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 .

I still see your shadows why cant I get over you. You were my first love and my last love. All this love is lost because I cant

Arlecino [84]

The reason you are holding on to that might be because you have hope that this person who left you might come back. If they left you they aren't worth hoping for them to come back. This is a question that probably should be asked elsewhere but hope I can help.

Which of the water samples described below has the greatest average kinetic energy per molecule? A. 1 liter of water at a temper

Triss [41]

Answer:

A. 1 liter of water at temperature 75°C

Explanation:

According to kinetic molecular theory average kinetic energy of molecules are directly proportional to absolute temperature.

the quantity of the sample does't depend on kinetic energy only temperature

does so the choice with highest temperature is the correct choice

∵ 1 liter water at 75°C has highest average kinetic energy per molecule
