Answer:
Sleep homeostasis denotes a basic principle of sleep regulation. A sleep deficit elicits a compensatory increase in the intensity and duration of sleep, while excessive sleep reduces sleep propensity

Explanation:
Balancing:
2Au₂S₃ + 6H₂ → 4Au + 6H₂S
Compound B will be propene as a result of an elimination reaction involving potassium tert-butoxide and an alkyl halide. In proton NMR, alkenes exhibit signals in the 5–6 ppm range.
<h3>What are Elimination Reactions?</h3>
Elimination reactions are one sort of reaction that are mostly utilized to convert saturated compounds (organic molecules that contain single carbon-carbon bonds) to unsaturated compounds (compounds that feature double or triple carbon-carbon bonds). Additionally, it plays a significant role in the production of alkenes.
The elimination response is composed of the following three major events:
- Proton exclusion.
- The synthesis of a C-C pi bond.
- As a result, the relationship between the departing group's members has grown increasingly distant.

Answer:
1.51 x 10²⁴molecules
Explanation:
Given parameters:
Number of moles of NaCl = 2.5moles
Unknown:
Number of molecules = ?
Solution:
The number of molecules that can be found in a given mole is given as the Avogadro's constant;
1 mole of substance = 6.02 x 10²³ molecules
2.5 mole of NaCl = 2.5 x 6.02 x 10²³ molecules
= 1.51 x 10²⁴molecules
