steps altogether. Consider a double replacement reaction between Zinc (ll) chloride and sodium hydroxide: ZnCl2+NaOH ==> Complete the chemical equation by: Step 1: Instead of just writing the product formulas, I would like you to rewrite the entire equation. So write out the reactants provided and the products you predict. Step 2: Balance the equation. Show work. Step 3: Add subscripts (aq, I, s, or g) to show how the reactants combine and which product will precipitate to be collected as a solid. Step 4: Provide subscripts for both reactants and 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.
Break each step down. You should have four steps altogether.

1.Double displacement reaction are those in which one of the atom in one reactant is replaced by one of the atom in other reactant .
2. It is also called metathesis.
