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

I. Introduction There are two types of chemical reaction that occur one goes only in one direction and the other one is reversible. A reversible reaction is when a products starts to form the backward reaction starts where the products turns back to reactant molecules. When the rate of forward and backward reaction is already equal and the concentrations of the reactants and products no longer change with time we can say that chemical equilibrium is already achieved. A reaction is said to be at
