Answer:
2 Al + 6 HCl ⇒ 2 AlCl₃ + 3 H₂
Based on the stoichiometry of the reaction, 156.114 g of CuNO3 are required to produce 88.0 grams of aluminum nitrate, Al(NO3)3.
<h3>What is stoichiometry of a reaction?</h3>
The stoichiometry of a reaction is the molar ratio in which reactants combine to form products.
The stoichiometry of the reaction shows that 6 moles of copper (i) nitrate produces 2 moles of aluminium nitrate.
molar mass of Copper(I) nitrate, CuNO3 = 126 g
molar mass of aluminum nitrate, Al(NO3)3 = 213 g
88.0 g of aluminum nitrate, Al(NO3)3 = 88.0/213 moles = 0.413 moles
0.413 moles of Al(NO3)3 will be produced by 0.413 ×6/3 = 1.239 moles of CuNO3
Mass of 1.239 moles of CuNO3 = 1.239 × 126 = 156.114 g of CuNO3
Therefore, 156.114 g of CuNO3 are required to produce 88.0 grams of aluminum nitrate, Al(NO3)3.

Therefore, 156.114 g of CuNO3
FeNi or NiFe is an acronym used to refer a family of iron alloys.
<h3>What is alloy?</h3>
An alloy is a mixture of chemical elements that contains at least one is a metal.
<h3>Alloy of iron</h3>
The alloy of iron-nickel can be abbreviated as FeNi, which implies iron-nickel.
where;
- Fe stands for iron
- Ni stands for Nickel
Thus, FeNi or NiFe is an acronym used to refer a family of iron alloys.

Assuming an ebullioscopic constant of 0.512 °C/m for the water, If you add 30.0g of salt to 3.75kg of water, the boiling-point elevation will be 0.140 °C and the boiling-point of the solution will be 100.14 °C.
<h3>What is the boiling-point elevation?</h3>
Boiling-point elevation describes the phenomenon that the boiling point of a liquid will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent.
- Step 1: Calculate the molality of the solution.
We will use the definition of molality.
b = mass solute / molar mass solute × kg solvent
b = 30.0 g / (58.44 g/mol) × 3.75 kg = 0.137 m
- Step 2: Calculate the boiling-point elevation.
We will use the following expression.
ΔT = Kb × m × i
ΔT = 0.512 °C/m × 0.137 m × 2 = 0.140 °C
where
- ΔT is the boiling-point elevation
- Kb is the ebullioscopic constant.
- b is the molality.
- i is the Van't Hoff factor (i = 2 for NaCl).
The normal boiling-point for water is 100 °C. The boiling-point of the solution will be:
100 °C + 0.140 °C = 100.14 °C
Assuming an ebullioscopic constant of 0.512 °C/m for the water, If you add 30.0g of salt to 3.75kg of water, the boiling-point elevation will be 0.140 °C and the boiling-point of the solution will be 100.14 °C.

<u>Answer</u>: Solid Cu
Since this is a <u>voltaic cell</u>:
<u>Copper</u> is the cathode, therefore having a positive charge.
<u>Zinc</u> is the anode, therefore having a negative charge.
(Also, I took the exam and it's correct; good luck everyone!)
