Answer: Second option is  correct.

Explanation:

Filtration is the method of removing impurities solid particles from liquid.

Distillation is the method of removing impurities in a boiling liquid mixture.

Osmosis is the movement of water from low concentration to high concentration through a plasma membrane.

Reverse osmosis is the method of purification of water to remove ions and unnecessary molecules from drinking water.

We have given the situation that "There is a water sample contaminated with salt and micro organisms."

We need to purify the water.

Filtration is the best method to purify the water and remove the salt and micro organisms.

As there is slight difference between filtration and distillation.

In distillation we need to boil the water , so there heat is needed for this whereas in filtration, it just remove solid from fluid without being heated.

Hence, Second option is  correct.

The steps required to prepare 200.0 mL of an aqueous solution of iron (III) chloride, at a concentration of 1.25x10^-2 M. Please
Yanka [14]

Answer:

In order to prepare 200.0 mL of an aqueous solution of iron (III) chloride, at a concentration of 1.25 x 10⁻² M, you need to weight 0.4055 g of FeCl₃ and add to 200.0 mL of water.

Explanation:

Concentration: 1.25 x 10⁻² M

1,25 x 10⁻² mol FeCl₃ ___ 1000 mL

              x                   ___ 200.0 mL

         x = 2.5 x 10⁻³ mol FeCl₃

Mass of FeCl₃:

1 mol FeCl₃ _____________ 162.2 g

2.5 x 10⁻³ mol FeCl₃ _______    y

                  y = 0.4055 g FeCl₃

The percent composition of all elements in HClO3 is:
ser-zykov [4K]
The answer is <span>b. 1% H, 42% Cl, 57% O.</span>

Let's first calculate a molar mass (M) of HClO₃. <span>Molar mass is a mass of 1 mole of a substance. It can be expressed as the sum of relative atomic masses (Ar), which are masses of atoms of the elements:
</span>M(HClO₃) = Ar(H) + Ar(Cl) + 3Ar(O)

Ar(H) = 1 u 
Ar(Cl) = 35.5 u
Ar(O) = 16 u
M(HClO₃) = Ar(H) + Ar(Cl) + 3Ar(O) = 1 + 35.5 + 3 · <span>16 = 84.5 u

Now, we just need to calculate mass percent of each element using the proportion:
Ar : x = M : 100%                   </span>⇒      x = Ar ÷ M · 100%

Hydrogen: x = Ar(H) ÷ M · 100% = 1 ÷ 84.5 · 100% = 1.2% ≈ 1%
Chlorine: x = Ar(Cl) ÷ M · 100% = 35.5 ÷ 84.5 <span>· 100% = 42%
</span>Oxygen: x = 3Ar(O) ÷ M · 100% = 48 ÷ 84.5 · 100% = 56.8% ≈ 57%
