A2 + B2 → 2AB ΔH = -549 kJ The bond energy for A2 is half the amount of AB. The bond energy of B2 = 432 kJ/mol. What is the bond energy of A2?

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

i think it's c. i'm not sure but i think so.

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
