What chemical substance is this atomic structure represent?

From the standpoint of entropy, consider the following processes: water boiling, mixing cola and root beer sodas, and assembling

Triss [41]

Answer:

b) Water boiling and mixing cola and root beer sodas are favorable processes, but assembling a house of cards is not.

Explanation:

Entropy, a measure of a system's thermal energy per unit of temperature that cannot be used to do work. Work, is obtained from directed motion of molecules, it follows the the amount of entropy is a measure of the molecular randomness, or disorder, of the system. As such increased entropy increases randomness hence water boiling and mixing cola and root beer sodas are favorable processes, but assembling a house of cards which requires a great deal of effort is not.

A 1300 mL sample of gas with a molar mass of 71.0 g/mol at STP has what density?

Blizzard [7]

Answer:

0.055g/mL

Explanation:

Data obtained from the question include:

Molar Mass of the gass sample = 71g/mol

Volume of the gas sample = 1300 mL

Density =?

The density of a substance is simply mass per unit volume. It is represented mathematically as:

Density = Mass /volume.

With the above equation, we can easily obtain the density of sample of gas as illustrated below:

Density = 71g / 1300 mL

Density = 0.055g/mL

Therefore, the density of the gas sample is 0.055g/mL

Sediments are almost always deposited in flat layers. Does it appear that forces in the Earth affected the rock layers in this r

kirill115 [55]

Answer:

Explanation: Sediments or sedimentary rocks are formed from pre-existing rocks broken through the agents of denudation such as air, ice, water flow which carries the particles and deposits it, the accumulation of one layer on the others is called DEPOSITION. As the deposits keeps building, LITHIFICATION occurs which involves overburden pressure acting on the sediments in layers.

Note that during deposition oldest layers are below, while the younger layers are above
