Enzymes make reactions MUCH easier and/or faster by

Chemistry
1 answer:
zimovet [89]3 years ago
3 0

Answer:

A is correct...B and C wrong I believe

Explanation:

So basically the reason A should be correct is because all enzymes do is provide alternative mechanisms for reaction to proceed and in that alternative mechanism the activation energy is lowered allowing the reactions to progress at greater speeds.

So A makes sense because The aerodynamic shape of a car, like an enzyme, does not supply energy to the car, but it can make it easier for the car to move (basically like an enzyme the car's shape is allowing the car to move faster... enzymes are not consumed in a reaction; they simply help it to occur.)

B is not correct because enzymes do not provide energy for reaction to occur. All they provide is an alternate mechanism where the activation energy is lowered so the reactions can occur at greater rate.

C is not correct because some reactions can occur without enzymes its just that they will occur at a much slower speed.

Hope this helps! I think this should be correct plz double check with your friends.

What are alluvial diamond fields?
hammer [34]

Answer:

Alluvial diamond mining occurs in riverbeds and beaches, where thousands of years of erosion and natural forces such as wind, rain, and water currents wash diamonds from their primary deposits in kimberlite pipes to beaches and riverbeds. Some alluvial deposits are from long-ago rivers.

I will give brainliest to first person who answers ,, Need help with 4&5
aleksandrvk [35]

Answer:

4. Hydrogen atoms only need two electrons in their outer level to reach the noble gas structure of helium. Once again, the covalent bond holds the two atoms together because the pair of electrons is attracted to both nuclei. The hydrogen has a helium structure, and the chlorine an argon structure.

1.0g of a protein is dissolved in 100 ml of distilled water. The resulting solution has an osmotic pressure of .001 atm. What is
Svetlanka [38]

The osmotic pressure π, is related to concentration i.e. molarity (M) through the following equation:

π = MRT ------(1)

where R = gas constant = 0.0821 L atm/mol-K

T = temperature (let us assume 25 C = 25 + 273 = 298 K)

M = π/RT = 0.001/0.0821 * 298 = 4.09 * 10^-5 M

Now,

molarity = moles of solute/volume of solvent in Liters

            = (mass of protein/molar mass)/volume

4.09 * 10^-5 moles/L = (1.0 g/molar mass)/0.1 L

Molar mass of protein = 2.445 * 10^5 g/mole

Calculate the percentage of CL in AL(CLO3)3​
Anna35 [415]

Answer:

38.4%

Explanation:

We'll begin by calculating the molar mass of Al(ClO₃)₃. This can be obtained as follow:

Molar mass of Al(ClO₃)₃

= 27 + 3[35.5 + (16×3)]

= 27 + 3[35.5 + 48]

= 27 + 3[83.5]

= 27 + 250.5

= 277.5 g/mol

Next, we shall determine the mass of Cl in Al(ClO₃)₃. This can be obtained as follow:

Mass of Cl in Al(ClO₃)₃ = 3 × Cl

= 3 × 35.5

= 106.5 g

Finally, we shall determine the percentage of Cl in Al(ClO₃)₃. This can be obtained as follow:

Mass of Cl in Al(ClO₃)₃ = 106.5 g

Mass of Al(ClO₃)₃ = 277.5 g

Percentage of Cl =?

Percentage of Cl = mass of Cl / mass of Al(ClO₃)₃ × 100

Percentage of Cl = 106.5 / 277.5 × 100

Percentage of Cl = 38.4%
