °C = (2+273) K = 275 K
Substitute these values into equation 2
V' = (1.5/295)275
V' = 1.398
V' ≈ 1.4 L

Describe how temperature changes the average Molecular kinetic energy?
According to Kinetic Molecular Theory, an increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often. If the reaction is kept at constant pressure, they must stay farther apart, and an increase in volume will compensate for the increase in particle collision with the surface of the container.
