Analytical Balance PrincipleOne of the essential laboratory procedures in analytical chemistry is measuring the mass of an object. An analytical balance is used to determine a mass with high accuracy. Its maximum capacity ranges from 1 g to a few kilograms with a precision of at least 1 part in 105. Different apparatus techniques are.

Chemistry Lab Kinetics of a Reaction Theory: for this lab we will be using concentrations and the temperature of a Reaction to see how it affects the reaction rate.Rate law for a reaction is a mathematical expression that relates the reaction rate to the concentration of reactants.The total rate law is determined by measuring rate,evaluating.
Chemistry Coursework – “the Dissappearing Cross” Chemistry Coursework – “the Dissappearing Cross” CHEMISTRY COURSEWORK- “THE DISSAPPEARING CROSS” PLANNING Background Information: During a chemical reaction the reacting particles must collide with each other, however, collision alone does not guarantee that the reaction will start. Reaction will only occur if the colliding particles have sufficient combined energy.

Chemical Equilibrium Essay title: Chemical Equilibrium CHEMICAL EQUILIBRIUM Reversible reactions and dynamic equilibrium Ammonia (NH3) is an important industrial chemical that is used in the manufacture of fertilisers. It is manufactured by reacting hydrogen with nitrogen. The reaction is said to be reversible and the conversion of reactants to products is never complete. N2 +.
Chemistry Essay title: Chemistry Plan This investigation is about rates of reaction and what affects them. In this case I am going to look at hydrochloric acid and sodium thiosulphate which is a precipitation reaction. They react as in the equations below: Sodium thiosulphate + hydrochloric acid -> sodium chloride + sulphur + sulphur dioxide.
