Answer:

Δ h = 2958.9 kJ/kg

Explanation:

initial state

T₁ = 50⁰C

P₁ = 1 bar

from steam table , Enthalpy at 50⁰C and 1 bar

h₁ = 208.785 kJ/kg

final state

T₂ = 350⁰C

P₂ = 5 bar

from steam table , Enthalpy at 350⁰C and 5 bar

h₂ = 3167.75 kJ/kg

change in entalpy for the process

Δ h = h₂  - h₁

      = 3167.75  - 208.785

 Δ h = 2958.965 kJ/kg

the change in enthalpy is equal to  Δ h = 2958.9 kJ/kg

Would it be C..? <br> More NO2 and SO2 would form..help..please and thank you
Scorpion4ik [409]

Answer:

C. More NO2 and SO2 will form

Explanation:

Le Chatelier's Principle : It  predicts the behavior of equilibrium due to change in pressure , temperature , volume , concentration etc

It states that When external changes are introduced in the equilibrium then it will shift the equilibrium in a direction to reduce the change.

In given Reaction SO3 is introduced(increased) .

So equilibrium will shift in the direction where SO3 should be consumed(decreased)

Hence the equilibrium will go in backward direction , i.e

NO + SO_{3} \rightarrow NO_{2} + SO_{2}

So more and more Of NO2 and SO2 will form

Why is our mindset more important when you try to learn remotely than when you are learning face to face?
Marrrta [24]

Answer:

It is more important because of the freedom.

Explanation:

While at home you can do your work of course... but you could lay down, take a nap. You could get on the game, play around. You could draw, and fiddle and dance and do WHATEVER you want with no teacher to stop you so you have to be your own motivation. You have to be your own teacher or its VERY easy to fail.
