Give an example of a 2 phase mixture and describe how you would separate the substances

Chemistry

<span><u><em>First, we should define what a mixture and a two-phase mixture mean.</em></u>
<u><em>A mixture</em></u> is a combination of two or more substances without any chemical reaction occurring between them. Components of a mixture can be separated using physical methods such as heating, filtering, evaporation, .... etc
<em><u>A two-phase mixture</u></em> is a type of mixture that contains two different phases of matter, for example solid and liquid phases in one mixture or liquid and gas phases in one mixture.

<u><em>Now, we can give examples of two-phase mixtures and mention how to separate them:</em></u>
<u><em>A mixture of sand and water</em></u> is considered a two-phase mixture (sand is sold and water is a liquid).
<u><em>The components can easily be separated</em></u> using filtration where the sand will remain on the filter paper and water will pass.

Another example is <u><em>a mixture of sugar and water</em></u> (sugar is a solid and water is a liquid).
<u><em>The components can be separated </em></u>by heating. We can eat the mixture until water evaporates and the sugar is precipitated. The evaporated water can then be condensed into a different container.

Hope this helps :)</span>

$$\boxed{{\text{Mixture of sand and water}}}$$ is an example of two-phase mixture and this can be separated by $$\boxed{{\text{filtration}}}$$ .

Further explanation:

Mixture:

The material that is made up of two or more substances is called a mixture. It has no fixed formula and its composition is also varied. All the individual constituents retain their properties after the formation of the mixture.

<u>Types of mixtures: </u>

<u> </u>

1. Homogeneous mixtures

<em>Homogeneous </em>is a Latin word that means the <em>same</em>. These mixtures have a <em>uniform composition</em> throughout. These types of mixtures consist of a single phase only. Air, orange juice and blood are the examples of a homogenous mixture.

2. Heterogeneous mixtures

<em>Heterogeneous </em>is a Latin word that means <em>different</em>. These mixtures that have <em>non-uniform composition </em> throughout. These mixtures have more than one phase. Concrete, soda and chocolate chip cookies are the examples of a heterogeneous mixture.

Characteristics of mixtures:

1. It has a variable composition and has no formula.

2. Mixtures are not formed by any chemical reactions.

3. Mixtures can be either homogeneous or heterogeneous.

4. The constituents of the mixtures can be separated by physical methods such as filtration, heating, drying, distillation, crystallization.

5. The properties of the individual particles of the mixture are retained even after the formation of mixtures.

A mixture of sand and water is an example of a two-phase mixture. Here sand is a solid whereas water is a liquid. The components of the mixture are separated by filtration. Sand will remain on the surface of filter paper while water passes through it.

Which of the following possess the greatest concentration of hydroxide ions?
jek_recluse [69]

Answer : The correct option is (d) a solution of 0.10 M NaOH

Explanation :

<u>(a) a solution of pH 3.0</u>

First we have to calculate the pOH.

pH+pOH=14\\\\pOH=14-pH\\\\pOH=14-3.0=11

Now we have to calculate the OH^- concentration.

pOH=-\log [OH^-]

11=-\log [OH^-]

[OH^-]=1.0\times 10^{-11}M

Thus, the OH^- concentration is, 1.0\times 10^{-11}M

<u>(b) a solution of 0.10 M NH_3</u>

As we know that 1 mole of NH_3 is a weak base. So, in a solution it will not dissociates completely.

So, the OH^- concentration will be less than 0.10 M

<u>(c) a solution with a pOH of 12.</u>

We have to calculate the OH^- concentration.

pOH=-\log [OH^-]

12=-\log [OH^-]

[OH^-]=1.0\times 10^{-12}M

Thus, the OH^- concentration is, 1.0\times 10^{-12}M

<u>(d) a solution of 0.10 M NaOH</u>

As we know that NaOH is a strong base. So, it dissociates to give Na^+ ion and OH^- ion.

So, 0.10 M of NaOH in a solution dissociates to give 0.10 M of Na^+ ion and 0.10 M of OH^- ion.

Thus, the OH^- concentration is, 0.10 M

<u>(e) a 1\times 10^{-4}M solution of HNO_2</u>

As we know that 1 mole of HNO_2 in a solution dissociates to give 1 mole of H^+ ion and 1 mole of NO_2^- ion.

So, 1\times 10^{-4}M of HNO_2 in a solution dissociates to give 1\times 10^{-4}M of H^+ ion and 1\times 10^{-4}M of NO_2^- ion.

The concentration of H^+ ion is 1\times 10^{-4}M

First we have to calculate the pH.

pH=-\log [H^+]

pH=-\log (1.0\times 10^{-4})

pH=4

Now we have to calculate the pOH.

pH+pOH=14\\\\pOH=14-pH\\\\pOH=14-4=10

Now we have to calculate the OH^- concentration.

pOH=-\log [OH^-]

10=-\log [OH^-]

[OH^-]=1.0\times 10^{-10}M

Thus, the OH^- concentration is, 1.0\times 10^{-10}M

From this we conclude that, a solution of 0.10 M NaOH possess the greatest concentration of hydroxide ions.

Hence, the correct option is (d)

b) If 1.5 mole of oxygen reacted, how many mole of iron (III) oxide would be formed from the reaction?
lyudmila [28]

Answer:

If there reacted 1.5 moles of O2, there will be produced 1.0 mol of Fe2O3

Explanation:

Step 1: Data given

Number of moles oxygen reacted = 1.5 moles

Step 2: The balanced equation

4Fe + 3O2 → 2Fe2O3

Step 3: Calculate moles of Fe2O3

For 4 moles Fe consumed, we need 3 moles of O2 to produce 2 moles of Fe2O3

For 1.5 moles O2 consumed, we'll have 2/3 * 1.5 = 1.0 mol of Fe2O3

If there reacted 1.5 moles of O2, there will be produced 1.0 mol of Fe2O3
