How does the volume of gas particles compare to the volume of the space between gas particles?

Chemistry
1 answer:
Ugo [173]3 years ago
3 0
Gas particles are small and the total volume occupied by gas molecules is negligible relative to the total volume of their container. ... The average kinetic energy of gas particles is proportional to the absolute temperature of the gas, and all gases at the same temperature have the same average kinetic energy

Explain the optical activity of malic acid? <br>Draw a pair of stereoisomers of malic acid.​
mr_godi [17]

Under standard temperature and pressure, the optical activity of malic acid changes in the following ways:

  1. Wavelength of light
  2. Magnitude
  3. Temperature
  4. Concentration of solvent.

<h3>What is an optical activity?</h3>

An optical activity is also referred to as optical rotation and it can be defined as the ability of a substance or chemical compound to rotate the plane of polarization of a beam of plane-polarized light that passes through it.

<h3>What is malic acid?</h3>

Malic acid refers to an organic compound (dicarboxylic acid) that is typically made by all living organisms and its molecular formula is C_4H_6O_5. Malic acid is considered to be one of the most satisfactory substances to be used when studying optical activity because of its chemical properties such as having single asymmetric carbon atoms.

Under standard temperature and pressure, the optical activity of malic acid changes in the following ways:

  1. Wavelength of light
  2. Magnitude
  3. Temperature
  4. Concentration of solvent.

<h3>The stereoisomeric forms of malic acid.​</h3>

In Science, there are two (2) stereoisomeric forms of malic acid and these include:

  • L-enantiomers
  • D-enantiomers

Answer:

What substance changed physically under all three condition? Copper Wire

What substance changed chemically under all three condition? Steel Wool

What evidence indicates a chemical reaction is occurring? New gases are produced; A phase change has occurred; A color change

Select the three answers that are examples of a chemical reaction. The mixing of an acid and base shows an increase in temperature; after baking bread there is a new odor or smell; when hair is bleached it changes to a lighter color

Which data supports this inference? Baking soda dissolving; A gas formed, creating bubbles

Which experiment best shows evidence of energy being released in a chemical reaction? Heat and light are given off when paper is burned

Which experiment likely resulted in the formation of a precipitate? Two solutions are mixed together and a yellow solid forms

The BEST evidence for a chemical reaction is the formation of a new substance.

Explanation:

2. When heat and light are being given off, energy is being released. Paper burning is a chemical reaction b/c when paper is burnt, it is a new substance and the act can't be undone.

3. When a yellow solid forms, that solid is the participate.

4. You will for sure have a chemical reaction if a new substance is created.

5. Copper wire changed physically b/c the copper wire can be returned to its original condition in all of these situations and no new substance was formed. Steel Wool changed chemically b/c it can't be returned to its original state under any condition and new substances were formed every time.

6. New substances formed indicate a chemical reaction. A color change also is an indication of a chemical reaction.

7. When a substance can't be turned into its original position or a new substance is produced, a chemical reaction occurred.
