which out of the four balanced chemical equations best represent the thermal decomposition of sodium bicarbonate. The guiding question will be answered with the outcome of the sodium bicarbonates thermal decomposition and it being plugged in into the four balanced chemical equations. John Dalton atomic theory explains two fundamental laws of chemistry which are the law of conservation of mass and the law of definite proportions. The atomic theory states that a chemical reaction is simply a rearrangement

Chemical Reaction:- The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance. (b) Change of colour of substance

Introduction: Chemical equilibrium is when the concentrations of the reactants and products have reached a state where reactions occurring in one direction are at the same rate of reactions occurring in the opposite direction. This process‚ called dynamic equilibrium‚ is the main subject of Le Chatelier’s Principle. Le Chatelier pointed out that if a system at equilibrium is subjected to a stress that momentarily causes the system to be not in equilibrium‚ a spontaneous change will occur to

Energy‚ often in the state of heat‚ is involved in chemical reactions and phases changes. Changes in energy‚ can translate in temperature differentiations. In such a case‚ energy is transferred as heat. The quantity of heat exerted in a reaction referred to as (joules) can be identified through the following equation: Heat Exerted= (Mass of Sample) x (Specific Heat) x (Change in Temperature) q=msΔT Within a calorimeter is where the reactions within this lab take place. A calorimeter allows the

Thomas Newberg Chemical Weapons Convention Historically chemical weapons are rarely seen in combat but when they are they are used to great effect‚ killing thousands and injuring many more. Chemical weapons were first used in combat in May 1915 when the Germans released chlorine gas against the French in the Battle of Ypres. Over the course of WWI new chemical agents were developed including cyanide‚ phosgene and mustard gas. The Geneva Protocol of 1925 condemned chemical weapons but states that
