When copper (Cu) and oxygen (O) combine, two different compounds are formed. The first compound contains 88.8% copper by mass, and the second compound contains 79.9% copper by mass. (Note: Assume a 100-gram sample of each compound.) (a) Show that Cu and O combine with each other in conformity with the law of multiple proportions. The small whole number ratio of the mass of Cu per gram of O in the first compound to the mass of Cu per gram of O in the second compound equals :1. This ratio indicates that Cu and O ---Select--- combine do not combine with each other in conformity with the law of multiple proportions. (b) Determine the empirical formulas of the compounds. compound 1: compound 2:

Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
