- Researchers isolated an unknown substance, X, from rabbit muscle. They determined its structure from the following observations and experiments. (a) Qualitative analysis showed that X was composed entirely of C, H, and O. A weighed sample of X was completely oxidized, and the H2O and CO2 produced were measured. This quantitative analysis revealed that X contained 40.00% C, 6.71% H, and 53.29% O by weight. (b) The molecular mass of X, as determined by mass spectrometry, was 90.00 atomic mass units (u). (c) Infrared spectroscopy showed that X contained one double bond. (d) X dissolved readily in water, and the solution demonstrated optical activity when tested in a polarimeter. (e) The aqueous solution of X is acidic. What is the empirical formula of X?In the preparation of a standard stock solution for protein analysis, 50 mg of bovine serum albumin (BSA) was dissolved in deionized distilled water to a final volume of 10 mL. What is the weight of BSA in 0.60 mL stock solution?Jack and Jill are curious about the factors that affect plant growth. They perform several experiments using pea plants (a) The leaves of the pea plants that received too much water turned yellow. (b) Jill decided that 5 hours of indirect sunlight gave optimum growth. (c) Jack gave the pea plants a controlled amount of water each day. (d) Jill thinks that too little sunlight will affect plant growth. This part please (a) Identify one variable (other than water and sunlight) that could be tested. (b) Write a hypothesis using this variable. (c) Design an experiment to test this variable.
