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

Answer: Sustainable living
Explanation: It is a lifestyle by which an individual uses natural resources only as much as is necessary, which means in limited quantities, and thus reduces the general enormous exploitation of these resources. In this way, the needs of the individual are met and resources are put to use for generations to come. It also refers to personal resources as well as Earth resources in general.
It is obvious from today's point of view that if food was produced only as much as needed, it would mean not throwing away food, everyone, both those who could otherwise afford food and those who are now starving, would be fed up.
With the reduction of production not only of food but also of other necessities, that is, with production to meet the needs and not beyond, there would be less pollution and less emission of harmful hags and greenhouse effect.
Jeez this is middle school really. covalently bond
