To know the total energy you must know that bond-breaking is endothermic (+) while bondbond-forming is exothermic (-). The bond energy of ethene is 602 kJ/mol. Since we break the ethene, that would be -602 kJ/mol.
For C-F: -602 + 552 = -50 kJ/mol
For C-Br: -602 + 280 = -322 kJ/mol
For C-I: -602 + 209 = -393 kJ/mol
<em>Since the most negative, hence exothermic, answer is C-I, the answer is C-I.</em>
Answer:
Explanation:
Using the expression,
Where,
is the activation energy
R is Gas constant having value = 8.314 J / K mol
So,
A . A person Jumping represents an unbalanced force.
<u>Explanation:</u>
If equal amount of force applied on any object from both the directions, then the object will not move and so the force is a balanced force.
If an unequal amount of force on an object from both sides then the object will move in the opposite direction of the maximum force applied, so it is called as an unbalanced force.
- When the force is unbalanced then its velocity will change, so options C and D are omitted.
- In Option B the vase is sitting on a table, just kept so there is no action of any unbalanced force.
- But a person jumping represents an unbalanced force, since the person do not jump with constant velocity and it will vary.
In petroleum geology, a trap is a geological structure affecting the reservoir rock and caprock of a petroleum system allowing the accumulation of hydrocarbons in a reservoir. Traps can be of two types: stratigraphic or structural.
