Answer:
D
Explanation:
Every enzyme has a specific substrate to bind with.
E.g.
Protien is broken down by protease enzyme
Answer:
0.4590
Explanation:
How the refractive index of the hexane + toluene mixture varies linearly with mole fraction, it means that the mole fraction is the fraction that each pure index contribute for the mixture index, so, calling <em>xh</em> the mole fraction of hexane and <em>xt</em> the mole fraction of toluene:
1.375xh + 1.497xt = 1.441
And, xh + xt = 1 (because there are only hexane and toluene in the mixture), so xt = 1- xh
1.375xh + 1.497(1-xh) = 1.441
1.375xh + 1.497 - 1.497xh = 1.441
-0.122xh = -0.056
xh = -0.056/(-0.122)
xh = 0.4590
Answer:
A solution is a heterogeneous mixture
Explanation:
This statement that a solution is a heterogeneous mixture is completely and totally wrong.
A solution is a homogeneous mixture.
Homogeneous mixtures have their constituents existing in just one phase.
- It is a homogeneous mixture of solutes and solvents.
- In a solution, the solutes particles are distributed uniformly in the solvent.
- The solute is the substance that is dissolved to make the solution.
- Solutes are usually present in a small amount than the solvent.
- The solvent acts as the dispersing medium which allows the solute to go into the solution.
- The solute can be solid, liquid or gas.
