Explain how atomic interactions determine a material to be transparent and opaque

Chemistry
1 answer:
mote1985 [20]3 years ago
5 0

Answer:

The materials are opaque or crystalline from a client to the orientation and type of union between their atoms, forming two types of structures.

These two structures can be crystalline or amorphous.

In the case of being crystalline, these unions do not allow light to pass through the medium of the object or body of said compound, making it totally refract and giving the appearance of OPAQUE.

On the other hand, in those compounds that we call amorphous, the atoms are located in a different way that makes light pass through them, without absorbing or identifying any light beam, so they look transparent.

Explanation:

Example: A glass cup has an amorphous structure, while a porcelain or porcelain plate has a crystalline structure.

In the Fe/Cu Lab for every 1 mole of Fe reacted, 1 mole of Cu is made, therefor, for every 1 gram of Fe used, 1 gram of Cu is ma
Mandarinka [93]

Answer:

Explanation:

Since 1 mole of Fe reacted and 1 mole of Cu is produced.

Mass = molar mass × number of moles

Molar mass of Fe = 56 g/mol

Molar mass of Cu = 63.5 g/mol

Mass of Fe = 56 × 1

= 56 g

Mass of Cu = 63.5 × 1

= 63.5 g

Therefore, the statement is not correct.

For the following equilibrium system, which of the following changes will form more CaCO3? CO2(g) + Ca(OH)2(s) ⇌ CaCO3(s) + H2O(
Talja [164]

Answer: d. Remove one-half of the initial CaCO3.

Explanation: Le Chatelier's principle states that changes on the temperature, pressure, concentration and volume of a system will affect the reaction in an observable way. So in the reaction above:

A decrease in temperature will shift the equilibrium to the left because the reaction is exothermic, which means heat is released during the reaction. In other words, when you decrease temperature of a system, the equilibrium is towards the exothermic reaction;

A change in volume or pressure, will result in a production of more or less moles of gas. A increase in volume or in the partial pressure of CO2, the side which produces more moles of gas will be favored. In the equilibrium above, the shift will be to the left.

A change in concentration will tip the equilibrium towards the change: in this system, removing the product will shift the equilibrium towards the production of more CaCO3 to return to the equilibrium.

So, the correct answer is D. Remove one-half of the initial CaCO3.

In the electron dot notation Be:, the two dots represent valence electrons in the s sublevel. True False
krek1111 [17]

True

Explanation:

In the electron dot notation, the two dots on Be represents valence electrons in the s-sublevel.

The electron dot notation is also known as lewis dot structure.

This notation shows only the chemical symbol surrounded by dots to represent the valence electrons.

The dots are arranged at the four sides of the symbol in pairs called lone pairs. The unpaired ones are the odd electrons.

 For Be, the structure is 1s² 2s²

The 2s sublevel is in the outermost/valence shell and it is made up of two electrons.

It is correct to say that the two dots on Be denotes the valence electrons in the s-sublevel.
