Describe the sequence of events in the formation of an evaporite

Answers

Answer 1

Answer: - Water enter from creeks, bringing whatever material it has dissolved in its way

- The materials is being build up throughout time in the lake or sea, causing its salinity to increase

- when this saline solution is evaporated, the ions in the water precipitate, forming an evaporite

Answer 2

Answer:

Sediments are buried, pressure increases, volume of sediment decreases, sandstone compresses, saline solution becomes evaporated,and thenforms an evaporite.

What is an evaporite?

An evaporite can be defined as a mineral deposit containing saline substances that are produced due to the evaporation of a water body.

In this context, the sequence of events in the formation of an evaporite are listed as follows:

Sediments are buried.
Increase pressure pushes the grains closer together.
Decrease in the volume of sediment, which cause fluids between the grains to be squeezed out.
Sandstone are left tightly compressed together.
The saline solution becomes evaporated, and then the ions contained in the water precipitates, forming an evaporite.

What can be concluded if an ion of an element is smaller than an atom of the same element?(1) The ion is negatively charged because it has fewer electrons than the atom.
(2) The ion is negatively charged because it has more electrons than the atom.
(3) The ion is positively charged because it has fewer electrons than the atom.
(4) The ion is positively charged because it has more electrons than the atom.

Answers

The question is,'what can be concluded if the ion of an element is smaller than the atom of the same element'. The correct option is 'the ion is positively charged because it has fewer electrons than the atom. An atom becomes charged either by donation or accepting electrons. When an atom donate electrons, it becomes positively charged and it has less electrons than its atom. For instance, calcium has 20 electrons, it becomes an ion by donating its two electrovalent electrons, thereby having only 18 electrons left. But when an element accepts electrons, it becomes negatively charged and has more electrons than its atom.

The following conclusion can be made if an ion of an element is smaller than an atom of the same element:

$\boxed{\left( 3 \right){\text{ The ion is positively charged because it has fewer electrons than the atom}}{\text{.}}}$

Further explanation:

Ions are the entities with a net electric charge, be it positive or negative. Since positive and negative charges can be present on the ions, ions are of two types-positively charged and negatively charged ions. The ions formed by loss of electrons develop a positive charge and are called cations. But the ions produced by the gain of electrons acquire a negative charge and are called anions.

Since cations are positively charged ions, these have fewer electrons as compared to the corresponding neutral atom. So these ions experience stronger forces of attraction with the atomic nucleus and are smaller in size in size than the parent atom.

Anions are formed by the addition of electrons to the neutral atom. It has more electrons than the parent atom so it feels electron-electron repulsion due to which its size becomes larger than the parent atom.

So cations are smaller than the parent atom of the same element whereas anions are larger than the parent atoms. Therefore if an ion is smaller than the atom, it is positively charged due to the presence of fewer electrons than the parent atom.

In an investigation that uses the scientific method, which step immediately follows making a hypothesis?

Answers

After you make a hypothesis, you then will test the hypothesis. You will test the hypothesis by testing the data that was collected and any additional data that proves that your hypothesis is correct. If your data shows that your hypothesis was not correct, you will then have to collect more data or come up with another hypothesis.

Which of the following is a change from a less condensed to a more condensed state of matter?A.) Boiling
B.) Evaporating
C.) Condensation
D.) Melting

Answers

The answer is C. Condensation is a change from a less condensed to a more condensed state of matter. It is a phase change from the gas state to liquid state. The gas is the less condensed state and the liquid is the more condensed state as compared to gas.

The part of the atom that carries a positive charge is the _____, and the part that carries a neutral charge is the _____.neutron; proton
electron; proton
proton; electron
proton; neutron

Answers

Answer : Option D) Proton and Neutron.

Explanation : The part of the atom that carries a positive charge is the proton, and the part that carries a neutral charge is the neutron.

A proton is a small subatomic particle, denoted by symbol $p or p^(⁺)$ , with a positive electric charge of +1 e elementary charge and a mass which is slightly less than that of a neutron. It is located at the center o atomic nucleus along with neutron. The number of protons are equal to the number of electrons of that atom but are in opposite charges.

A neutron is a subatomic particle of an atom which is of the same mass as that of proton but without an electric charge, it is present in all atomic nuclei except those of ordinary hydrogen. It is also located at the center of an atomic nucleus.

Proton; neutron
Protons have a positive charge
Neutrons are neutral
Electrons have a negative charge :)
