    The Aim of the experiment: In this experiment I will investigate the relationship between the concentration of the hydrochloric acid and the rate of a reaction. To find this out I will react different concentration of hydrochloric acid and magnesium‚ from there I will monitor the gas (hydrogen) produced and analyse the results. Prediction: I predict the higher the molarity of the hydrochloric acid the faster the rate of reaction therefore the quicker the gas will be produced in the specific

    Crater Design Experiment Aim: To see how the height in which the ball is dropped from affects the depth of the crater. Hypothesis: I predict that as the height in which the ball is dropped from increases‚ so does the depth of the crater (the data will be directly proportional). The scientific knowledge which supports this is that the golf ball has a gravitational potential energy which increases as the ball is dropped from higher heights. When the height increases the ball gains more gravitational

    Monica Perez Experiment 8: Acetylsalicylic Acid Experiment 01/25/2013 CHM Lab- 2211 Sec 0016 Instructor: Jennifer Reed Introduction: Commonly used as Aspirin‚ acetylsalicylic acid is an analgesic (pain reliever)‚ which is one of the products of the esterification reaction between salicylic acid and acetic anhydride. This esterification occurs since the hydroxyl group from the salicylic acid reacts with acetic anhydride to form an ester. In this experiment‚ we will be able to recreate

    Lung Volume Activity The graph below is called a spirograph. It represents the amount of air that moves into and out of the lungs with each breath‚ as measured by a device called a spirometer. (The terms that are used to describe the features of a spirograph are explained below.) • Tidal volume is the volume of air that is inhaled and exhaled in a normal breathing movement when the body is at rest. • Inspiratory reserve volume is the additional volume of air that can be taken into the lungs

    purpose of these experiments was to probe and manipulate the activity of the enzyme peroxidase by varying temperature‚ pH‚ the amount of enzyme compared to the substrate and the effect of hydroxylamine. Peroxidase activity is expressed when the potato extract is subjected to stresses such as low temperature (El-hilali et al.‚ 2012). The most eye catching factors that we tested for their impact on enzyme activity involved change in pH‚ temperature‚ boiling extract‚ and the effects of probing the active

    ABSTRACT The Stroop experiment focuses on the interference of a person’s reaction time on a given task. Certain tasks can be performed with more accuracy due to the fact that our brain becomes conditioned to react automatically after exposure of the stimuli. In this particular experiment‚ eight-teen college students underwent the Stroop experiment in individualized laboratory rooms. Four students were male and fourteen were females. The experiment helped us examine the horse race model
