Answers
Hey mate hope it helps you..
1. symbolic representation of a chemical reaction in the form of symbols and formulae, wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side.
2. heat is released in the process . hence it is an exothermic process
3. The physical state of reactants and products Hence, the symbols 's' for solid, 'l' for liquid, 'g' for gas and 'vap' for vapour are added. Conditions such as temperature, pressure and catalyst affecting the reaction.
4. a. H2S + SO2 ----> S + H2O
b. Bacl2 + H2SO4 -----> BaSO4 + Hcl
