In descriptive investigations, we still haven't formed any hypothesis yet so we seek information by asking question.
It's not repeatable because repeating the questions over and over again without any clue about what we want to seek is completely waste of time.
Hope this helps xox :)
Answer:
every method of removing heat from LED's should be considered. Conduction, convection, and radiation are the three means of heat transfer. Typically, LED's are encapsulated in a transparent resin, which is a poor thermal conductor. Nearly all heat produced is conducted through the back side of the chip. Heat is generated from the PN junction by electrical energy that was not converted to useful light, and conducted to outside ambiance through a long path, from junction to solder point, solder point to board, and board to the heat sink and then to the atmosphere. A typical LED side view and its thermal model are shown in the figures.

The molecular compound in the given statement is CH₆N₂.
<h3>What defines a molecular compound?</h3>
Chemical compositions of molecules that make up molecular compounds reflect the number of elements that are really bound together within the molecule. Due to the sides and angles of a atoms' links to one another, the complex has a certain structure.
<h3>Briefing:</h3>
Consider 140.22 g/mol of compound
Carbon = 140.22 * 51.38/100
Carbon = 72 gm = 1 mol
Hydrogen = 140.22 * 8.64/100
Hydrogen = 12 gm = 6 mol
Nitrogen = 140.22 * 39.97/100
Nitrogen = 56 gm = 2 mol
The molecular compound is CH₆N₂.

The complete question is -
A compound with molar mass 140.22g/mol is known to contain 51.38% carbon, 8.64% hydrogen and 39.97% nitrogen. Find the molecular of this compound.
If Salmon are raised in a fish farm then they will be healthier since they aren't being exposed to predators or disease.
I'm not fully sure if this is good enough since it seemed like your question had multiple choice but this is generally a testable hypothesis.
