Answer:
See explanation
Explanation:
Substitution implies that one thing is repalced by the other.
Substitution of one ion by another largely depends on the sizes of the ions in question.
The ionic radius of Mn3+ is about 0.65 Angstroms while that of In3+ is about 0.94 Angstroms. On the other hand, the ionic radius of Y3+ is about 1.032 Angstroms.
It is clear that the sizes of Mn3+ and In3+ are closer to each other hence Mn3+ can substitute for In3+ easily than Y3+ in a lattice site.
The larger size of Y3+ explains why it is not easily replaced by Mn3+.
Answer:
The limiting reactant is salicylic acid.
Explanation:
From the equation of reaction,
1 mole of acetic anhydride (C4H6O3) (102g) reacts with 2 moles of salicylic acid (C7H6O3) (276 g)
80 g of acetic anhydride would react with (80×276/102) = 216.5 g of salicylic acid
216.5 grams of salicylic acid that is required to react with 80 grams of acetic anhydride.
The available mass of salicylic acid is 70 grams which makes salicylic acid the limiting reactant.
