QUESTION 1. Isotopes of a chemical element have all the same chemical characteristics. However, once the isotopes form chemical bonds, the chemical bonds of heavier isotopes are stronger than those of lighter isotopes. In addition, heavier isotopes have different physicochemical properties. As a consequence, mole- cules made up of lighter isotopes have lower melting and boiling points than molecules with heavier isotopes. These differences can be used to determine the source of protein in human diet or whether food labels regarding origin, rearing conditions of animals, or purity of content (e.g., no sugar added to maple syrup) are correct. Use the provided information and determine whether the beef used in ham- burgers of fast food restaurants comes from corn-fed or grass-fed cattle. Ex- plain how you solved the problem.

Diane, Timothy and Ira were having a discussion about isotopes and the tendency to react. Which do you suggest offers the best explanation? Diane felt that isotopes would react the same as the atoms of the same element since they had the same number of valence electrons. Timothy suggested that they would react the same since the isotope and the atom of the same element would have the same number of total electrons. Ira said that the isotopes would react different since the number of neutrons would vary and therefore the atomic mass of the isotopes versus the atom of the same element would be different.
1. Whenever chemists observed atoms reacting with each other, they noticed that the sum of their group numbers usually equaled eight, or multiples of 8 (16, 24, 32, 40, etc.). This is called The Rule of Eight. How does this Rule of Eight work in understanding chemical formulas?2. Chemical formulas are written to show how many atoms of each element are bonded together to make a molecule of a substance. For example, C6H12O6 is the chemical formula for one molecule of sugar.3. Look at water: H20. By looking at this formula, you know that it takes _____ hydrogen atom(s) to bond with _______ oxygen atom(s).4. Now, add the group numbers. Hydrogen has a group # of 1A. Oxygen has a group number of 6A. Two hydrogens (1 + 1) and one oxygen (6) equals a total of 8. The Rule of Eight!5. Try another simple one, table salt (sodium chloride, NaCl). The formula tells you that it takes ______ sodium atom(s) to bond to ______ chlorine atom(s). Add the group numbers: The group # for…
