A solution contains 0.2 moles of hydrochloric acid. The volume of the solution is 100cm3. What is its concentration in mol/dm³?
Umnica [9.8K]
Answer= 2 mol/dm^3

Explanation:-
Firstly, we convert the volume, which is in cm^3 to dm^3. To do that divide number in cm^3 by 1000:
100/1000= 0.1 dm^3

Formula for concentration is:
Concentration= No. of moles/ Volume

So,
Concentration= 0.2/0.1

Answer= 2 mol/dm^3

Mg + 2H2O -----&gt; Mg (OH)2 + H2<br><br><br> Write it in word problem
diamong [38]

The word problem format to the task given above is: When magnesium reacts with steam, it produces magnesium hydroxide and liberate hydrogen gas.

<h3>How magnesium hydroxide is formed?</h3>

It happens that magnesium is an alkali earth metal and react with water in the gaseous state to librate hydrogen gas, when this reaction occurs, it results in the formation of magnesium hydroxide.

The chemical equation between magnesium and water is given below:

Mg + 2H₂O -----> Mg (OH)₂ + H₂

So therefore, we can accurately deduced that magnesium hydroxide is produced when magnesium is disolved in water.

What is the Golden Rule of Solubility? A. polar dissolves nonpolar. B. nonpolar dissolves polar. C. like dissolves unlike D. lik
DerKrebs [107]

Answer: D. like dissolves like

Explanation:

The solubility of substances is governed by: Like dissolves like, which states that polar compounds are soluble in polar solvents and non polar compounds are soluble in non polar solvents.

Hydrocarbons are non polar in nature due to less difference between the electronegativities of carbon and hydrogen and thus are soluble in non polar solvents only.

Ionic compounds which are formed by elements with high electronegativity difference are polar in nature and thus dissolve in polar solvents.

Example: NaCl in water.
