Functions

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.

Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input. The general representation of a function is y = f(x).

An example of a simple function is f(x) = x2. In this function, the function f(x) takes the value of “x” and then squares it. For instance, if x = 3, then f(3) = 9.

The first step of an enzymatic reaction is, substrate molecule (S) collide with enzyme(E) and react to form an intermediate compound called the enzyme-substrate (E–S) complex.

Enzymatic catalysis of a reaction between two substrates. The enzyme provides a template on which the two substrates are brought together in the correct position and orientation to react with each other. Enzyme-catalyzed reactions take place in at least two steps.

In the first step, an enzyme molecule (E) and a substrate molecule or molecules (S) collide and react to form an intermediate called an enzyme-substrate (E–S) complex. (This step is reversible, as the complex can dissociate into the original substrate or substrates and the free enzyme.) Once the E–S complex is formed, the enzyme is able to catalyze the formation of the product (P), which is then released from the enzyme surface:

Answer:

hydrogen gas and chlorine

Explanation:

HCl is a chemical compound and aqueous solution form of HCl is a homogeneous solution

All the following are homogeneous mixtures except hydrogen gas and chlorine gas. Therefore, option A is correct.

A mixture is said to be homogeneous if its composition is constant throughout. Because the dissolved salt is evenly distributed throughout the whole salt water sample, the salt water described above is homogeneous.

It is single in composition throughout. There is only one phase of matter observed in a homogeneous mixture.

In an aqueous solution of hydrogen chloride gas, water serves as the solvent and the solute, respectively. Hence, hydrogen chloride is a homogeneous mixture rather than a compound.

When hydrogen chloride is dissociated and solvated in water to create hydrochloric acid, it counts as a homogeneous mixture.

Acid in lemon juice reacts with metal containers to produce harmful chemicals. As a result, lemon juice is not kept in such containers.

What  is Acid ?

Acidic substances are typically easy to recognise by their sour flavours. A molecule that can donate an H+ ion and keep its energetic favorability even after losing H+ is a basic definition of an acid. Blue litmus paper is known to turn red when exposed to acids.

Bases, on the other hand, have a smooth consistency and a bitter flavour. A base that may dissolve in water is known as alkali. When these substances interact chemically with acids, salts are created. Red litmus has a history of becoming blue on bases.

The definitions of the terms acid and base vary depending on how one chooses to see the properties of acidity and basicity.

Lemon juice has a strong acidic flavor and can react with some metals. Lemon juice can corrode or rust metal when it comes into touch with it. This is so that iron oxide, a new chemical created by the reaction between the metal and the acid in lemon juice, can be formed.

Reddish-brown iron oxide is a less powerful material than pure iron. Iron oxide will keep combining with oxygen in the air over time to coat the metal in a thick film of rust.

Starch is a complex carbohydrate that is a polymer of sugar molecules. The sugars in starch have OH bonds that can interact and stick together through a process known as hydrogen bonding.

A hydrogen bond is an electrostatic force of attraction between a hydrogen atom covalently bound to a more electronegative "donor" atom or group and another electronegative atom bearing a lone pair of electrons—the hydrogen bond acceptor—in chemistry.

Hydrogen bonding is not a covalent bond to a hydrogen atom, but rather a type of dipole-dipole attraction between molecules. The attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as an N, O, or F atom and another very electronegative atom causes it. Because hydrogen bonds have the strongest permanent molecular dipoles of any covalent bond, they have the strongest intermolecular forces for covalent compounds.

The compound cobalt(II) nitrate, Co(NO3)2 is soluble in water. The net ionic equation for the dissociation reaction is Co(NO3)2 (s) = CO2+(aq) + Na3(aq) + PO4-(l).

In general, during the dissociation process in chemistry, molecules (or ionic compounds like salts, or complexes) separate or divide into different entities like atoms, ions, or radicals. This procedure is typically reversible. For instance, the covalent bond between an electronegative atom and a hydrogen atom is broken when an acid dissolves in water due to heterolytic fission, in a reaction which releases a proton (H+) and a negative ion. Dissociation is the antithesis of connection or recombination. Separation of the anions and cations occurs when salts are dissociated by solvation in a solution, such as water. The solvent can be evaporated in order to recover the salt. A substance that has free ions and can be employed as an electrically conducting medium is referred to as an electrolyte. In a weak electrolyte, the majority of the solute does not dissolve, whereas in a strong electrolyte, a higher proportion of the solute dissociates to generate free ions. A weak electrolyte is a material whose solute primarily occurs in solution as molecules (which are referred to as being "undissociated"), with a very tiny amount existing in solution as ions.

Explanation:

The component elements of a compound can only be separated via a chemical reaction that breaks the atomic bonds that bind its molecules. Also, compounds are formed by 2 or more different elements.

1) The energy level of the electron

2) The symbol is n

3) The shells correspond to the energy levels

4) The 4th shell has more energy than the 3rd shell

We know that the term quantum number has to do with the position of the electron in the atom. According to the Bohr model of the atom, the electrons that are found in the atom are said to have a specific energy and the electron can move from a lower to a higher energy level by the absorption of energy.

Given the fact that the principal quantum number can also be designated as energy levels or shells, we know that all the electrons that can be found in the atom are said to be classified into certain specific principal quantum levels.

The solution by dividing the number of moles of urea by the volume of the solution 0.637 M.

Molarity is a unit used to measure the concentration of a solution. It is defined as the number of moles of a solute per liter of a solution.

The molarity of a solution can be calculated by dividing the number of moles of solute by the volume of the solution. In this case, the solute is urea (NH2CONH2) and the volume of the solution is 203 grams of water.
To calculate the molarity of the solution, we first need to calculate the number of moles of urea present in the solution. This can be done by using the formula:
Moles of urea = (mass of urea (g))/(molecular weight of urea (g/mol))
Therefore, the number of moles of urea present in the solution is:
Moles of urea = (7.78 g)/(60.06 g/mol) = 0.129 moles
Now, we can calculate the molarity of the solution by dividing the number of moles of urea by the volume of the solution (in liters):
Molarity = (0.129 moles)/(0.203 liters) = 0.637 M
