Answer:1.59
Explanation: For every mol of Ca(OH)2 there are two moles of OH so the concentration of OH is .013 x2 =.026 M OH
pOH = - log [OH] so -log .026 = 1.59
Answer: Option (a) is the strong acid.
Explanation:
Hydrochloric acid is a strong acid and when it is added to water then the following reaction takes place.
where, is a conjugate acid and is a conjugate base.
Therefore, when we add HCl into water then it dissociates completely into hydronium ion and chlorine ion.
Thus, we can conclude that a strong acid is disassociated completely, producing more conjugate base.
The value or amount of heat that is needed in order to vaporize the given amount of methanol (CH3OH) can be calculated through the equation,
H = (n)(hf)
where H is the amount of heat
n is the given amount in mol, and
hf is the molar heat of vaporization
Substituting the known values,
H = (2.15 mol CH3OH)(71.8 kJ/mol)
H = 154.37 kJ
<em>ANSWER: 154.37 kJ</em>
