Answer:

the correct option is B

Explanation:

The correct option is b, since if we reach pH 7, it means that the acid-base reaction is neutralized, therefore the base has been neutralized by an acid or vice versa, without taking into account the proteins or the amounts of both components .

Answer:

E) None of the above is true

Explanation:

A) is wrong. The unit for amount of substance is the mole. The moles of acid equal the moles of base only when the molar ratio is 1:1. If the molar ratio is different, you will use different moles of acid and base used to reach the equivalence point.

B) is wrong. The pH = 7 only for a strong acid-strong base titration. If you have a weak acid or base, the pH at the equivalence point will not be 7.

C) is wrong. An indicator is pH sensitive. It shows distinct colours in different pH ranges.

D) is wrong. A titration curve is a plot of pH vs. the volume of titrant.

Why do atoms separate in molecules
N76 [4]

Answer:

Atoms form chemical bonds with other atoms when there's an electrostatic attraction between them. This attraction results from the properties and characteristics of the atoms' outermost electrons, which are known as valence electrons.

What is hydrogen bonding
yKpoI14uk [10]

Answer:

a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

Explanation:

For example, in water molecules (H2O), hydrogen is covalently bonded to the more electronegative oxygen atom. Therefore, hydrogen bonding arises in water molecules due to the dipole-dipole interactions between the hydrogen atom of one water molecule and the oxygen atom of another H2O molecule.
