Based on the reaction below:
Sidana [21]

N₂ + 3H₂ ⇄ 2NH₃ + heat

In the given equilibrium, we notice that the heat is on the right. which means that if the heat requirements don't meet, the reactants on the right will no longer react due to the lack of heat

but because the reactants on the left don't have such weaknesses, they will keep reacting hence producing more and more ammonia until a new equilibrium is reached

where there will be more ammonia and less nitrogen and hydrogen as compared to the equilibrium we had initially

The solubility of CaF2 is 0.00021 mole per liter. What is the solubility product constant for CaF2? A) 7.3 x 10-12 B) 3.7 x 10-1
Naddika [18.5K]

Answer:

B) Ksp = 3.7 E-11

Explanation:

CaF2 ↔ Ca2+  +  2F-

  S            S          2S,,,,,,,,,,,,,,,in the equilibrium

⇒ Ksp = [ Ca2+ ] * [ F- ]²

⇒ Ksp = S * ( 2S )²

⇒ Ksp = 4S³

⇒ Ksp = 4 * ( 0.00021 )³

⇒ Ksp = 4 * 9.261 E-12

⇒ Ksp = 3.704 E-11

How much heat is absorbed when 1 kg of a liquid gets vaporized at its boiling point
inn [45]
22.6 x 10^5 J

‘Heat of vaporization’ is the amount of ‘heat’ required to convert '1g' of mass of a liquid to vapor. Normal “boiling point of water” is 100 C. The heat of vaporization at this temperature is 2260 J/g. It means 2260 J/g of heat is required to convert ‘1g of water’ to 1g of vapor at 100 C. So to convert 1 kg of mass of water or 1000g of water we require 22.6 x 10^5 J of heat.

A liquid in the lab has a density of 1.17 g/cm3. What is the volume in liters of 3.02 kg of the liquid?
Leokris [45]

<u>Answer:</u> The volume of liquid in liters is 2.5812 L.

<u>Explanation:</u>

Density of an object is defined as the ratio of its mass and volume. The chemical equation representing density of an object is:

\text{Density of an object}=\frac{\text{Mass of an object}}{\text{Volume of an object}}

We are given:

Mass of liquid = 3.02 kg = 3020 g     (Conversion factor: 1kg = 1000 g)

Density of liquid = 1.17 g/cm^3

Putting values in above equation, we get:

1.17g/cm^3=\frac{3020g}{\text{Volume of liquid}}\\\\\text{Volume of liquid}=2581.2cm^3

Converting this into liters, we use the conversion factor:

1L=1000cm^3

So, \Rightarrow \frac{1L}{1000cm^3}\times 2581.2cm^3

\Rightarrow 2.5812L

Hence, the volume of the liquid is 2.5812 L.
