Answer:
The energy need to break this 0=0 bond is 495 kJ/mol
Explanation:
Step 1: Data given
oxygen molecule = O2
In an O2 molecule, the 2 O-atoms are held together by a double bond with a bond energy of 495 kJ/mol.
To break this chemical bound, it requires energy
2O(g) → O2(g)
The bound energy of a double oxygen bound = 495 kJ/mol
Since we have 1 molecule (consisting in 2 O atoms)
The energy need to break this 0=0 bond is 495 kJ/mol
the first option; waning gibbous + decreases
Answer:
Thermal energy transfer involves the transfer of internal energy. The three types of thermal energy transfer are conduction, convection and radiation. ... Those are both good examples of convection, the movement of warm particles from warmer to cooler locations, Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas. Radiation is the transfer of thermal energy through thermal emission.
