Answer:

We can do the nitration of benzene by treating the benzene with a mixture of nitric acid and sulphuric acid by not extending the temperature of 50°C

Explanation:

Nitration of benzene takes place by treating the benzene with a mixture of nitric acid and sulphuric acid at low temperatures such as the temperatures below 50°C

The nitration of benzene takes place through electrophilic substitution reaction

In this reaction the electrophile is nitronium ion (NO2+) which performs an electrophilic substitution reaction on the benzene ring and during the reaction an intermediate will also be formed in which there will be positive charge distributed in the benzene

These electrophile is generated when nitric acid is treated with sulphuric acid

As nitric acid is a strong oxidising agent, here in this case the oxidation state of nitrogen will change from +5 to +3

Identify the conjugate base in the equation below

givi [52]

Answer:

a. CH3COO⁻.

Explanation:

Hello there!

In this case, according to the given ionization reaction of acetic acid:

CH₃COOH + H₂O --> H₃O⁺ + CH₃COO⁻

Whereas we can evidence how the CH₃COOH is the acid whereas H₂O the base, as the former donates H ions to the latter, which accepts them; we can infer that H₃O⁺ is the conjugate acid, resulting from the base and the a. CH3COO⁻ is the conjugate base, resulting from the acid.

Best regards!

You shine a flashlight into a glass of apple juice. Some of the light bounces off the liquid. Some of it passes through it. Whic

Vilka [71]

Answer:

2. Translucent

4. Reflection

Explanation:

The terms translucent describes the nature of the juice and reflection perfectly fits the property of the light.

A translucent substance is one that partially allows light to pass through it. Since it is said that some of the light bounced back and some passed through, this is translucent.

Also, the light bouncing back is an indicator of reflection. Reflection is a property of light where it bounces back a surface.

In the biosphere, prey represent a food source for predators. An increase in the population of prey means more food for predator

mote1985 [20]

<h2>Answer:</h2>

An increase in the population of prey means more food for predators, which will<u> increase</u> the predators' population. As a result, many more prey will be hunted, causing the prey population to<u> decrease.</u> In response, the predator population will <u>decrease</u>, resulting in an increase in the prey population.

<h3>Explanation:</h3>

The feedback loop is control of the system containing the prey and predator.

In this loop, the population of predator is directly proportional to prey but the population of prey is inversely proportional to a predators population.

As the population of prey increases, the population size of predator becomes large due to the availability of food. This inversely decreases the population of prey, as the predator do more hunt.

So the decrease in prey population results in a decrease in the predator population.
