Which corresponds to the composition of the ion typically formed by magnesium?

1 answer:

3 0

The ion composition of Magnesium is 12,10, 2+.
Magnesium is a chemical element with symbol Mg and an atomic number 12, it has 12 protons, and 12 electrons with a chemical configuration of 2:8:2. It requires to loose two electrons to form a stable configuration forming a cation (positively charged ion) with a charge of +2 and a configuration of 2:8 ( 12 protons and 10 electrons).

What is the chemical equation for diphosphorus trioxide + water ---> phosphorous acid?

Dmitriy789 [7]

Your answer is $P_{2}O_{3}+3H_{2}O\rightarrow\ 2H_{3}PO_{3}$

but if you are looking for some explanation check description below :)

Diphosphorus trioxide formula is:

$P_{2}O_{3}$

Di stands from 2 atoms of something, in this case we have 2 atoms of Phosphorus.

Trioxide means that we have 3 atoms of oxygen in this substance that's why we have: $P_{2}O_{3}$

And water is just $H_{2}O$

Unbalanced formula is:

$P_{2}O_{3}+H_{2}O\rightarrow\ H_{3}PO_{3}$

Now we need to balance this equation

On left hand side we have 2 atoms of Phosphorus, on right hand side we have just one atom of Phosphorus, that's why we need to put 2 before $H_{3}PO_{3}$

Now we need to count all atoms of oxygen and hydrogen and make it equal on both side.

So we need to put 3 on left hand side before water to make this equation balanced.
That's why correct answer is:
$P_{2}O_{3}+3H_{2}O\rightarrow\2H_{3}PO_{3}$

The volume of the granite as

Trava [24]

The volume of the granite as determined by water displacement is 9.35 mL. This value in cm³ is 9.35cm³.

<h3>How to calculate volume in cm³?</h3>

The conversion factor of mL and cm³ is given as follows: 1 mL = 1 cm³

According to this question, the volume of the granite as determined by water displacement is 9.35 mL.

This value in cm³ can be converted as follows:

9.35mL × 1 = 9.35cm³

Therefore, the volume of the granite as determined by water displacement is 9.35 mL. This value in cm³ is 9.35cm³.

Which compound is an electrolyte?<br> (1) C6H12O6 (3) CaCl2<br> (2) CH3OH (4) CCl4

slavikrds [6]

I think the correct answer is option 3. CaCl2 is the compound that is an electrolyte when dissolved in water. An electrolyte is a substance that conducts electricity in solution. Calcium Chloride when in solution dissociates into ions which allows the flow of current in the solution.

Create a comic strip that follows the journey of energy from the sun as it travels through the humpback whale

Arisa [49]

The path of energy flow from the sun to the humpback whale is as follows:

Sun---> Plankton ---> Small fishes ---> Humpback whale.

<h3>What is energy?</h3>

Energy is the ability to do work.

The primary source of energy on the earth is the sun.

The energy from the sun is used by producers to produce food on which other organisms depend on.

The energy from the sun gets to the humpback whale through producers such as plankton.

The path of energy flow from the sun to the humpback whale is as follows:

Sun---> Plankton ---> Small fishes ---> Humpback whale.
