Problem 19E

Problem 19E

Classification and Properties of Matter (Sections) Label each of the following as either a physical process or a chemical process: (a) rusting of a metal can, (b) boiling a cup of water, (c) pulverizing an aspirin, (d) digesting a candy bar, (e) exploding of nitroglycerin.

Step-by-Step Solution:
Step 1 of 3

Isotopes Isotopes vary in the number of neutrons and therefore have different masses but remain the same element Isotopes are named by their masses, for example carbon 14 has one more neutron than carbon 13 The mass of an element on the periodic table is an average of all of its isotopes and their concentrations in nature, this is called the average molar mass Average molar mass = Σ (mass of each isotope) x (% abundance/ 100) The periodic table Each column has similar properties and is called a group (or family) Each row of the periodic table is called a period The table has 18 groups and 7 periods Metals:  on the left side of the periodic table  conduct electricity  malleable and ductile  have luster, mostly solid Metalloids:  located on the zig-zag lin
