NaOH is a hygroscopic compound, which means that it has a very strong affinity for water. Moreover, NaOH is also a stronger base than acetic acid is a strong acid. These two properties of NaOH make it necessary for different precautions to be taken while preparing a solution.
On the other hand, acetic acid is not very reactive and may easily be prepared in a solution of unboiled water.
Answer:
7.307 x 10^-23
Explanation:
mass of one molecule = mr/ avogadros number
= 44/6.022 x 10^23
= 7.307x 10^-23
<span>The enthalpy of the reaction in an aqueous
solution can be determined by taking the difference between the summation of
enthalpies of the products multiplied to their respective stoichiometric
coefficient and the summation of enthalpies of the reactants multiplied to
their respective stoichiometric
coefficient. In this case, the equation is -241(6) + -393.5 (5) -[-119.9] equal to 641.4 kJ </span>
It will form a tetraamminezinc sulphate and a blue solution will be formed...the reaction should be carried out in a fume chamber because a poisonous substance will be released to the atmosphere
