<h3>An acid accepts H and removes them from a solution</h3>

When placed in water, acids, bases, and salts dissociate (separate) into electrolytes (ions). Salts dissociate into a cation (that is not H+) and an anion (that is not OH-), whereas acids and bases dissociate into H+ and an anion. An acid separates into anions and hydrogen ions (H+). Strong acids produce a high concentration of H+ by dissociating every single one of their molecules . Water-based solutions,

Acid:

When a material or chemical is in solution, it releases hydrogen ions (H+), which are known as acids. All hydrogen ions (H+) and chloride ions (Cl-), which are normally bound together by ionic bonding, dissociate (separate) in water when exposed to a strong acid like hydrochloric acid (HCl). Only some ions disintegrate into hydrogen ions (H+) and bicarbonate ions (HCO3-) in a weak acid like carbonic acid (H2CO3), while others are still bound together by ionic bonds.

Define base?

A base is a chemical that, when in solution, emits hydroxyl ions -{OH). We can also define a base as a substance that releases hydroxyl ions (OH-), which mix with any hydrogen ions (H+) in the solution to generate water molecules (OH- + H+ = H2O).

Therefore, a substance that receives or accepts hydrogen ions (H+) that are already present in the solution qualifies as a base.

Because it totally dissociates into sodium ions (Na+) and hydroxyl ions (OH-) when placed in water, sodium hydroxide (NaOH), which is a strong base, is now liberated and dissolves in water.

Briefly discuss three physical properties of ionic solids that are linked to ionic bonds.
ludmilkaskok [199]
Firstly, Ionic solids can't conduct electricity, this is because of the close packed structure partly caused by the strong attraction between the delocalised electrons and the positively charged ions in the lattice structure (the close packed structure is also partially due to the fact it is in a solid state, it's not just solely to the ionic bonds). As the structure is so close packed, the ions are not free to move so electricity cannot be conducted. 
Secondly, high melting and boiling points (counts as a physical property as it can be observed)  as there is high attraction between the oppositely charged entities in the ionic lattice, added to by the sheer number of ionic bonds and resulting electrostatic attraction in a lattice (aka strong and plentiful ionic bonds) mean lots of energy is needed to overcome these bonds in order to change state.
Thirdly, they are usually hard and brittle as the lattice is a huge structure that is held rigidly in place by the strong electrostatic attraction arising from the ionic bonds.

What does the steepness of the line on the graph represent?
hoa [83]

Answer:

The steepness of a hill is called a slope. The same goes for the steepness of a line. The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.

What is the angle between the phosphorus-fluorine bonds? (if there is more than one angle, pick the smallest.)
lorasvet [3.4K]

Between equatorial positions, the F-P-F angle is 120°, and between axial and equatorial positions, it is 90°.

<h3>What in chemical bonding is equatorial position?</h3>

Equatorial Organic Chemistry Illustrated Glossary. Equatorial: In cyclohexane, a bond that runs parallel to the ring's axis (i.e., it follows the chair's equator), or a group joined by such a bond. Positions A are axial, and positions E are equatorial.

<h3>Why do equatorial positions have greater stability?</h3>

As was said in the preceding section, the equilibrium favors the more stable conformer because the chair conformation, in which the methyl group is equatorial, lowers steric repulsion. All monosubstituted cyclohexanes share this property.
