<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>

$\huge\boxed{\text{London / Van de Waals}}$

<h2>_____________________________________</h2><h2> $\huge\textbf{Van de Waals}$ </h2>

London Dispersion force or Van de waals force is a temporary attractive force which are the weakest and occur between nonpolar noble gases and same charges. This force is weaker because they have more electrons that are farther from the nucleus and are able to move around easier.

<h2>_____________________________________</h2><h2> $\huge\textbf{Dipole-Dipole}$ </h2>

Dipole force is present between the polar molecules. Polar molecules are those molecules which have slightly negative and slightly positive charge. Dipole-dipole forces are attractive forces between the positive end of one polar molecule and the negative end of another polar molecule.

<h2>_____________________________________</h2><h2> $\huge\textbf{Hydrogen Bonds}$ </h2>

It is a special type of dipole force present between polar molecules, it is formed between Hydrogen atom which forms positive ion, and the other negative ion. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom. The hydrogen bond is one of the strongest intermolecular attractions, but weaker than a covalent or an ionic bond.

A biologist working in a lab adds a compound to a solution that contains an enzyme and substrate. This particular compound binds

ad-work [718]

Answer:

Adding more substrate would overcome the effect of the compound

Explanation:

Enzymes are biochemical catalysts that speed up chemical reactions. They act on specific substrate to convert them to products.
Compounds known as inhibitors slow down the rate of enzyme activity.
Inhibitors are classified as competitive and non-competitive inhibitors.
Competitive inhibitors will compete with the substrate to bind the active sites on the enzyme. The effect of competitive inhibitors may be reduced by increasing the concentration of the substrate.
The compound added by the biologist was a competitive inhibitor and therefore adding more substrate would overcome its effect on enzyme catalysis
Non-competitive inhibitors binds the active site of the enzyme permanently and prevents the substrate from accessing the active sites.

what is the maximum number of covalent bonds that an oxygen atom with atomic number 8 can make with hydrogen? question 4 options

Oliga [24]

Maximum number of covalent bonds that an oxygen atom can make with hydrogen is 2.

the ground state electronic configuration of oxygen is 2s² 2p⁴ that means it has 6 electrons in its valence shell and require two electrons are required to complete its octate.
Two bonds are created when an electron donor atom shares the two needed electrons with oxygen. The ability of two oxygen atoms to share valence electrons results in the creation of a double bond between the two atoms.
There are no longer any empty orbitals in the octet of oxygen after it is complete. As a result, it is unable to accept more electrons or create more bonds.

Therefore, Oxygen can only generate two bonds because it needs two additional electrons to complete its octet, after which it will run out of empty orbitals in which to receive additional electrons and create additional bonds.

what actually is left over of water once it self ionizes? Like what exactly are the hydrogen and hydroxide ions? Do they remain

GrogVix [38]

The formula for the self ionization of water is 2H₂O(l)⇄H₃O⁺(aq)+OH⁻(aq)

The hydronium (H₃O⁺) is usually just referred to as a hydrogen ion or a proton (H⁺) and hydroxide (OH⁻) doesn't have another name that I am aware of. These ions do stay in solution. However the concentrations are really small and the equilibrium constant (K(w)) is 1×10⁻¹⁴.

I hope this helps. Let me know if anything is unclear.
