Q1) The best description for molecule b in the diagram is adenosine diphosphate because there are only two phosphate groups. (b)
Q2) I would say b again, but I am not 100% sure. In the diagram, ATP seems to have given off a phosphate group and become ADP. The other answers are all not specified in the diagram, but rather inferences from what might be happening.
5 atoms is in 2CaCO3
Element: 1 atom
Compounds: 2+ atoms
Mass = 5 g
volume = 20 cm³
density = mass / volume
therefore:
D = m / V
D = 5 / 20
D = 0.25 g/cm³
Answer:
C. Ketone
Explanation:
According to the definition, the ketones are organic compounds which incorporate a carbonyl functional group, C=O. The carbon atom of this group has two remaining bonds that should be bonded to other carbon atoms. In this case the structure shows two ketone functional groups. Then the correct answer is C.
