of Fermentation How does gelatin affect the process of fermentation? The experimenters hypothesized that the more gelatin that was added into the mixtures of yeast and water‚ the more the mixtures will ferment. The experimenter’s hypothesis was not determined correct or incorrect due to the inconclusive results of the experiment. Throughout the experiment‚ none of the balloons grew from fermentation. The results of the labs were meant to measure the CO₂ released into the air by fermentation. The

In this lab we tested to see if the amount of sunlight exposed to the basil seed‚ would affect the growth. The null hypothesis for this experiment was that there would be no statistical difference between the green‚ yellow‚ and red basil seeds’ growth. Three alternate hypotheses are: If we expose the green seed to 48 hours of sunlight and the yellow seed to 24 hours of sunlight‚ then the green seed with grow more than the yellow. The opposite of this hypothesis would alternate 2. Another alternate

and therefore the crude solid must be purified. This purified product is what is later put into the analgesic. In this experiment‚ the procedures that are important are vacuum filtration and recrystallization which are both used to obtain the Acetaminophen product. When collecting products‚ it is important to know how much product is left and what is lost through the experiment. To do this‚ the balanced equation will be looked at and then the theoretical yield will be calculated. In order to calculate

Appendix Abstract: This experiment is intended to introduce the basic concepts of the operational amplifiers and to help us better understand the relationship between the resistances and the amplifier gain. The main experiment focused on op-amps of which we have two types‚ inverting and non-inverting. With the inverting op-amps there is no current

EXPERIMENT 8 BOILING POINT n-Butyl Alcohol n-Butyl Alcohol‚ a four carbon straight chain alcohol‚ is a volatile‚ clear liquid with a strong alcoholic odor; miscible with water. It is flammable strongly with a luminous flame. Formula: C4H9OH Boiling point: 118 ºC Melting point: -89 ºC Tert-Butyl Alcohol Tert-Butyl Alcohol or “2-methyl-2-propanol” is the simplest tertiary alcohol. It is one of the four isomers of butanol. Tert-Butanol is a clear liquid (or a colorless solid‚ depending on

BALANCE LAB Introduction The purpose of this lab is to become familiar with how to use the ChemLab program for determining mass using both the centigram balance and the electronic balance. Using the centigram balance‚ the mass‚ in grams‚ of a copper slug will be determined by both direct weighing and weighing by difference techniques. Using an electronic balance‚ the wight of a copper slug will be determined by also utilizing direct weighing and weighing by difference. Average mass of a
