Answer:

La reacción se convierte en reversible porque en un recipiente cerrado el gas no escapa y puede reaccionar con el óxido

Explanation:

Basados en la reacción:

3Fe + 4H₂O → Fe₃O₄ + 4H₂(g)

<em>3 moles de hierro con 4 moles de agua producen 1 mol de óxido de hierro y 4 moles de hidrógeno (gas)</em>

Cuando la reacción se está produciendo con un recipiente abierto, todo el gas de hidrógeno está escapando a la atmósfera y no habrá forma de que reaccione con el óxido de hierro.

Pero, si el recipiente está cerrado, el hidrógeno no podrá escapar y podrá reaccionar con el óxido de hierro, así:

Fe₃O₄ + 4H₂(g) → 3Fe + 4H₂O

De esta manera,

<h3>la reacción se convierte en reversible porque en un recipiente cerrado el gas no escapa y puede reaccionar con el óxido</h3>

If 200.0 g of copper(II) sulfate react with an excess of zinc metal, what is the theoretical yield of copper? 1.253 g 50.72 g 79
Helen [10]
1)we need a balanced equation: CuSO₄ + Zn ---> ZnSO₄ + Cu

2) we need to convert the grams of CuSO₄ to moles using the molar mass. 

molar mass CuSO₄= 63.5 + 32.0 + (4 x 16.0)= 160 g/mol

200.0 g CuSO_4 ( \frac{1 mol}{160 grams} )= 1.25 mol CuSO_4

3) convert moles of CuSO₄ to moles of Cu

1.25 mol CuSO_4 ( \frac{1 mol Cu}{1 mol CuSO_4} )= 1.25 mol Cu

4) convert moles of Cu to grams using it's molar mass.

molar mass Cu= 63.5 g/mol

1.25 mol (\frac{63.5 grams}{1 mol} )= 79.4 grams Cu

I did it step-by-step as the explanation but you can do all of this in one step. 

200.0 g CuSO_4 ( \frac{1 mol CuSO_4}{160 g} ) ( \frac{1 mol Cu}{1 mol CuSO_4} ) ( \frac{63.5 grams}{1 mol Cu} )= 79.4 grams Cu

The reaction of 2-methylbutane with chlorine would yield how many monochloro derivatives (include stereoisomers)?
zimovet [89]
The reaction  of  2  methylbutane  with   chlorine  yield  5 monochloro  derivative.   Methylbutane  has  four  carbon  atoms  which  react with   chlorine.  The  carbon  with antibonding  will  be  chiral   and  it  will react  with  chlorine. there  will  be  four  difference  group  around  chiral  carbon  hence  it  will  have  stereoisomers.
