Answer:
589.8 kJ/mol
Explanation:
Let's consider the process in which <em>the most loosely bound electron from each atom in a mole atom of gaseous calcium is removed.</em>
Ca(g) + Energy ⇒ Ca¹⁺(g) + 1 e⁻
The energy involved in this process is known as First Ionization Energy. The First Ionization Energy for calcium is 589.8 kJ/mol.
Answer:
The answer is D. Substances Y and Z would react to replace substance W, and the position of equilibrium would shift to the left.
Explanation:
PLZ BRAINLIEST'!!!
When Ka =1.37 x 10^-4
∴Pka = - ㏒Ka
= -㏒ 1.37 x 10^-4
= 3.86
According to H- H equation:
when PH = PKA + ㏒[conjugate base / weak acid]
when the lactate is the conjugate base and lactic acid is the weak acid
∴ PH = Pka +㏒[lactate] / [lactic acid]
so, by substitution:
4.49 = 3.86 + ㏒[lactate]/[lactic acid]
∴[lactate]/[lactic acid] = 4.3
∴ [lactic acid] / [lactate] = 1/4.3
= 0.23
Answer: 1 dissociation. 2. Hydration. 3. Dissolving.
