A chemical that bonds to the active site of an enzyme, thus blocking its function, is known as a competitive inhibitor.

A competitive inhibitor is a type of inhibitor that binds to the active site of an enzyme, preventing the substrate from binding and blocking the enzyme's function.

The active site is the specific region of the enzyme where the substrate binds and undergoes a chemical reaction.

By occupying the active site, the competitive inhibitor competes with the substrate for binding, reducing the enzyme's catalytic activity.

The term "competitive" refers to the competition between the inhibitor and the substrate for binding to the active site.

When the concentration of the competitive inhibitor is high, it becomes more likely to bind to the active site, reducing the availability of the active site for the substrate.

However, the binding of a competitive inhibitor can be reversed by increasing the substrate concentration, as it can outcompete the inhibitor and regain access to the active site.

Competitive inhibitors are important in understanding enzyme kinetics and designing drugs that target specific enzymes.

By selectively blocking enzyme activity, competitive inhibitors can regulate biological processes and serve as potential therapeutic agents.

An aqueous solution with a total volume of 1.00 L is prepared by dissolving 0.00113 mol of Ni(NO3)2 and 0.484 mol of NH3.

To analyze the solution, we need to consider the chemical reaction that occurs between Ni(NO3)2 and NH3. In aqueous solution, Ni(NO3)2 dissociates into Ni2+ ions and NO3- ions, while NH3 acts as a base and forms NH4+ ions and OH- ions. The reaction can be represented as:

Ni(NO3)2 + 6NH3 → [Ni(NH3)6]2+ + 2NO3-

Since 0.00113 mol of Ni(NO3)2 is present, it will react with an equivalent amount of NH3 to form [Ni(NH3)6]2+ ions. Therefore, the limiting reactant is Ni(NO3)2, and the amount of [Ni(NH3)6]2+ ions formed will be determined by the moles of Ni(NO3)2.

As each Ni(NO3)2 reacts with 6 moles of NH3 to form one [Ni(NH3)6]2+ ion, the number of moles of [Ni(NH3)6]2+ ions formed will be 0.00113 mol.

To calculate the concentration of [Ni(NH3)6]2+ ions in the solution, we divide the number of moles by the total volume of the solution:

Concentration = (0.00113 mol) / (1.00 L) = 0.00113 M

Therefore, the concentration of [Ni(NH3)6]2+ ions in the solution is 0.00113 M.

The last number is the outermost energy level, so there are two electrons in the highest occupied energy level of barium .

The group number is always equal to the number of electrons on the outermost level. Since barium belongs to group 2, its highest energy level contains two electrons. Organic compound with the formula, barium is an element with the symbol Ba and atomic number 56. Since barium is not ever found in nature as a free metal, it is the fifth element in group 2 and a soft, silvery alkaline earth metal. Witherite and baryte are two of the more typical barium minerals. Drilling mud is made by the use of barium compounds by the oil and gas sectors. By lubricating the drill, drilling mud makes drilling through rocks easier. Other products made with barium compounds include paint, rubber, bricks, tiles, and glass.

249 grams of potassium iodide (KI) should be used to prepare 0.600 of a 2.50 M solution of potassium iodide.

Molarity (M) is the amount of a substance in a certain volume of solution.

Molarity is defined as the moles of a solute per litres of a solution.

Molarity is also known as the molar concentration of a solution.

Given data:

Molarity of the solution = 2.50 M

Volume of solution = 0.600 L

Molarity =  \(\frac{Moles \;solute}{Volume \;of \;solution \;in \;litre}\)

Now putting the value in the equation:

2.50 M =  \(\frac{Moles \;solute}{ 0.600 L}\)

Moles of solute = 1.5

Moles  = \(\frac{mass}{molar \;mass}\)

1.5  = \(\frac{mass}{166.0028 }\)

Mass  = 249 gram.

Hence, 249 grams of potassium iodide (KI) should be used to prepare 0.600 of a 2.50 M solution of potassium iodide.

The statement that is not true for thermoplastic polymers is D) They have cross-linkage which breaks on heating.

Thermoplastic polymers are characterized by their linear molecular structure (A), which allows them to be melted and reshaped multiple times without significant degradation in properties. This is because their molecular chains can slide past one another when heated, leading to a softened or molten state (B). Once in this state, the polymer can be easily molded or extruded into various shapes (C) and will solidify upon cooling.

In contrast, thermosetting polymers exhibit cross-linking between their molecular chains, forming a three-dimensional network that provides strength and stability. This cross-linking prevents them from being remolded upon heating. Instead, thermosetting polymers undergo a curing process, where the cross-links are formed through heat or chemical reactions, rendering the material in a permanent, rigid state. Therefore, statement D is incorrect as it describes a characteristic of thermosetting polymers, not thermoplastics.
