Answer:
For carbon the most important forms of hybridization are the sp2- and sp3- hybridization. Besides these structures there are more possiblities to mix dif- ferent molecular orbitals to a hybrid orbital. An important one is the sp- hybridization, where one s- and one p-orbital are mixed together.
Gases are less dense and the molecules are farther apart which means that it can be compressed
Number 1 is 4.875 Number 2 is 3.47 repeating
Boiling point is the temperature at which a liquid boils and turns to a gas.
