In the given reaction mechanism, there are three reaction intermediates.

The intermediates are species that are formed during the reaction but are not the final products.

They are typically involved in subsequent steps of the reaction.

The reaction intermediates in the provided mechanism are:

(CH3)3CCl-: This is formed as an intermediate in the first step of the mechanism,

where (CH3)3CCl undergoes dissociation to give (CH3)3CCl- and a chloride ion (Cl-).

(CH3)3CHOH: This intermediate is formed in the second step of the mechanism.

(CH3)3CCl- reacts with water (H2O) to produce (CH3)3CHOH, also known as tertiary butyl alcohol.

Explanation:

Nitric acid, HNO3(aq), breaks up into ions (a cation and an anion) in a water solution.

After the chemicals had a chance to react, the components HBr, H₃O⁺, Br⁻, & H₂O will anticipate being present in the beaker. Hence, the correct choice is option D.

Generally, water and the diatomic molecule hydrogen bromide (HBr) combines together to form the caustic acid also known as hydrobromic acid. The pH of HBr is usually 0.21. Generally a very acidic environment with corrosive liquid (HBr) are produced when an extremely poisonous and miscible in water gets compressed gases bromine is dissolved into the water.

Generally, HBr is soluble in water because of its ability to form interparticle hydrogen bonds with water. In HBr, usually a dipole forms because of the disparity in electron density between H and Br. Hence, option D is correct.

Analyzing a company's "acid test" ratio is one way in which an investor can tell if the company can pay off its short-term debts if there is a drop in sales revenue.

The acid test ratio, also known as the quick ratio, measures a company's ability to meet its immediate financial obligations without relying on the sale of inventory. It is calculated by dividing the sum of a company's cash, cash equivalents, and accounts receivable by its current liabilities. A higher acid test ratio indicates a greater ability to cover short-term debts, which is particularly important during times of reduced sales revenue.

Given what we know about lab safety, we can confirm that the best way to smell a chemical sample when needed, is to place the sample under your nose at a safe distance and smell very slowly.

Many chemicals can at times emit relatively toxic fumes. These fumes can be very dangerous to inhale. Therefore, it is best to take safety precautions when attempting to smell a sample. Placing the sample at a distance and smelling slowly is a good habit as it gives you time to react to an unpleasant or potentially dangerous smell.

Therefore, we can confirm that since many chemicals in a lab can be dangerous and can often have relatively toxic fumes, extreme care should be taken if attempting to smell them. Placing the sample at a safe distance and smelling slowly is a good safety precaution to take.

Periodic table is a tabular arrangement of elements in the form of a table. In the periodic table, elements are arranged according to the modern periodic law which states that the properties of elements are a periodic function of their atomic numbers.

It is called as periodic because properties repeat after regular intervals of atomic numbers . It is a tabular arrangement consisting of seven horizontal rows called periods and eighteen vertical columns called groups.

Elements present in the same group have same number of valence electrons and hence have similar properties while elements present in the same period show gradual variation in properties due to addition of one electron for each successive element in a period.

0.009 mol/L

Explanation

Given:

Mass of KCl = 0.66 g

Volume of water = 700 mL = 0.7 L

From the periodic table: 1 mol K = 39.10 g; 1 mol Cl = 35.453 g

What to find:

The molarity of the solution

Step-by-step solution:

The formula to calculate molarity is:

The first step is to calculate the molar mass of KCl

KCl = Mass of 1 mol K + Mass of 1 mol Cl

KCl = 39.10 g + 35.453 g

KCl = 74.553 g

So the molar mass of KCl = 74.553 g/mol

The next step is to determine the number of moles of KCl in 0.66g of KCl:

Put the values of mole and volume into the molarity formula above to determine the molarity of the solution:

Answer:

Negative, because the potential energy of the reactants is higher than the potential energy of the products

Explanation:

Exothermic reaction is a reaction in which heat is released to surrounding. This is due to the fact that the heat content of the reactant is higher than the heat content of product thus producing a negative enthalpy change (ΔH) i.e

Enthalpy change = Heat of product – Heat of reactant

ΔH = Hp – Hr = negative

Considering the options given in the question above, the correct answer is:

Explanation:

The final temperature of the system has been 130\(\rm ^\circ C\).

Specific heat can be defined as the amount of heat required to raise the temperature of 1 g of substance by 1-degree celsius.

The amount of heat lost and the heat gained have been equal.

Heat = mass × specific heat × change in temperature

Thus,

mc\(\Delta\)T = mc\(\Delta\)T

50 g × (10 - x) = 120 × (x - 80)

500 - 50x = 120x - 9600

70x = 9100

x = 130

Thus, the final temperature of the system has been 130\(\rm ^\circ C\).

Algae blooms are most often caused by eutrophication.

Algae blooms are are dense layers of tiny green plants that occur on the surface of lakes and other bodies of water when there is an overabundance of nutrients (primarily phosphorus) on which algae depend.

Algae species tend to proliferate in growth (bloom) in the presence of abundance nutrients. This abundance of nutrients is as a result of a process called eutrophication.

Eutrophication is the ecosystem's response to the addition of artificial or natural nutrients, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system.

Oxidation D) occurs when the electrons are lost from an atom or compound. Oxidation refers to a chemical reaction where there is a transfer of electrons from one substance to another.

During oxidation, the substance that loses electrons is known as the reducing agent while the substance that gains electrons is known as the oxidizing agent. When an atom or compound loses electrons during oxidation, it becomes more positively charged, and this results in a decrease in its negative charge.

For example, when iron rusts, it undergoes oxidation as it loses electrons to oxygen. The iron atoms lose their electrons, and as a result, they become positively charged. This causes the iron compound to have a more positive charge than it did before the oxidation process.

In summary, oxidation occurs when electrons are lost from an atom or compound, which results in a decrease in the negative charge of the compound or atom.
