Answer: a) 
is the limiting reagent
b) 3.59 g
c) 11.6g
Explanation:
To calculate the moles :
According to stoichiometry :
a) 9 moles of require= 4 moles of 
Thus 0.15 moles of will require=
of 
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
b) As 9 moles of give = 8 moles of
Thus 0.15 moles of give =
of
Mass of 
c) As 9 moles of give = 3 moles of 
Thus 0.15 moles of give =
of
Mass of 
All metals in the periodic table form metallic bonds. This includes every element in the
periodic table except those in the non-metal group. So elements that are
Polyatomic nonmetal, Diatomic nonmetal, Noble gas are those who DON'T FORM.
Answer: Silver, Rhenium, Lithium, <span>Bismuth </span>will form metal bonds.
It's D, because it has a fixed volume but it can take the shape of the container it's in, so it's not a fixed shape.

Answer is: 127 grams <span>rams of metallic copper can be obtained.
</span>Balanced chemical reaction: 2Al + 3CuSO₄ → Al₂(SO₄)₃ + 3Cu.
m(Al) = 54.0 g.
n(Al) = m(Al) ÷ M(Al).
n(Al) = 54 g ÷ 27 g/mol.
n(Al) = 2 mol.
m(CuSO₄) = 319 g.
n(CuSO₄) = 319 g ÷ 159.6 g/mol.
n(CuSO₄) = 2 mol; limiting reactant.
From chemical reaction: n(CuSO₄) : n(Cu) = 3 : 3 (1 : 1).
n(Cu) = 2 mol.
n(Cu) = 2 mol · 63.55 g/mol.
n(Cu) = 127.1 g.
