An amorphous solid is the result of <span>atoms or molecules that do not have long range.
</span>Long range order does not exist in amorphous solids and liquids. Amorphous means “without form or structure". in amorphous solid atoms and molecules are not organized in a definite lattice pattern. For example plastic, gel or glass.

Answer :  The correct option is, atoms or molecules that are closely spaced but are free to move around and past each other.

Explanation :

Amorphous Solids : It is a type of solids where the constituent particles of the matter are arranged in the random manner. That means there is no proper arrangement of atoms in solid lattice but the atoms or molecules are closely spaced that means they can move freely from one place to another. They do not have long range.

The examples of amorphous solid are, plastics, glass, rubber, metallic glass, polymers, gel, fused silica, pitch tar, thin film lubricants, wax.

Crystalline Solids : It is a type of solids where the constituent particles of the matter are arranged in the specific manner. That means there is a proper arrangement of atoms in solid lattice. They do not have space between the molecules or atoms and they can not move freely from one place to another.

The examples of crystalline solids are, quartz, calcite, sugar, mica, diamonds, snowflakes, rock, calcium fluoride, silicon dioxide, alum.

Hence, an amorphous solid is the result of atoms or molecules that are closely spaced but are free to move around and past each other.

What is the oxidation state of each element in the compound CaSO4? Include + or - in your answers as appropriate.
BartSMP [9]

Answer:- Ca = +2, S = +6 and O = -2

Solution:- There are certain rules for oxidation numbers. As per the rule, oxidation number of alkaline earth metals in their compounds is +2.

Oxidation number of oxygen in it's compounds is -2(except peroxides) and the sum of oxidation numbers of all the elements of a neutral compound is zero.

Since, Ca is +2 and O is -2, the oxidation number of S could easily be calculated for the given compound as:

Let's say the oxidation number of S in CaSO_4 is x . Let's make the algebraic equation and solve it.

2+x+4(-2)=0

2+x-8=0

x-6=0

x=+6

Hence. the oxidation number of Ca is +2, O is -2 and S is +6.

All the following involve an increase in entropy except O most endothermic reactions O sublimation O vaporization O combustion
daser333 [38]

Answer:

most endothermic reactions

Explanation:

In endothermic reactions, the entropy of the environment decreases.

The entropy is the measure of the disorder of a specific system.

An endothermic reaction is every chemical reaction in which energy is absorbed.

In a comparison of an endodermic reaction in which energy is released in light or heat form.
