dezoksy [38]

Answer:

I'm not really sure how to answer it but this is the best I can do:

If the capacity of a mass is 1350 and heat is transferred to increase the temperature by 15. degrees Celcius then the amount of heat that needs to be transferred would be about  45 degrees.

Explanation:

I'm sorry if it's wrong or not exactly the way it's supposed to be answered, I'm not very good with math and temperature problems. But i hope it helps! :)

My name is Ann [436]

Answer:

3. four

Explanation:

balanced equation:

  • 2S + 3O2 → 2SO3

∴ moles (n) S = 4 mol

∴ n O2 = 6 mol

limit reagent: S

⇒ mol SO3 = ( 4 mol S )*( 2 mol SO3 / 2 mol S )

⇒ n SO3 = 4 mol SO3
