Answer:
-65.897°C.
Explanation:
- Adding solute to water causes depression of the boiling point.
- The depression in freezing point (ΔTf) can be calculated using the relation: <em>ΔTf = Kf.m,</em>
where, ΔTf is the depression in freezing point of chloroform solution.
Kf is the molal depression constant of chloroform (Kf = 4.70°C.kg/mol).
m is the molality of the solution (m = 0.51 m).
∴ ΔTf = Kf.m = (4.70°C.kg/mol)(0.51 m) = 2.397°C.
∴ The freezing point of the solution = (freezing point of chloroform) - ΔTf = (-63.5°C) - (2.397°C) = -65.897°C.
Answer:
<em>Minerals are naturally occurring inorganic solids with a crystalline structure and a definite range of chemical formula. Ores are concentrations of minerals in rock that are high enough to be economically extracted for use. All ores are minerals, but all minerals are not necessarily ores.</em>

Answer:
That the enzyme is a protein
Explanation:
Remember the proteins are groups of thousands of amino acids, by their owns, since they are very small units, they can not act as a catalyst.
But as a polymer, the protein enzyme, have different shape, size and physical and chemical properties than a single monomer.
Remember also the proteins to be active, they need certain number of amino acids join together to form a specific shape that is going to match with another molecule to speed the chemical reaction and act as an enzyme.
The procedural steps in order to get iodinate salicylamide are as follows:
- It begins first at a laboratory.
- Secondly, one has to dissolve salicylamide in ethanol.
- Then one has to add sodium iodide.
- Later on, one has to add sodium hypochlorite to the ice cold solution of salicylamide and sodium iodide.
- Thereafter one has to sodium thiosulfate.
- It is better to Acidify by a person adding about 10% of HCl.
- The one has to collect the crude product through the use of vacuum filtration.
- Lastly one then Recrystallize from hot ethanol.
<h3>What is Electrophilic aromatic substitution?</h3>
The Electrophilic aromatic substitution is known to be a kind of an organic reaction where an atom is said to be added or attached to a kind of aromatic structure (that is made up of hydrogen) is said to be replaced by an electrophile.
