3. a gas chro gram of the organic compounds of a sample of beer using a column that separates compounds on the basis of their relative boiling points several provides a glc trace with believed to be ethyl acetate and ethyl butyrate respectively peaks. two of the smaller peaks with retention times of 9.56 min. and 16,23 min, are a. from the above information, which compoanent of the sample, chyl actlate or dhyl betystn elutes faster? b. what are the reported boiling points of these two substances? what additional glc experiments you will do to confirm the retention times of these two substances? ( you are provided with samples of ethyl acetate and ethyl butyrate). c. how will you calculate their relative percentages given that area of ethyl acetate is 113 mm'and the area of ethyl butyrate is 65mm2 d.

What happens to the average kinetic energy of a gas when the particles of the gas collide against each other at a constant temperature and volume? explain your answer.

For a family dinner, jose’s mom baked a loaf of bread. during the meal, his grandmother commented, “this bread is so dense! ” what do you think his grandmother meant by the word dense? you have some ideas regarding density already, but this experiment will enrich your understanding of the relationship between mass, volume and the density of objects. when making measurements in this experiment we will be using si units, the international system of units. the purpose of using si units is to have the ability to communicate and compare data results with other experiments without having to make conversions. measurement symbol si unit length m meter mass kg kilogram volume l liters density kg/l kilograms per liter any calculations that are performed during this experiment will ultimately be reported in scientific notation. recall that scientific notation is extremely important when we have data that is extremely small or large. scientists rely on a standard form of communication to quickly make hypotheses and judgements based on data. what is the density of block a? a0kg/l what is the density of block b? a1kg/l what is the density of block c? a2kg/l what is the density of block d? a3kg/l what is the density of block e? a4kg/l which block is the densest? a5

If you are told to get 100 ml of stock solution to use to prepare smaller size sample for an experiment, which piece of glassware would you use?
