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

According to Doweiko (1999)‚ “A drug is essentially a foreign chemical that is introduced into the individual’s body to bring about a specific desired response. There are many forms of drugs and how these drugs are administered in the body determines the kind of result that will take place. The Central Nervous System‚ (CNS) plays a major role in how these drugs will affect the body because the chemicals carry out

mixtures were collected and tested by different individuals in the lab in order to find the eutectic point of biphenyl. Unknown substances were then tested using the mixture melting point method in order to determine their identities. INTRODUCTION The melting point of a solid is the temperature where the substance changes from a solid to a liquid state. Using known substances and determining their melting points is a way to establish the purity of and to identify a sample. This lab demonstrates the
