Acid and base compounds break up into ions solution.

<h3><u> Explanation:</u></h3>

Acids are the compounds that breaks into hydrogen ions. Bases are those compounds that dissociate into hydroxide or OH - ions. When you put an ionic or electrovalent compound into water , then it breaks apart into two ions.If one of them is H+ ions, then the solution is known to be acidic.

A good example of strong acid is hydrogen chloride which breaks into water and releases ions. If we take the example of bases than if one of the releasing ion is OH- in the solution than the solution is basic . A good example of this is sodium hydroxide (NaOH).

<h3>What is the property of metals?</h3>

We know that the properties of metals can be used to identify an unknown substances as a metal. We know that metals are able to react with acids to liberate the metal salt and hydrogen gas. Metals do not react with bases because they can not accept electrons.

Metalloids are generally amphoteric in nature. They can react with both the acid and the basses to form compounds. The nonmetals do not react with acid or base.

Looking at the result, we are told that the entry in the second row have the entries nothing, nothing, nothing. If this is the outcome, then it follows that the element should be placed in the column for metalloids.

Calculate the volume (liters) of solution that can be prepared from 180. grams of K2Cr2O7 for a 0.200M solution.

Sladkaya [172]

Answer:

The volume of the solution is 0.305 liters.

Explanation:

Molar mass is the amount of mass that a substance contains in one mole. The molar mass of K₂Cr₂O₇ is 294 g / mole. Then you can apply the following rule of three: if by definition of molar mass 294 grams of the compound are contained in 1 mole, 180 grams are contained in how many moles?

$moles=\frac{180 grams*1mole}{294 grams}$

moles= 0.61

Molarity is a measure of the concentration of a substance that is defined as the number of moles contained in a certain volume. So, the molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:

$molarity=\frac{number of moles of solute}{volume}$
