In metallic bonding, atoms form a crystal structure with 8 – 12 neighboring atoms. Every metal atom can bond equally well with all other atoms of the same metal, so if some of the atoms are shifted, they can usually bond immediately with their new neighbors. What property of metals does this help to explain the most?

The concept of empiricism states that all rationally accepted knowledge is determined from experience. francis bacon was one of the first scientists to promote this theory. what was it’s impact on society?

Based on its chemical properties, identify the position of each chemical family on the periodic table.

Modern pennies are composed of zinc coated with copper. a student determines the mass of a penny to be 2.482 g and then makes several scratches in the copper coaling (to expose the underlying zinc). the student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the hcl (the copper remains undissolved): zn(s) + 2 hcl(aq) → h2(g) + zncl(aq)the student collects the hydrogen produced over water at 25 °c. the collected gas occupies a volume of 0.899 l at a total pressure of 79 j mmhg. calculate the percent zinc (by mass) in the penny. (assume that all the zn in the penny dissolves.)
