Experiment: reactions of alkanes, alkenes, and cycloalkenes purpose: to investigate the physical properties, shake the mixture hold, with forceps, a piece of moistened blue litmus paper and lower by comparing the observations you made for your unknowns with that of the. A dynamic state where two opposing forces are in balance, where two opposite events are occurring at equal rates the building process is equal in rate to the tearing-down process.

Students conducted an experiment to determine the effect of light intensity on the rate of photosynthesis they punched 40 leaf disks from spinach leaves and used a syringe partially filled with water to pull the gases from the leaf disks so that all leaf disks sunk to the bottom of the syringe. 2 two of the liquids, n-pentane and 1-butanol, had nearly the same molecular weights, but significantly different t values explain the differences in t values of these substances, based on their intermolecular forces 3 which of the alkanes studied has the stronger intermolecular forces of attraction explain using the results of procedure 1 4.

An experiment comparing the level of skeletomuscular activities produced by shake weights and traditional free weights (456 words, 7 pages) introductionelectromyography, also known as emg, is a visual representation of muscle activity used throughout healthcare and medical research settings. 13after you have completed all the activities and experiments have your students work in groups to define what a liquid is, what a solid is, and what a gas is ahave students use large pieces of paper to write and illustrate their definitions of these three states of matter. To carry the comparison to an unrealistic level, an experiment was performed to compare yields obtained from inocula homogenized for 150 s and 600 s (table 4b) only the biomass harvested after 7 d revealed a highly significant difference between the yields of the 150 s (102 g) and 600 s treatment (68 g.
