When the concentration of a system is changed:

Chemistry
1 answer:
KIM [24]3 years ago
7 0

Answer:

The concentrations change to maintain the original value of K.

Explanation:

When the concentration of a system is changed, the system adjusts in order to preserve the original value of the equilibrium constant K.

  • The equilibrium constant is a constant at a given temperature and it is temperature dependent in nature.

According to Le Chatelier's principle;

  • If any conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change.
  • Stress due to any of pressure, temperature and concentration changes displaces the equilibrium.

Answer:

(1) Carbon + (4) Chlorine = Carbon tetrachloride (CCl4)

Explanation:

Carbon Tetrachloride is a clear, colorless, volatile and very stable chlorinated hydrocarbon. Carbon Tetrachloride is used as a solvent for oils and fats, as a refrigerant and as a dry-cleaning agent. Inhalation of its vapors can depress central nervous system activity and cause degeneration of the liver and kidneys. Carbon Tetrachloride is reasonably anticipated to be a human carcinogen based on evidence of carcinogenicity in experimental animals.

24. Element X has five valence electrons, element Y has one valence electron, and element Z has one valence electron. Which two
natka813 [3]
Elements Y and elements Z would have similar properties due to the fact that they both posses the same number of valence electrons. They both have a single valence electron that determines the corresponding elements bonding properties and the fact that it can either donate 1 valence electron to produce an ion that would be attracted to another atom, that is also an ion. Assuming that these elements are group 1 elements, they do not undergo in covalent bonding.

Is it true that an atom has 3 subatomic particles with a negative nucleus and the neutrons outside the the nucleus
Nostrana [21]

Answer: atoms do have 3 subatomic particles but the nucleus is positive and the nucleus consists of protons and neutrons. Its positive because neutrons have no charge and protons have a positive charge. There are only electrons on the shells so no neutrons or protons on the shells
