How are mixtures compounds and elements alike?

Answers

Answer 1

Answer: elements make up compounds, and when 2 or more compounds are chemically combined it makes a mixture or they are all matter, they have mass and occupy space

Which of the following requires an increase in kinetic energy?liquid ➡ solid

gas ➡ solid

gas ➡ liquid

solid ➡ gas

Answers

Answer: solid ➡ gas

Explanation:

Solid state : In this state, the molecules are arranged in regular and repeating pattern. The molecules are closely packed that means they are fixed and vibrate in place but they can not move from one place to another. and thus have least kinetic energy.

For example : Copper

Liquid state : In this state, the molecules are present in random and irregular pattern. The molecules are closely packed but they can move from one place to another.. they have intermediate kinetic energy between solids and gases.

For example : water

Gaseous state : In this state, the molecules are present in irregular pattern. The molecules are not closely packed and they can move freely from one place to another and spread out. They have highest kinetic energy.

For example : Helium gas

solid -> gas will need the increase in kinetic energy

Explanation:

This reaction is an example of what type of reaction? H2SO3(aq) H2O(l) + SO2(g)a. a synthesis reaction
b. a disynthesis reaction
c. a combustion reaction
d. a decomposition reaction

Answers

This reaction H2SO3(aq) H2O(l) + SO2(g) is an example of what a decomposition reaction. It is not a replacement reaction because no other compound is involved. It is not a combustion reaction because no oxygen is involved.

Answer: Option (d) is the correct answer.

Explanation:

A chemical reaction in which a compound dissociates to give two different compounds or atoms is known as a dissociation reaction.

For example, $H_(2)SO_(3)(aq) \rightarrow H_(2)O(l) + SO_(2)(g)$

Here, sulfurous acid dissociates into water and sulfur dioxide gas. Both water and sulphur dioxide have different properties than sulfurous acid.

Therefore, we can conclude that the given reaction is an example of a decomposition reaction.

Which formula represents a molecular compound?
(1) Kr (3) N2O4
(2) LiOH (4) NaI

Answers

N2O4 is the only option from the list that represents a molecular compound, since compounds must contain at least two different atoms, although these can be from different groups.

Answer: Option (3) is the correct answer.

Explanation:

A molecular compound is a compound in which atoms used to share electrons and thus results in the formation of covalent bonds.

For example, $N_(2)O_(4)$ is a covalent compound and hence, it is a molecular compound.

Whereas LiOH and NaI are ionic compounds as their atoms has transferred electrons.

Therefore, we can conclude that out of the given options, $N_(2)O_(4)$ is the formula which represents a molecular compound.
