Question 6: Iron metal and chlorine gas react to form iron (III) chloride: 2 Fe(s) + 3 Cl2 (g) → 2 FeCl3 (s)
Bas_tet [7]

10 gm of Fe will consumes 19 gm Cl₂ and will produces 29 gm FeCl₃.

What ois Theoretical yield ?

The quantity of a product obtained from a reaction is expressed in terms of the yield of the reaction.

The amount of product predicted by stoichiometry is called the theoretical yield, whereas the amount obtained actually is called the actual yield.

  • As 2 moles (111.68 g) of Fe consumes 213 gm of Cl₂ to produce 2FeCl₃

Therefore ,

10 gm of Fe will consumes = 213 / 111.68 x 10 = 19 gm Cl₂

  • As 2 moles (111.68 g) of Fe produces 2 mole (324 gm) of FeCl₃

Therefore ,

10 gm of Fe will produces = 324 / 111.68 x 10 = 29 gm FeCl₃

Hence , 10 gm of Fe will consumes 19 gm Cl₂ and will produces 29 gm FeCl₃.

14. Describe the phase change during:<br> Melting:<br> Boiling:<br> Condensing:<br> Freezing
Sergio [31]

Answer:

Explanation:

Melting: it is a phase change from solid to liquid. It is usually attained when a substance reaches it melting point as heat is supplied to it. The vibrating particles break loose and begins to move like a liquid. Melting of iron is an example.

Boiling; is a phase change from liquid to gases. When substances reaches their boiling points when heat is supplied they begin to boil and form gases. An example is the boiling of water. Boiling usually occurs when the vapor pressure is equal to the atmospheric pressure around.

Condensing: is a phase change from gas to liquid. When gases are cooled they condense back to liquid. Example is rain clouds.

Freezing: is a phase change from liquid to solid.

B) How many moles of Na2O can be produced from 13.5 moles Na?
dolphi86 [110]

Answer: 6.75 moles of Na_2O can be produced from 13.5 moles Na

Explanation:

The balanced chemical equation  for formation of Na_2O from Na is:

4Na+O_2\rightarrow 2Na_2O  

According to stoichiometry :

4 moles of Na give = 2 moles of Na_2O

Thus 13.5 moles of Na give =\frac{2}{4}\times 13.5=6.75moles  of Na_2O  

Thus 6.75 moles of Na_2O can be produced from 13.5 moles Na
