Answer:

Explanation:

2 sheets of plywood will be needed.

Step-by-step explanation:

See the attached diagram.

Each three square plywood has area 1 units by 3 units = 4 feet by 12 feet = 48 feet square.  {Since each unit on the coordinate plane represents four feet}

Now, the two triangular plywood has area half of a unit square area.

So, two triangular plywood has total area = 1 unit by 1 unit = 4 feet by 4 feet = 16 feet square.

Therefore, the total area of plywood required to make the triangular prism is (48 + 16) = 64 feet square.

Now, if a sheet of plywood measures 4 ft by 8 ft i.e. 32 feet square, then the carpenter will need such sheets of plywood. (Answer)

The type of reaction present in the equation(2Mgl + Mn(SO₃)₂ → 2MgSO₃ + Mnl₄)  is a double displacement reaction.

2Mgl + Mn(SO₃)₂ → 2MgSO₃ + Mnl₄

The reactant of the reaction is on the left side while the product of the reaction is on the right side.

Double displacement is a kind of reaction in which the two reacting compounds exchange their radicals or ions to form two new compounds. The anions and cations of the two different molecules switch places to form a new compound.

The reaction type is a double displacement reaction because the cations (mg and mn) and anions(so₃²⁻ and l⁻) switch positions.

The chemical reaction that will occur spontaneously is given by this chemical equation: Mg²⁺ + V²⁺ ----> Mg + V.

Reduction can be defined as a half-reaction through which the number of electrons (oxidation states) that is associated with the atoms of a chemical element are changed i.e reduced or decreased.

Based on the chemical reactions with the standard electrode reduction potentials, the half cell (Cu²⁺) with the higher reduction potential (+0.15) will be reduced while the half cell (V²⁺) with a lower oxidation potential (-1.18) will be oxidized and as such the chemical equation is given by:
