Answer:
D
Explanation:
When substrate molecules bind to the active site of the enzyme, the enzyme undergoes a slight change in shape.
uuuuuuuuuuuuuuuuuuuuuuum i think it the way its shaped
Answer:
warming up the solution.
Explanation:
- A saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent. The additional solute will not dissolve in a saturated solution.
- Supersaturated solution is a solution that contains more of the dissolved material than could be dissolved by the solvent under normal circumstances.
- A saturated solution can become supersaturated when it is cooled.
- Also, we can form a saturated solution from a supersaturated solution via warming up the solution:
<em>The solubility of solid solutes in liquid solvents increases as the solvent is warmed up.</em>
Answer:
V₂ = 123.6 L
Explanation:
According to Boyle's law pressure and volume of a gas are inversely related if amount and temperature are kept constant. For the initial and final states the gas law is given as,
P₁ V₁ = P₂ V₂ ----- (1)
Data Given;
P₁ = 103 kPa
V₁ = 30 L
P₂ = 25 kPa
V₂ = ?
Solution:
Solving equation 1 for V₂,
V₂ = P₁ V₁ / P₂
Putting values,
V₂ = (103 kPa × 30 L) ÷ 25 kPa
V₂ = 123.6 L
Result:
As the pressure is decreased from 103 kPa to 25 kPa, therefore, volume has increased from 30 L to 123.6 L.
Answer:
200cc of 5N HCl were diluted
Explanation:n
<em>Assuming the solution was diluted to prepare a 1N HCl solution:</em>
The HCl was diluted from 5N to 1N, that is a dilution of:
5N / 1N = 5 times
As the total volume of the diluted solution is 1L = 1000mL = 1000cc the amount of the concentrated solution was:
1000cc / 5 =
<h3>200cc of 5N HCl were diluted</h3>
