The element Sc has to be named along with their Group number in periodic table has to be given and also whether it is a metal, nonmetal, or metalloid has to be identified. Concept Introduction: Metals are elements that have characteristic properties of thermal conductivity, luster, electrical conductivity, and malleability. Except mercury, the physical state of all other metals is solids. They have very high melting points and high density. Nonmetals are elements that are characterized by the absence of properties like thermal conductivity, luster, electrical conductivity, and malleability. Mostly nonmetals are gases. Only bromine is present as liquid in room temperature. The density of nonmetals is low and they have lower melting points than metals. Metalloids are elements that possess both metallic and nonmetallic properties. Element present in the periodic table are represented by a unique name and a chemical symbol. The chemical symbol of an element is made up of one or two letters. For most of the elements, the chemical symbol is the first two letters of the element name. Some of the elements symbol are taken from Latin, Greek, or German names also.

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? (2 pts) Offspring Height (Inches) 75 67.5 60 52.5 y = 0.9264x + 4.8519 55 60 65 MidParent Height (Inches) 70 75 12pt v V Paragraph B IUA > AT2 v V

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.
