? b) Carbon (II) oxide reacted with oxygen to form carbon (IV) oxide in a sealed tube.
Write a balanced equation for the reaction.
If 40 cm' of the carbon (II)oxide were mixed with 30 cm' of oxygen,
I. calculate the volume of carbon (IV) oxide produced?
which reactant is in excess and by how much?
III. what was the total volume of the gaseous mixture at the end of the
reaction?

II.

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
