Why is it important that acids and bases have certain naming rules? Why shouldn't we just call them whatever we want?​

Chemistry

Explanation:

This naming can help identify a solution as acid or base (and some of its properties) even before conducting tests. It also allows scientists across the world to collaborate through using a standard naming system.

Naming of the acids and bases is significant in identifying the type and properties of the acid or base. Acids, for example, are named based on the anion attached to the H+ ion in the chemical structure. For example, HCl is called hydrochloric acid because the H+ is bound to a Chloride ion. The suffix for acid is;  –ic, -ate & -ous.

Bases, on the other hand, are named based on the cation attached to the hydroxide eg, CaOH is named calcium hydroxide. The suffix for bases is -ide.

Answer:

<em>It is important to have certain naming rules for both acids or bases so we can distinguish them from one another. </em>

Explanation:

These scientific names are used all over the world. Without these rules, one would not be able to tell the difference between an acid or base. These names not only explain the nature of these substances as well as their reactive properties.  

<u>The name of an acid is classified on the basis of its anions while a base is named using the ionic system. </u>

The examples  of common bases are <em>potassium hydroxide, sodium hydroxide </em>etc while common acids are <em>sulfuric acid, citric acid</em> etc.

What is the concentration of an unknown Mg(OH)2 solution if it took an average of 15.4mL of
vova2212 [387]

Answer:

0.077M

Explanation:

Step 1:

The balanced equation for the reaction. This is given below:

2HCl + Mg(OH)2 —> MgCl2 + 2H2O

From the balanced equation above,

The mole ratio of the acid (nA) = 2

The mole ratio of the base (nB) = 1

Step 2:

Data obtained from the question.

Concentration of base Cb =...?

Volume of base (Vb) = 10mL

Concentration of acid (Ca) = 0.1M

Volume of acid (Va) = 15.4mL

Step 3:

Determination of the concentration of the base, Mg(OH)2.

The concentration of the base can be obtained as follow:

CaVa/CbVb = nA/nB

0.1 x 15.4 /Cb x 10 = 2/1

Cross multiply to express in linear form

Cb x 10 x 2 = 0.1 x 15.4

Divide both side by 10 x 2

Cb = (0.1 x 15.4) /(10 x 2)

Cb = 0.077M

Therefore, the concentration of the base, Mg(OH)2 is 0.077M

A sample of air was collected on a day when the total atmosphere pressure was
zhuklara [117]

Answer:

1. The gas law used: Dalton's law of partial pressure.

2. Pressure of nitrogen = 331 mmHg

Explanation:

From the question given above, the following data were obtained:

Total pressure (Pₜ) = 592 mmHg

Pressure of Oxygen (Pₒ) = 261 mmHg

Pressure of nitrogen (Pₙ) =?

The pressure of nitrogen in the sample can be obtained by using the Dalton's law of partial pressure. This is illustrated below:

Pₜ = Pₒ + Pₙ

592 = 261 + Pₙ

Collect like terms

592 – 261 = Pₙ

331 = Pₙ

Pₙ = 331 mmHg

Therefore, the pressure of nitrogen in the sample is 331 mmHg

After undergoing alpha decay, an atom of radium-226 becomes
Zanzabum
The answer is b. radon-222. The alpha decay means that it will emit an alpha particle when decays. The alpha particle has two protons and two neutrons. So Radium(88) minus two protons will become Radon(86). And the atomic mass will become 226-4=222.

Why are numbers placed before the elements and molecules in a<br>chemical equation?​
Neko [114]

Answer:

the are coefficients for the atom. the tell how many there are.

Explanation:

they tell you how many atoms there are of its type.

ex. 4 C²H³. there are 4 of the c² and h³ (couldn't find a way to use subscript so used the power signs to show.)
