The percentage purity of the sodium hydroxide will be 37.5%.

option A is correct.

<h3>What is mass percentage?</h3>

Mass percentage is the amount of solute present in per hundred gram of a solution is called Mass percentage of solution.

Mass percentage = mass of component / mass of solution × 100

mass of component = 1.20g

mass of solution = molar mass of NaOH + molar mass of HCl

= 40 + 36.5

= 76.5

substituting the value in the equation,

mass percentage = 1.20 / 76.5

= 37.5%

Therefore, percentage purity of the sodium hydroxide will be 37.5%.

option A is correct.

Consider the following unbalanced chemical equation. C5H12(l) + O2(g) → CO2(g) + H2O(l) If 21.9 grams of pentane (C5H12) are bur

Marina CMI [18]

Answer : The mass of water produced will be 32.78 grams.

Explanation : Given,

Mass of $C_5H_{12}$ = 21.9 g

Molar mass of $C_5H_{12}$ = 72.15 g/mole

Molar mass of $H_2O$ = 18 g/mole

First we have to calculate the moles of $C_5H_{12}$ .

$\text{Moles of }C_5H_{12}=\frac{\text{Mass of }C_5H_{12}}{\text{Molar mass of }C_5H_{12}}=\frac{21.9g}{72.15g/mole}=0.3035moles$

Now we have to calculate the moles of $H_2O$ .

The balanced chemical reaction will be,

$C_5H_{12}(l)+8O_2(g)\rightarrow 5CO_2(g)+6H_2O(l)$

From the balanced reaction we conclude that

As, 1 mole of $C_5H_{12}$ react to give 6 moles of $H_2O$

So, 0.3035 moles of $C_5H_{12}$ react to give $0.3035\times 6=1.821$ moles of $H_2O$

Now we have to calculate the mass of $H_2O$ .

$\text{Mass of }H_2O=\text{Moles of }H_2O\times \text{Molar mass of }H_2O$

$\text{Mass of }H_2O=(1.821mole)\times (18g/mole)=32.78g$

Therefore, the mass of water produced will be 32.78 grams.

1.What is desalination?

Andreas93 [3]

Answer:

1. The process of removal of the dissolved salts from sea/ocean water is called desalination.

2.Well and Spring water contains dissolved impurities but not suspended imputites or germs because they have been filtered through different layers of soil.Thus, well water and spring water is pure and safe to drink.

3 Rain water is the purest form of water.

4.The interconversion of the three state of water aldo occurs in nature which is known as water cycle.

5. a) Due to water cycle, it rains. Raining is very important because agricultural production depends on it.

b) Controls the climatic conditions all over the world.
