Boiling Point Electrical conductivity in aqueous solution Solubility in H2O (grams of solid in 100 grams H2O)
A Low, 65o C Poor 3.0
B High 1600o C Good 36.0

Carl and Sally designed an experiment to compare and contrast the properties of covalent and ionic compounds. After designing their experiment, Carl and Sally tabulated the data in the table seen here. A represents the covalent compound; B the ionic compound. Based on their data, it is apparent that Carl and Sally probably used all of the lab equipment EXCEPT a/an

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
