The energy source from a reservoir would provide affordable, abundant electricity for a factory is a hydroelectric power plant; option D.
<h3>What is energy?</h3>
Energy is the ability to do work.
Energy generating plants may either use wind, water or solar energy to produce electrical energy.
The most abundant source of energy from a reservoir is hydroelectric power plant.
Therefore, the energy source from a reservoir would provide affordable, abundant electricity for a factory is a hydroelectric power plant.
In conclusion, hydroelectric power plants are reservoirs of abundant energy supply.

Answer:
The rate of disappearance of C₂H₆O = 2.46 mol/min
Explanation:
The equation of the reaction is given below:
2 K₂Cr₂O₇ + 8 H₂SO₄ + 3 C₂H₆O → 2 Cr₂(SO₄)₃ + 2 K₂SO₄ + 11 H₂O
From the equation of the reaction, 3 moles of C₂H₆O is used when 2 moles of Cr₂(SO₄)₃ are produced, therefore, the mole ratio of C₂H₆O to Cr₂(SO₄)₃ is 3:2.
The rate of appearance of Cr₂(SO₄)₃ in that particular moment is given 1.64 mol/min. This would than means that C₂H₆O must be used up at a rate which is approximately equal to their mole ratios. Thus, the rate of of the disappearance of C₂H₆O can be calculated from the mole ratio of Cr₂(SO₄)₃ and C₂H₆O.
Rate of disappearance of C₂H₆O = 1.64 mol/min of Cr₂(SO₄)₃ * 3 moles of C₂H₆O / 2 moles of Cr₂(SO₄)₃
Rate of disappearance of C₂H₆O = 2.46 mol/min of C₂H₆O
Therefore, the rate of disappearance of C₂H₆O = 2.46 mol/min
When a solid (solute) comes in contact with the liquid (solvent), the solute goes about C) dissolution, in which the solid dissolves into the liquid.

The semi will have the hardest time changing direction because of its mass. The more mass there is, the more effort it takes to accelerate and decelerate as well as change direction.
The correct answer among the choices given is option C. A bond that is not symmetrical along the axis between two atomic nuclei is a pi bond. These bonds are covalent bonds where one atomic orbital overlap to the other atomic orbitals.
