Answer:

It has to do with increasing the entropy of the universe.

Explanation:

The modern definition of entropy is that it is the extent to which a system is able to disperse its energy. Energy (such as heat!) likes to spread itself out, so that as many states as possible are occupied with the least amount of energy.

How can you distinguish between a physical change and a chemical change?

AleksAgata [21]

Answer:

Physical Change

When a substance undergoes a physical change, its composition remains the same despite its molecules being rearranged.
Physical change is a temporary change.
A Physical change affects only physical properties i.e. shape, size, etc.
A physical change involves very little to no absorption of energy.
Some examples of physical change are freezing of water, melting of wax, boiling of water, etc. .
In a physical change, no new substance is formed.
Physical change is easily reversible i.e original substance can be recovered.

Chemical Change

When a substance undergoes a chemical change, its molecular composition is changed entirely. Thus, chemical changes involve the formation of new substances.
.A chemical change is a permanent change.
Chemical change both physical and chemical properties of the substance including its composition
During a chemical reaction, absorption and evolution of energy take place.
A few examples of chemical change are digestion of food, burning of coal, rusting, etc.
A chemical change is always accompanied by one or more new substance(s).
Chemical changes are irreversible i.e. original substance cannot be recovered.

A solution of hcl in water conducts electricity, but a solution of hcl in chloroform, chcl3, does not. what does this observatio

PSYCHO15rus [73]

Hydrochloric acid (HCl) dissociate on positive ions or cations of hydogen (H⁺) and negative ions or anions of chlorine (Cl⁻). When there is free cations and ions, water solution can conduct electricity. Chloroform do not dissociate on ions in water, because that is not polar molecule, so chloroform is in molecular form in solution.

Which ionic compound is water soluble? CuS NH4 NO3 SrSO4 ZnF

katovenus [111]

Just use a solubility chart! Find the cation on the far left and the anion on the top and find where they connect. If it says "s," it is not soluble. If it says "aq," it is soluble. Here, ZnF (Zinc Fluoride) is soluble. Hope that helps! :)

P.S. Not all of the compounds above are on this particular chart. In future problems, just google "solubility chart" until you find one with all of the compounds you need to look at.

The primary mechanism for converting atmospheric carbon into usable forms for life on earth is achieved by

Elan Coil [88]

The primary mechanism for converting atmospheric carbon into usable forms for life on earth is achieved by photonsynthesis. It is a process where plants convert carbon dioxide into forms that can be used by living organisms which is oxygen. Oxygen is a very essential product of photosynthesis which is being used by living organisms to survive.
