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:
3
Explanation:
according according to me option b is correct
The correct answer is<span> C) Water takes long to heat and cool down than other liquids.
It doesn't climb up the sides of a tube any more than other solutions do, and being a universal solvent has nothing to do with radiators. It does however take a long time to heat and cool down since you don't have a 100+ celsius burner to heat it up in an instant.</span>
1-5 is theory and 6-10 is law
Avagadros law states that volume of gas is directly proportional to number of moles of gas at constant pressure and temperature.
where V -volume , n - number of moles
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
substituting these values in the equation
V = 44.8 L
answer is C. 44.8 L
