Answer:
a. Zinc is the limiting reactant.
b.
c.
Explanation:
Hello there!
a. In this case, when zinc metal reacts with bromine, the following chemical reaction takes place:
Thus, since zinc and bromine react in a 1:1 mole ratio, we can compute their reacting moles to identify the limiting reactant:
Thus, since zinc has the fewest moles we infer it is the limiting reactant.
b. Here, we compute the grams of zinc bromide via both reactants:
That is why zinc is the limiting reactant, as it yields the fewest moles of zinc bromide product.
c. Here, since just 0.722 mol of bromine would react, we compute the corresponding mass:
Thus, the leftover of bromine is:

Answer :
(A) The balanced chemical reaction will be:
This reaction is a single replacement reaction.
(B) The balanced chemical reaction will be:
This reaction is a double displacement reaction.
(C) The balanced chemical reaction will be:
This reaction is a combination reaction.
Explanation :
Balanced chemical reaction : It is defined as the reaction in which the number of atoms of an element present on reactant side must be equal to the product side.
Part (A):
The balanced chemical reaction will be:
This reaction is a single replacement reaction in which the most reactive element displaces the least reactive element from its solution.
Part (B):
The balanced chemical reaction will be:
This reaction is a double displacement reaction in which a positive cation and a negative anion of two reactants exchange their places to form two new products.
Part (C):
The balanced chemical reaction will be:
This reaction is a combination reaction in which the two atoms combine to form a larger molecule.
