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:
Explanation:
Here we want to find the largest area of a circle that can be made from a piece of thread 25.2 cm long, assume no knot
.
This means that the circumference of the circle must equal to the length of the thread, so we can write:
L = 25.2 cm
And the circumference can be written as:
where
r is the radius of the circle
Solving for r, we find the radius:
The area of a circle is given by the formula
So in this case, we find:
The name of the acid is Bromous acid and the Formula of the acid is HBrO₂.
<h3>What is Acids ? </h3>
Acids is defined as substances that is able to donate a proton or hydrogen ion to other substance. Acids acts as proton donor.
<h3>What is Oxoacids ? </h3>
An oxoacids is an acids that contains oxygen. It is also called oxyacids or ternary acids. Oxoacids are the acids of oxoanions.
If anion name contains the suffix ‘ate’ then replace ‘ate’ with ‘ic’.
If anion name contains the suffix ‘ite’ then replace ‘ite’ with ‘ous’.
Given anion is bromite. Formula of bromite is BrO₂⁻. It is an oxoanion.
Now write the name of acid. Here anion name contains the suffix ite so replace the ‘ite’ of bromite with ‘ous’.
The name of the acid is Bromous acid.
Formula of the acid is HBrO₂.
Thus from the above conclusion we can say that The name of the acid is Bromous acid and the Formula of the acid is HBrO₂.

Redox reaction has a great economic impact. many product that we use in our daily lives are made using redox reaction. some of which are electroplating, that we use in our watches. and redox reaction also caused the rusting of irons, so buildings will rust and become brittle
