Answer :

(a) displacement reaction

(b) combination reaction

(c) disproportionation reaction

(d) displacement reaction

Explanation :

(a) The given balanced chemical reaction is,

Fe+H_2SO_4\rightarrow FeSO_4+H_2

This reaction is a single replacement reaction or displacement in which the the more reactive element (Fe) replace the less reactive element (H).

(b) The given balanced chemical reaction is,

S+3F_2\rightarrow SF_6

This reaction is a combination reaction in which the two reactants molecule combine to form a large molecule or single product.

(c) The given balanced chemical reaction is,

2CuCl_2\rightarrow Cu+CuCl_2

This reaction is a disproportionation reaction in which the chemical species gets oxidized and reduced simultaneously.  It is also considered as a redox reaction.

(d) The given balanced chemical reaction is,

2Ag+PtCl_2\rightarrow 2AgCl+Pt

This reaction is a single replacement reaction or displacement in which the the more reactive element (Ag) replace the less reactive element (Pt).

6.5 Moles of Al reacts with 7.2 Moles of H2O What is the limiting reactant and calculate the Theoretical Yield?
SVEN [57.7K]

Answer:

H₂O is the limiting reactant

Theoretical yield of 240 g Al₂O₃ and 14 g H₂

Explanation:

Find how many moles of one reactant is needed to completely react with the other.

6.5 mol Al × (3 mol H₂O / 2 mol Al) = 9.75 mol H₂O

We need 9.75 mol of H₂O to completely react with 6.5 mol of Al.  But we only have 7.2 mol of H₂O.  Therefore, H₂O is the limiting reactant.

Now find the theoretical yield:

7.2 mol H₂O × (1 mol Al₂O₃ / 3 mol H₂O) × (102 g Al₂O₃ / mol Al₂O₃) ≈ 240 g Al₂O₃

7.2 mol H₂O × (3 mol H₂ / 3 mol H₂O) × (2 g H₂ / mol H₂) ≈ 14 g H₂

Since the data was given to two significant figures, we must round our answer to two significant figures as well.

The difference between the outer covering of plants and animals is that plant cell has cellulose cell wall while animal cell is surrounded by a cell membrane

<h3>What is a cell?</h3>

A cell is the structural and functional unit of an organism which is capable of existing alone as it contains organelles that perform specific functions.

The plant cell is covered by a rigid cell wall which contains cellulose as its outer covering.

The animal cell contains not cellulose cell wall at its out covering but instead it is covered by a cell membrane.

Therefore, the difference between the outer covering of plants and animals is that plant cell has cellulose cell wall while animal cell is surrounded by a cell membrane.
