What is the average kinetic energy of 1 mole of a gas that is at 100 degrees Celsius?

Answers

Answer 1

Answer: To simplify our solutions, we have to assume that the gas we are referring is ideal. The kinetic energy of of ideal gas is a funtion of moles and temperature only.
KE = (3/2)(nRT)
= (3/2)(1mol)(8.314J/molK)(100+273.15) = 4204.6J

The fermentation of C6H12O6 will produce CO2 and 1. C3H5(OH)3 2. C2H5OH 3. Ca(OH)2 4. Cr(OH)3

Answers

Answer is "2 - C₂H₅OH".

Fermentation is a process which is used to produce energy from sugars (glucose, sucrose and fructose) in the absence of oxygen.

Fermentation with the glucose releases energy by producing carbon dioxide (CO₂) and ethanol (C₂H₅OH) as its byproducts.
The reaction is
C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂ + energy

A beaker contains three solids: flour, sugar, and baking soda. Whichdescribes the contents of the beaker? *

Answers

Answer: It is a Heterogeneous mixture.

Final answer:

The beaker contains a mixture of three solids, namely flour, sugar, and baking soda. These components retain their properties in the mixture and are not chemically combined.

Explanation:

The contents of the beaker can be described as a mixture. A mixture is a combination of two or more substances that are not chemically combined. In this case, the beaker contains flour, sugar, and baking soda. These are solid substances that maintain their own properties in the mixture. They're simply combined in the same space (the beaker), but they are not interacting on a molecular level to form a new substance.
