<span>Beryllium
This is because it is in a group where Alkaline earth metals are but does not exhibit true properties of elements in that group as It exhibits amphoteric properties showing both the properties of a base and that of an acid.</span>

Answer:
158.35 K
Explanation:
Using the general gas law
P₁V₁/T₁ = P₂V₂/T₂ where P₁ = 150.4 kPa, V₁ = 12.2 L, T₁ = 22.7 °C = 273 + 22.7 = 295.7 K, P₂ = 101.3 kPa, V₂ = 9.7 L and T₂ = unknown.
Making T₂ subject of the formula, we have
T₂ = P₂V₂T₁/P₁V₁
Substituting the values of the variables into the equation, we have
T₂ = P₂V₂T₁/P₁V₁
T₂ = 101.3 kPa × 9.7 L × 295.7 K/150.4 kPa × 12.2 L
T₂ = 290,557.777 K/1,834.88
T₂ = 158.35 K
A strong acid must have a weak conjugate base and a weak acid must have a strong conjugate base. The reason behind this is simple.
A "strong" acid or base is actually one that is unstable and will readily dissociate when added to water. A "weak" acid or base is one that is stable, and does not dissociate in water.
If an acid is to be "strong", it must readily dissociate to release hydrogen ions. However, the conjugate base that is formed must also be stable, so that is does not combine back with the released hydrogen ions, making it a weak base.
