When bonds are formed, energy is released. in a water molecule, the two hydrogens are both bonded by single bonds to the central oxygen atom. the bond energy associated with an o–h bond is 463 kj/mol. again, using the balanced chemical equation shown above, how much energy is released in forming the o–h bonds?

The balanced chemical equation is:

2H2 + O2 → 2H2O

Based on the reaction stoichiometry:

2 moles of water are formed.

Each water molecule has 2 O-H. Thus, a total of 4 O-H bonds are formed.

Energy released/O-H bond = 463 kJ/mol

For 4 O-H bonds this would be= 4 * 463 = 1852 kJ

Ans: Thus, -1852 kJ (negative sign indicates that energy is released) in the forming of O-H bonds.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

fe 55.85 g/mol and h2o 18.02 g/mol.
