Answer:
well I think the answer is it depends on the friction
Both joules and kilocalories are units of measurement for energy. This means that the solution to this problem can be solved just by converting the units using the appropriate conversion factors. One kilocalorie is equal to 4,184 joules. Multiply 0.5720 kcal by 4,184 to get the value in joules. This gives 2,393.25 joules.
Answer:
<em>The pKa is 13.0.</em>
Explanation:
pKa + pKb = 14
Given, Kb of trimethylamine = 6.3 × 
pKb = - log (6.3 × )
= 1.0
⇒ pKa = 14 - pKb = 14 - 1.0
<u>pKa = 13.0</u>
<em><u></u></em>
<em>Check: For most weak acids, pKa ranges from 2 to 13.</em>
