The strongest type of interaction that occurs between the atoms is hydrogen bond.(option c)

A hydrogen atom that is bound to a highly electronegative atom and another highly electronegative atom that is close by interact with one another to form hydrogen bonds, which are an unique kind of attractive intermolecular interactions. This process is known as hydrogen bonding.

As a result of hydrogen bonding, a hydrogen atom simultaneously forms a covalent bond with one electronegative atom and a hydrogen bond with the other. These are the prerequisites for hydrogen bonding:

1.A strongly electronegative atom connected to the hydrogen atom must be present in the molecule. The degree of polarization of the molecule increases with increasing electronegativity.

2.The electronegative atom should have a tiny size. The strength of the electrostatic attraction increases with decreasing size.

So, the hydrogen bonding is the strongest bond.

Enzyme Inhibitors bind to an enzyme to turn it off, thus preventing it from catalyzing a reaction.

An enzyme is a biological molecule that catalyzes chemical reactions in the cell. Enzymes work by lowering the activation energy required for a reaction to occur, making it more likely that the reaction will proceed. However, enzymes can also be inhibited, which means that their activity is reduced or stopped completely. This can happen for a variety of reasons, such as the presence of a specific molecule called an inhibitor.

Some inhibitors bind to the active site of the enzyme, preventing the substrate from binding and thus preventing the reaction from occurring. Other inhibitors bind to other parts of the enzyme, causing a conformational change that prevents the enzyme from working. Still, other inhibitors bind to enzymes and alter their activity by non-covalent interactions.

There are different types of inhibitors like competitive inhibitors bind to the active site of an enzyme and prevent substrate binding. Non-competitive inhibitors bind to a different site on the enzyme, causing a conformational change that makes the enzyme less active. Feedback inhibitors bind to the end product of a metabolic pathway, inhibiting the enzyme that catalyzes the first step of the pathway.

Answer:

4 molecules of carbon dioxide (CO₂) and 4 molecules of water (H₂O)

Explanation:

The unbalanced chemical equation is:

C₄H₈ + 6 O₂ →  CO₂ +  H₂O

To balance the equation, we have to write a coefficient of 4 for CO₂ and a coefficient of 4 for H₂O, as follows:

C₄H₈ + 6 O₂ → 4 CO₂ + 4 H₂O

Now, we can see that 4 molecules of carbon dioxide (CO₂) and 4 molecules of water (H₂O) are produced for each molecule of C₄H₈.

When two atoms of chlorine and iodine join together to form a covalent bond, their outermost electrons interact to form a chemical bond.

What is a Covalent bond?

A covalent bond is a type of chemical bond that involves the sharing of a pair of electrons between two atoms. Covalent bonds are formed when two atoms come together to share their electrons in order to reach a more stable electron configuration. As a result, the two atoms become bonded together by the attraction of their shared electrons.

The chlorine atom has seven valence electrons, while the iodine atom has seven as well. Both atoms will want to complete their octets, so the two atoms share their outermost electrons with each other. During the formation of the covalent bond, the chlorine atom will donate one of its electrons to the iodine atom, while the iodine atom will donate one of its electrons to the chlorine atom. This sharing of electrons allows the two atoms to form a single bond and fill their octets, forming a covalent bond.

Kinetic energy increases as mass increases

The shape of the mass vs energy graph shows a linear relationship

When we double the mass, we double the energy.

The graph shown in the image is a plot of the kinetic energy of objects on the y-axis and the mass of the objects on the x-axis.

The graph is a straight line. This shows that there is a linear relationship between the two parameters - the kinetic energy and mass of objects. Thus, the kinetic energy increases as mass of objects increases, and decreases as mass of objects increases.

From the graph, when the mass of objects are doubled, there is also a double in the amount of the kinetic energy of objects.

Explanation:

In the case of water.

The frequency of a photon with an energy of 4. 26 x10-19 J and a wavelength of 4. 67 x 10-7m.  [E= 6. 626 x 1034 x frequency C(3. 0 x 108 m/s) = wavelength x frequency] is 28.22 × 10¹⁵hz.

So formula is :-

Energy of photon, E=hc/λ  or λ=hc/E

E = hν = hc/λ,

Where, h=6.626×10−³⁴Js,c=3×10⁸

By putting all these values, we get:-

4.26× 10-¹⁹ = 6.626×10-³⁴ × ν
