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.

Which one of the following substances is the product of this combination reaction? Al (s) + I2 (s) → ________(A) AlI2(B) AlI(C)
Slav-nsk [51]

Answer:

AlI_3

Explanation:

Combination reactions are the reactions in which two or more atoms/ molecules combine to give a single product.

Aluminum metal combines with iodine to given aluminium iodide.

Aluminium has a valency of 3 and iodine has valency of 1, so the formula is AlI_3

The reaction is shown below as:

Al_{(s)}+I_2_{(s)}\rightarrow AlI_3_{(s)}
