Calcium carbonate is a metal carbonate. When an acid reacts with dilute hydrochloric acid and forms carbon dioxide gas & solution of calcium chloride. Reaction: CaCO3 + 2HCl(a) = CaCl2 + H2O(l) + CO2(g) Change in Free Energy: ΔG(20C) = -25.2kJ (negative, so the reaction runs) Change in Enthalpy: ΔH(20C) = +79.9kJ (positive, so the reaction is endothermic)

How to find Bond Order in 1 minute Bond Order is the number of bond between a pair of atoms. Example N2 has three bond order because between N there are three bond. But if you are not able to draw the structure then calculate no of electrons of the compound.

Concise Inorganic Chemistry: Fifth Edition by J.D. Lee Paperback – Feb 2008 by J.D. Lee (Author) Concise Inorganic Chemistry Concise Inorganic Chemistry is ideal for all those students who are looking to study Inorganic chemistry in much more detail and understand the basics of each and every concept thoroughly. It is not just a collection of theoretical text; rather information given in the book is backed by proper reasoning or experiments. Full effort has been made to keep the language as simple as possible, so that it can be of use to all. This book is designed in such a way that it caters to all the questions that a student may have from inorganic chemistry. The book is divided into six parts so that the readers find it easy to locate their answers. Special attention has been given to the different blocks of the periodic table, so there are parts such as s-block, p-block and other bocks as well, hydrogen and other topics. It is continuously updated keeping in mind the
