During a reaction, H for reactants is -750 kJ/mol and H for products is 920 kJ/mol. Which statement is correct about the reaction and correctly compares the energy in bonds?

a

Explanation:

the ones are stronger and herder to break so it will take more energy to break them then when they are made

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
