Hello!
In this case, for such calorimetry problem, we can notice that the combustion of the compound releases the heat which causes the increase of the temperature by 11.95 °C, it means that we can write:
In such a way, we can compute the total released heat due to the combustion considering the calorimeter specific heat and the temperature raise:
Next, we compute the molar heat of combustion of the compound by dividing by the moles, considering 1.400 g were combusted:
Thus, we obtain:
Best regards!
Titration is a technique for determining unknown molarity of acid by adding a base of know malarkey to a known volume of acid
The process of calculating the quantity of a material A by adding measured increments of substance B, the titrant, with which it reacts until exact chemical equivalency is obtained (the equivalence point)" is the definition of titration. Titration, commonly referred to as titrimetry, is a method of chemical qualitative analysis used to determine the concentration of a certain analyte in a mixture. The goal of titration is to identify the equivalence point, or the point at which chemically equivalent amounts of the reactants have been combined, which is a key analytical chemistry technique also known as volumetric analysis. The stoichiometry of the reactants determines how many reactants have been mixed at the equivalence point.
