Cyclic bromonium ion is the reactive intermediate that is formed in the reaction of an alkene with br2 and water. the correct answer is option(d).
A reactive intermediate is a highly reactive, high-energy, brief-lived molecule that, when produced in a chemical reaction, will swiftly transform into a stable molecule. They may occasionally be divided and stored. For instance, low temperatures and Matrix Isolation. Carbocations, carbanions, free radicals, carbenes, nitrenes, and benzyne are six different categories of reaction intermediates. These intermediaries are frequently produced when a chemical substance is chemically broken down.
Reactive intermediates can be used to explain the process of a chemical reaction. Reactive intermediates are high-energy, stable products that are present only in one of the intermediate phases of most chemical reactions, which typically involve more than one elementary step.
The complete question is:
What type of reactive intermediate is formed in the reaction of an alkene with Br2 and water to give a bromohydrin?
a.carbocation
b.carbanion
c.radical
d.cyclic bromonium ion

Answer: negatively charged; positively charged electrode.
Explanation:
Electrophoresis can de defined as the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field. The electrophoresis of negatively charged particles is called anaphoresis while the electrophoresis of positively charged particles is called cataphoresis.
During proten electrophoresis, due to electric field, proteins migrate through pores in a polyacrylamide gel matrix. It must be noted that pore size decreases with increasing acrylamide concentration.
Proteins set up at a buffer pH of 8.6, the proteins will become negatively charged (that is, anions) and it will move to the positively charged electrode.
Answer:
<h2>14.85 moles </h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>14.85 moles</h3>
Hope this helps you
The pressure of the oxygen gas collected : 718 mmHg
<h3>Further explanation</h3>
Given
P tot = 748 mmHg
P water vapour = 30 mmHg
Required
P Oxygen
Solution
Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases
Can be formulated:
P tot = P1 + P2 + P3 ....
The partial pressure is the pressure of each gas in a mixture
P tot = P H₂O + P Oxygen
P Oxygen = 748 mmHg - 30 mmHg
P Oxygen = 718 mmHg
