1) Analysis of the gases in a sealed reaction vessel containing NH3, N2, and H2 at equilibrium at 400°C established the concentration of N2 to be 1.2 M and the concentration of H2 to be 0.24 M

N2(g) + 3H2(g) ←→ 2NH3(g)

Kc= 0.5 at 400 C

Calculate the equilibrium molar concentration of NH,. 

2) How will the acquisition and diffusion of scientific knowledge impact the future of religion in the world?

3) Determine the quantity of (g) pure MGSO4 in 2.4g of MGSO4 . 7H2O

 

Answer:

1.

At equilibrium

N2(g) +3H2(g) -------------------> 2 NH3 (g)

1.2 0.24 x equilibrium concentrations

Kc = [NH3]² / [N2][H2]³

0.5 = x2/ (1.2) (0.24)³

or x = 0.09107 M

Thus the equilibrium molar concentration of NH3 = 0.09107M

2.

The acquisition and diffusion of scientific knowledge affect the religion in the following ways -

1. It may question the validity of religion in the current world because there are many religious rituals which can not be justified int he current world. Example - Sharia law in Muslims, Manusmriti in Hinduism etc

2. The religions were acting as a powerful tool in the past in the hands of the rulers since they could control his people by showing fear of religion but now since there is no king and the world is more multipolar thus every person in the world has freedom to speak freely and thus there can come a time when people totally ignore religious rituals which are life taking also sometimes (example giving religious offerings of animals and sometime human also)

3. In the early times, people used to consider sun, moon, rain etc as God (Example - In the Roman and Greek literatures) but now since we know how sun, moon, rainfall etc affect the earth and there are scientific ways for every activity to occur and thus, we can no more consider them God which is going to have huge impact on religion.

1.172 grams of MgSO₄

Step-by-step explanation

Determine the quantity of (g) pure MgSO₄ in 2.4g of MgSO₄ . 7H₂O

Molar mass MgSO₄ = 24.305 + 32.065 + 4x16 = 120.365 g/mol

Molar mass MgSO₄ . 7H₂O = 24.305 + 32.065 + 4x16 + 14x1.01 + 7x16 = 246.51

Quantity = ?2.4g⋅(120.365g/mol?/246.51g/mol)?

= 1.172 grams of MgSO₄
