Chlorine is used to make bleach solutions containing 5.25% NaClO (by mass). Assuming 100% yield in the reaction producing NaClO

Archy [21]

To make 1000. L of bleach solution 1.69×10⁴ L of Cl₂(g) at STP will be needed .

<h3>What is Balanced chemical equation?</h3>

A balance chemical equation is an equation that contain same number of atoms as well as of each element on each side of reaction.

<h3>What is Density?</h3>

It is ratio of mass to the volume.

Density= $\frac{Mass}{Volume}$

Now,

The balanced chemical equation of preparing bleach from chlorine is as follow:

Cl₂(g) + 2NaOH(aq) → NaClO(aq) + NaCl(aq) + H₂O(l)

Now,

To calculate the Moles of NaClO in 1000L solution, first calculate it's mass.

Mass of NaClO = Density × Volume

= 1.07 $\frac{g}{ml}$ × 1000L × $\frac{1000mL}{1L}$ × $\frac{5.25}{100}$

= 56175g

Now, we have to calculate moles of NaClO

Hence,

Moles of NaClO = $\frac{amount of NaClO}{molar mass of NaClO}$

= $\frac{56175g}{74.44\frac{g}{mol} }$

= 754.63 mol

Now,

According to the reaction number of moles of Cl₂ is equal to the number of moles of NaClO.

Hence,

moles of Cl₂ = 754.63 mol

Now , in order to calculate litres of Cl₂ at STP,

We know that

1 mol Cl₂ = 22.4 L of Cl₂

754.63 mol of Cl₂ = 754.63 mol × 22.4 L

= 1.69×10⁴ L of Cl₂

Thus from the above conclusion we can say that , to make 1000. L of bleach solution 1.69×10⁴ L of Cl₂(g) at STP will be needed .

Find the density of a cube on Earth that weighs 1.5 kg and has a side-length of 10 cm.

Inga [223]

Answer:

1.5g/cm³

Explanation:

density=mass÷volume

mass= 1.5kg (<em>c</em><em>h</em><em>a</em><em>n</em><em>g</em><em>e</em><em> </em><em>i</em><em>n</em><em>t</em><em>o</em><em> </em><em>g</em>) = 1500g

volume of the cube = 10×10×10 = 1000cm³

density= divide 1500g÷1000cm = 1.5g/cm³

<h2>Density= 1.5g/cm³</h2>

How does furring occur in kettles from hard water?

ZanzabumX [31]

Hard water contains high levels of minerals such as magnesium and calcium and can be a real pain to remove if left untreated. When hard water is boiled in an electric kettle, these minerals do not evaporate like the water does but instead remains in the kettle.

You are given a sample resembling silver. Which of the following properties could be used to help determine whether the sample i

defon

Answer:

the density of the sample - the melting point of the sample

Explanation:

Intrinsic property is the property of matter which exists itself or within subject. In other words, it do not depend on the mass of the sample. An extrinsic property is not inherent or essential to subject which is being characterized. In other words, it depend on the mass of the sample.

For example,

Density, melting point are example of intrinsic property. Whereas, weight, volume are an example of extrinsic property.

Intrinsic properties helps to determine the matter. Thus, density of sample and melting point of sample is the answer.
