How do you determine the molar mass of Al2(CO3)2 using the periodic table? Group of answer choices

Add up the mass of aluminum, carbon and oxygen

Add up the mass of aluminum x 2, carbon, and oxygen x 3

Add up the mass of aluminum x 2, carbon x 2 and oxygen x 3

Add up the mass of aluminum x 2, carbon x 2 and oxygen x 6

In which phase(s) do the molecules take the shape of the container?

Draw the skeletal structures of two different molecules that are each made of 5 carbon atoms and 12 hydrogen atoms.

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.
