CALORIMETRY PROBLEM: PART: SOLVING FOR ENTHALPY OF THE REACTION:SUBPART: SOLVING FOR THE MOLES OF THE REACTANTS AND IDENTIFYING WHICH IS THE LIMITING REACTANT. Reaction:X(OH)3 + 3HCI -> XCL3+ 3H20 (X IS AN IMAGINARY ELEMENTONLY) I'LL BE GIVING TWO SOLUTIONS FOR FINDING THE LIMITING REACTANT, PICK ONE WHICH IS THE CORRECT SOLUTION AND PLEASE EXPLAIN WHY. First Solution: 1 mol XC13 (0.500 L)1 moi X(OH)3/ ,0.250 mol X(oh)3. 1. Mol X(ОН)3 3D 1 L .0.175mol HCI 2. Mol HCI= ( (0.750 L) (1 тoi XC13 1 L 3 mol HCI Second Solution: ,0.250 mol X(oh)3. (0.500 L) 1moi X(OH)3) 3 тоi Н20 1. Mol X(ОH)з 3D 1 L 0.175 mol HCI ,3 тоi H20 2. Mol HCl= ( (0.750 L) ( 1 L 3 mol HCI Answers will differ depends on the solution used, so I need to know which is the correct way. I don't need the answer, which is the limiting reactant, just tell me which of the solution should I use to find it. Basically, I don't know if I should ratio the reactants to H20 or to XCI3 since they are both products.
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
