Lord Kelvin, were he alive today, would be considered a Thermochemist. Thermochemistry is interested in the role of heat in chemical reactions. This includes the role of heat both as a biproduct of chemical reactions and a facilitator.
Kelvin's description of absolute zero is an important concept in thermochemistry. At absolute zero, there is no movement of molecules, and no energy available facilitate chemical reactions.
Noble gases are very unreactive, so you're not going to see them anywhere that reactivity is important. In fact, one of the main places they're used is in environments where reactions need to be stopped - to replace air in a reaction environment, for example.
To make steel, batteries, and Xerox machines, you wouldn't want something unreactive. Fluorescent light bulbs ("neon bulbs"), on the other hand, fit the bill nicely.
Answer:
V = 3.75 cm³
Explanation:
Density = Mass / Volume
Step 1: Define variables
D = 8.00 g/cm³
M = 30.0 g
V = unknown
Step 2: Substitute and Evaluate for V
8.00 g/cm³ = 30 g/ V
V = 15/4 cm³
V = 3.75 cm³

Explanation:
Calculate the mass of NaOH required to prepare a 0.343 M solution dissolved in 2500 mL of water. 0.343 M = x mol / 2.5 L = 0.86 mol 0.86.
Structures such as the ribosome, endoplasmic reticulum, and mitochondria cannot be viewed by the 10x objective lens. These organelles are too small to be viewed with low magnification and require over 2000x magnification. At low magnification structures such as the cell wall, vacuoles, and cytoplasm can be viewed.
