Answer:
The White Dwarfs are very hot stars, which are small in size and relatively dim. They are found in the lower left of the H-R Diagram. The Main Sequence is a band of stars, which includes most of the stars, like our Sun. These are usually smaller stars, often dwarf stars.
Explanation:
Answer A: Connect a wire coil to an ammeter. Move a bar magnet into and out of the wire coil as you observe the ammeter.

</span><span>1) Water at 0.0060 atm and 0.01° C is at its triple point.
</span>
2) The triple point is the point in the phase diagram at which the three physical states coexist: gas, liquid and solid.
3) That means that water can freeze and boil at the same time. In fact they can happen any of the six changes of phase: freezing (liquid to solid), melting (solid to liquid), evaporation (liquid to gas), condensation (gas to liquid), sublimation (solid to gas), and deposition (gas to solid).
The phase diagram is unique for any substance, meaning that it is different for different substances: the normal boiling and melting points are different.
Answer:
From what I personally know, Acenaphthylene 75%. Empirical Formula (Hill Notation): C12H8. CAS Number: 208-96-8. Molecular Weight: 152.19. Beilstein: 774092. EC Number:
Explanation:
Acenaphthylene, a polycyclic aromatic hydrocarbon is an ortho- and peri-fused tricyclic hydrocarbon. The molecule resembles naphthalene with positions 1 and 8 connected by a -CH=CH- unit. It is a yellow solid. Unlike many polycyclic aromatic hydrocarbons, it has no fluorescence. Acenaphthylene/Formula is C12H8.
I'm not sure if this will help you but this is what I know so I hope it does :)
