Answer:
c Acid + base = conjugate base + conjugate acid
Explanation:
In a Bronsted-Lowry acid-base reaction, the original acid gives up its proton and becomes a conjugate base. In like manner, the original base accepts a proton and becomes a conjugate acid. For every acid, there is a conjugate base and for every base, there is a conjugate acid:
HA ⇄ H⁺ + A⁻
acid conjugate base
B + H⁺ ⇄ HB⁺
base conjugate acid
Answer:
Unit cells which are present per cubic centimeter of Ag =
Volume =
Edge length =
Explanation:
(a)
Given that:-
The density of the solid Ag = 10.5 g/cm³
Molar mass of silver = 107.8682 g/mol
So, Moles present per cm³ of Ag = =0.0973 mol/cm³
Also, 1 mole = atoms.
So,
Atoms present per cm³ of Ag =
Thus, answer =
In FCC, the number of atoms in the unit cell = 4 unit cells
So,
Unit cells which are present per cubic centimeter of Ag =
<u>Unit cells which are present per cubic centimeter of Ag = </u>
(b)
The reciprocal of the unit cell/cm³ is the volume of the unit cell.
So,
<u>Volume = </u>
(c)
Also, Volume =
Thus, edge length = =
<u>Edge length = </u>
What question would that be ?
Answer:
c. benzoic acid
Explanation:
The given reaction is an example of a Grignard reaction:
When chlorobenzene (C₆H₅Cl) reacts with Mg in ether, an intermediate is formed (C₆H₅MgCl).
Said intermediate then reacts with CO₂ producing a benzoic acid salt (C₆H₅CO₂X), this salt is then neutralized with dilute HCl producing benzoic acid (C₆H₅CO₂H).
Any positive number of Celsius is going to be above freezing. 0°C is the freezing point of water. 100°C is the boiling point of water. So 214°C is going to be extremely hot, as it is well above 400°F which is around the temperature many ovens use to cook food.
As for Neptune, what I could find out is the the surface is around negative 200°C which is extremely cold.
