Similarly, strong bases like Calcium Hydroxide (Ca (OH)2), Lithium Hydroxide (LiOH), Potassium Hydroxide (KOH) and Sodium Hydroxide (NaOH) fully dissociate in an aqueous solution to give hydroxyl ions. The Brönsted-Lowry theory gave a more comprehensive definition of acids and bases, stating...
The branch of chemistry that deals with the changes of energy and heat of a system is referred to as thermodynamics. It tells about the conversion of thermal energy into various types of energy and how it can be affected.Answer and Explanation: Enthalpy Enthalpy is a thermodynamic term which...
What is the change in enthalpy for the reaction HCl + NaOH gives NaCl + H2O, in kJ/mol, calculated using Hess's Law with the given values for the enthalpy of formation of each compound (HCl, NaOH, NaCl, and H2O)? Use Hess's Law and a table of he...
Calculate the standard enthalpy change (in kJ/mol) for each of the following reactions. (a) Ni(s) + Cl2(g) \rightarrow NiCl2(s) ; [{Blank}] kg/mol (b) Al2O3(s) + 3 H2(g) \rightarrow 2 Al(s) + 3 H2O(l) ; [{Blank}] kg...
