Samantha can separate the mixture of titanium dioxide from the liquid by the method of filtration using a filter paper.

<h3>What are mixtures?</h3>

Mixtures are substances consisting of two or more substances physically mixed together.

Mixtures can be separated by physical methods.

Titanium dioxide and water is a mixture.

Since titanium dioxide is insoluble in water, it can be easily separated by filtration.

Therefore, Samantha can separate the titanium dioxide from the liquid by the method of filtration using a filter paper.

Answer:

2×10² cg

Explanation:

We'll begin by converting each of the above to the same unit of measurement.

In this case, we shall convert each of the above to kg. This can be obtained as follow:

Conversion of cg to kg

1 cg = 1×10¯⁵ Kg

Therefore,

2×10² cg = 2×10² × 1×10¯⁵

2×10² cg = 0.002 kg

Conversion of dg to Kg

1 dg = 1×10¯⁴ kg

Therefore,

10 dg = 10 × 1×10¯⁴

10 dg = 0.001 kg

Conversion of mg to kg.

1 mg = 1×10¯⁶ Kg

Therefore,

2×10² mg = 2×10² × 1×10¯⁶

2×10² mg = 0.0002 kg

Conversion of ng to kg

1 ng = 1×10¯¹² kg

Therefore,

1×10⁵ ng = 1×10⁵ × 1×10¯¹²

1×10⁵ ng = 0.0000001 Kg

Summary

1. 2×10² cg = 0.002 kg

2. 10 dg = 0.001 kg

3. 2×10² mg = 0.0002 kg

4. 0.001 kg

5. 1×10⁵ ng = 0.0000001 Kg

From the above calculation, 2×10² cg is the highest mass.

Mama L [17]

Explanation:

Nitrous oxide or dinitrogen monoxide can be simple be prepared by the decomposition of ammonium nitrate in the following way -

<u>The reaction is as follows -</u>

NH₄NO₃  ---------------->  N₂O + H₂O

This is the unbalanced reaction as was asked in the question , without mentioning the states of matter .

The reaction is carried out in an anhydrous condition ,since , ammonium nitrate can explode on heating .

Determine the number of moles of air present in 1.35 l at 750 torr and 17.0°c. ideal gas law formula: pv = nrt(r = 62.396 l•torr
Tatiana [17]

The number of moles of air present is 0.056 mole

<h3>What is the ideal gas equation?</h3>

The ideal gas is one in which molecules do not attract or repel each other.Many gases like oxygen,nitrogen, carbon di oxide can be treated as the ideal gases as particular temperature and pressure.The real gases at high temperature and lower pressure can be treated as ideal gases.

The given data in the question is

Volume = 1.35 L

Pressure (P) = 750 torr

Temperature (T) = 17 °C = 17 + 273 = 290 K

Gas constant (R) = 62.396 L•torr/mol•K

The number of moles (n) =?

How to determine the number of moles:

The number of moles present can be obtained by using the ideal gas equation as illustrated below:

PV=nRT

Divide both sides by RT

n=\dfrac{PV}{RT}

n=\dfrac{(750\times 1.350}{62.396\times 290)}

n=0.056\ moles

Hence, the number of moles of air present is 0.056 mole
