False
Explanation:
The geologic time scale which simplifies earth's long history is broad division of deep time. It consists of a large and small divisions.
- The geologic time scale is divided into large broad categories; called eons, eras, period and epoch.
- The scale is merges absolute dating of events that has happened in geologic past and their relative ages.
- Broad categories on the scale are further simplified into smaller units.
- Relative age puts events in the order of their appearance using a couple of geologic principles.

Molar mass of C: 12.011 g/mol
The equation says C20, which means there are 20 carbon atoms in each molecule of Vitamin A. So, we multiply 12.011 by 20 to get 240.22 g/mol carbon.
Molar mass of H: 1.0079 g/mol
The equation says C30, which means there are 30 hydrogen atoms in each molecule of Vitamin A. So, we multiply 1.0079 by 30 to get 30.237 g/mol hydrogen.
Molar mass of O: 15.999 g/mol
The equation says O without a number, which means there is only one oxygen atom in each molecule of Vitamin A. So, we leave O at 15.999 g/mol.
Then, just add it up:
240.22 g/mol C + 30.237 g/mol H + 15.999 g/mol O = 286.456 g/mol C20H30O
So, the molar mass of Vitamin A, C20H30O, is approximately 286.5 g/mol.
Conservation, because you are conserving natural resources(water) and reusing aluminum cans which help the environment. Hope this helps!
I picture is unclear but
I can help if u send me it
