True, buoyancy is the force a fluid exerts upon an object on its surface.
Answer:
Cryogenic distillation
Explanation:
Cryogenic Distillation is the process in which Nitrogen and Oxygen are separated from air. Thus in cryogenic distillations the components having very low boiling points are distilled selectively at low temperatures. This method produces products of high purity but also it is quite energy intensive.
Answer: <em><u>125 g</u></em>
Explanation:
Mass = Volume × Density
⇒ Mass of the water = 125 mL × 1.0 g/mL
= 125 g
The carbon atom is uniquely suited to building large molecules primarily because of its valence electron count of 4 - which means it can bound up to 4 atoms (single bonds) simultaneously. Also, it has a relatively low molecular weight and the best part is that it forms covalent
bonds (stable, high
energy bonds) with other, non-metallic atoms.
