In the chemical reaction , C H 4 + 2 O 2 → C O 2 + 2 H 2 O , the number of moles of C O 2 that is formed has to be chosen from the given option, at the same time of 2.0 m o l e s of H 2 O being formed Concept Introduction: The coefficients that are present in a balanced chemical equation is like subscripts in the chemical formula. These coefficients can be interpreted in two levels. One is a microscopic level and another is macroscopic level. Microscopic level: The coefficients that are present in a balanced chemical equation gives numerical relationship between the formula units consumed or produced when a chemical reaction takes place. Macroscopic level: In a balanced chemical equation, the coefficients give information about the fixed molar ratios among the substance that is consumed or produced when a chemical reaction takes place.

Dr. Mendel asked his BIOL 260 class what their height was and what their parent's heights were. He plotted that data in the graph below to determine if height was a heritable trait. A. Is height a heritable trait? If yes, what is the heritability value? (2 pts) B. If the phenotypic variation is 30, what is the variation due to additive alleles?

Experiment: Each team will be provided with 5g of a mixture of acetanilide and salicylic acid. You will divide it into three 1.5 g portions in separate 125 mL Erlenmeyer flasks savıng some for melting point analysis. Dissolve the mixture in each flask in ~60mL of DI water by heating to boiling on a hotplate. Take the flasks off the hotplate once you have a clear solution and let them stand on the bench top for 5 mins and then allow them to cool as described below. Sample A-Let the first sample cool slowly to room temperature by letting it stand on your lab bench, with occasional stirring to promote crystallization. Sample B-Cool the second sample 1n a tap-water bath to 10-15 °C Sample C-Cool the third sample in an ice-bath to 0-2 °C Results: weight after recrystalization and melting point temp. A=0.624g,102-115° B=0.765g, 80-105° C=1.135g, 77-108 What is the percent yield of A,B, and C.
