Question

# 10/29/195 4% gui7666 1st attempt Part 1 (0.7 pt) See Periodic Table (a) What is the significance of the negative sign associated with this value? Choose one: O A. Energy is absorbed from the surroundings during the reaction. O B. Energy is destroyed during the reaction. O C. Energy is released into the surroundings during the reaction. O D. Energy is created during the reaction. (b) Why is the magnitude of this value so much larger than the heat of vaporization of water (AHvap - 41 kJ/mol)? Choose one: O A. More energy is needed to form attractive forces between water molecules than to break H-Hand O-O bonds and form H-O bonds. OB. More energy is needed to break attractive forces between water molecules than to break H-H and O-O bonds and form H-O bonds. < 09/11 >

Answer 1

for question b , all options are not provided.

When reaction is endothermic reaction, which means energy is being absorbed and sign of this type of Onergy in position a Endothermic DH= tve When weachon às exothermic reachon which means energy is being vielease to the swirounding and syn of this type of energy is negative Exothermic DH a-ve norbe destroved NOTE: Energy can't be created option & is correct answer.
