Answer: Option (D)
Explanation: In order to form coal, two processes might be undergone and they are as follows-
Thus the correct answer is option (D).
Answer:
6.460 gm is the correct answer .
Explanation:
Given
Kate’s blood volume=
blood glucose=
As we know that
The includes the blood glucose of the
So of the Kate’s blood volume can be determined by
To convert into the gm we have divided by the 1000
Therefore the glucose in her blood=
Answer and explanation:
The nuclides with the same atomic number, but different mass numbers are isotopes.
So, in this case, each species will have the same atomic number and a different mass number, that will be the same that it is written in the name of the element:
Answer:
a) IUPAC Names:
1) (<em>trans</em>)-but-2-ene
2) (<em>cis</em>)-but-2-ene
3) but-1-ene
b) Balance Equation:
C₄H₁₀O + H₃PO₄ → C₄H₈ + H₂O + H₃PO₄
As H₃PO₄ is catalyst and remains unchanged so we can also write as,
C₄H₁₀O → C₄H₈ + H₂O
c) Rule:
When more than one alkene products are possible then the one thermodynamically stable is favored. Thermodynamically more substituted alkenes are stable. Furthermore, trans alkenes are more stable than cis alkenes. Hence, in our case the major product is trans alkene followed by cis. The minor alkene is the 1-butene as it is less substituted.
d) C is not Geometrical Isomer:
For any alkene to demonstrate geometrical isomerism it is important that there must be two different geminal substituents attached to both carbon atoms. In 1-butene one carbon has same geminal substituents (i.e H atoms). Hence, it can not give geometrical isomers.
Answer:- cell potential = -0.19 volts
Solution:- The equation that shows the connection between and cell potential, E is written as:
in this equation, n stands for moles of electrons, E stands for cell potential and F stands for faraday constant and it's value is .
It asks to calculate the value of E, so let's rearrange the equation:
Let's plug in the values in it:
since,
Where C stands for coulombs and V stands for volts.
So,
E = -0.19 V
So, the cell potential is -0.19 volts.
