    Step 1: Write the number of atoms of each element. H 2 (g) Hydrogen + Cl 2 (g) Chlorine → HCl (g) Hydrogen chloride. From the table, it is clear that the atoms of hydrogen and chlorine are not balanced. Step 2: Balancing the unbalanced atoms. In order to balance the equation, we will make the coefficient of HCl as 2. Now the equation becomes.

    Solution. Starting with a known amount (1.00 L of isooctane), we can perform conversions between units until we arrive at the desired amount of heat or energy. The enthalpy of combustion of isooctane provides one of the necessary conversions. Table \ (\PageIndex {1}\) gives this value as −5460 kJ per 1 mole of isooctane (C 8 H 18).

    Calcium carbonate reacts with dilute hydrochloric acid to give a solution of calcium chloride, carbon dioxide gas and water. Write the equation for this. You have to know that dilute hydrochloric acid is a solution of hydrogen chloride in water. For equation purposes, you can just write this as HCl.
