The chemical formula for the ionic compound aluminum sulfite is Al2(SO3)3. Explain why there are 2 cations for every 3 anions in this compound.

Answers

Answer 1

Answer:

Explanation:

While trying to write the chemical formula for a compound (a neutral molecule), one must identify and exchange the charge of the cation with that of the anion to become the subscript of one other. For example

Aluminium oxide has Aluminium (Al) and oxygen (O); since Al has a charge of 3+ (the cation) and O has a charge of 2- (the anion), the compound would have it's charges as Al³⁺O²⁻ and when the charges are exchanged to there subscripts, it would form Al₂O₃; thus there would be two cations of aluminium for every three anions of oxygen in order to have a neutral molecule.

This same explanation can be given to Aluminium sulfite. Aluminium sulfite has Aluminium (Al) and sulfite (SO₃). Al has a charge of 3+ (cation) while sulfite has a charge of 2- (anion), with the compound having it's charges as Al³⁺(SO₃)²⁻ and when the charges are exchanged to there subscripts, it would form Al₂(SO₃)₃ and would thus have 2 cations of aluminium (Al³⁺) for every 3 anions of sulfite (SO₃³⁻) in order to have a neutral molecule.

Answer:

When we kick the ball, the force we apply to it causes it to accelerate from a speed of 0 to a speed of dozens of kilometers per hour. When the ball is released from the foot, it begins to decelerate (negative acceleration) due to the force of friction that is exerted upon it (as we observed in the previous example).

What could cause the Earth's crust to become a liquid?​

Answers

Answer:

Oceanic crust, extending 5-10 kilometers (3-6 kilometers) beneath the ocean floor, is mostly composed of different types of basalts. Geologists often refer to the rocks of the oceanic crust as “sima.” Sima stands for silicate and magnesium, the most abundant minerals in oceanic crust. (Basalts are a sima rocks.) Oceanic crust is dense, almost 3 grams per cubic centimeter (1.7 ounces per cubic inch).

Oceanic crust is constantly formed at mid-ocean ridges, where tectonic plates are tearing apart from each other. As magma that wells up from these rifts in Earth’s surface cools, it becomes young oceanic crust. The age and density of oceanic crust increases with distance from mid-ocean ridges.

Just as oceanic crust is formed at mid-ocean ridges, it is destroyed in subduction zones. Subduction is the important geologic process in which a tectonic plate made of dense lithospheric material melts or falls below a plate made of less-dense lithosphere at a convergent plate boundary.

At convergent plate boundaries between continental and oceanic lithosphere, the dense oceanic lithosphere (including the crust) always subducts beneath the continental. In the northwestern United States, for example, the oceanic Juan de Fuca plate subducts beneath the continental North American plate. At convergent boundaries between two plates carrying oceanic lithosphere, the denser (usually the larger and deeper ocean basin) subducts. In the Japan Trench, the dense Pacific plate subducts beneath the less-dense Okhotsk plate.

What is the atomic model?

The atomic model is the representation of the atom of the element along with the sub-atomic particles. The first model was given by Dalton, which stated that matter is composed of atoms.

Later Thomson discovered the presence of the electron present in the sea of the positive charges. In addition, Rutherford gave the presence of the positive nucleus in the middle of the atom.

Bohr's model gave the presence of the electron in the orbit of the atom around the nucleus. At last, the current atomic model was given by Schrödinger and is known as the electron cloud model.

Therefore, option C. Gina should Switch 4 (Schrödinger' model) with model 5 ( Bohr 's model).

Carbon is stored in leaves in various forms, such as sugar. When leaves decay,they lose mass. Which of the following sentences explains what happens to the carbon that is stored in leaves when they decay? * 1 point

Answers

Answer:

This question lacks options, however, it can be answered based in general understanding. The answer is:

The carbon is released into the atmosphere and soil during decomposition

Explanation:

Carbon is an important element that makes up the biomass of living organisms. Organisms like plants as described in this question, store carbon as sugars, which they synthesized during photosynthesis. However, when they decompose/decay, they lose this carbon content.

Decomposition is the process carried out by microbes such as fungi, bacteria etc involving the breaking down of an organic molecule into inorganic ones. Hence, when leaves of a plant die, they undergo decomposition i.e. the carbon content in their leaves present as sugar (organic molecules) is broken down to release the carbon in form of carbon dioxide, into the atmosphere, soil etc. Hence, the carbon that is stored in leaves are RELEASED when they decay causing them to lose mass.

8. If a sample of chloroform is initially at 25°C, what is its final temperature if 150.0 g of chloroform
absorbs 1.0 kilojoules of heat, and the specific heat of chloroform is 00.96 J/gºC?

Answers

Answer:

The final temperature is 31.95° C.

Explanation:

Given that,

Initial temperature of a sample of chloroform, [tex]T_i=25^{\circ} C[/tex]

Mass of chloroform, m = 150 g

It absorbs 1 kJ of heat, Q = 10³ J

The specific heat of chloroform, c = 00.96 J/gºC

We need to find the final temperature. The heat absorbed by an object in terms of specific heat is given by :

[tex]Q=mc\Delta T\\\\Q=mc(T_f-T_i)\\\\\dfrac{Q}{mc}+T_i=T_f\\\\T_f=\dfrac{10^3}{150\times 0.96}+25\\\\=31.95^{\circ} C[/tex]

So, the final temperature is 31.95° C.

An ice skater moves back and forth on an ice rink. She speeds up on the straight portion of the rink. She slows down near each end of the rink and then turns around. Which claim supported by evidence?

Answers

The options are;

A) The skater experiences acceleration both while skating in a straight line and while making her turn.

B) Because the skater does not change her direction or speed, she does not experience acceleration.

C) The skater only experiences acceleration when she is turning.

D) The skater only experiences acceleration while skating in a straight line.

Answer:

A: The skater experiences acceleration both while skating in a straight line and while making her turn

Explanation:

We are told that She speeds up on the straight portion of the rink. This means that she experienced an acceleration since the speed was not constant but gradually increasing.

Also, we are told that She slows down near each end of the rink and then turns around. This means that she reduced speed before turning and it means there was also an acceleration as well when making the turn.

Thus, she experience acceleration both in the straight line and when making turn.
