The correct answer is C. 436 kJ are required to break one H-H bond.<br /><br />Explanation:<br />The average bond energy of the single covalent bond in H2 is 436 kJ/mol. This means that 436 kJ of energy is required to break one H-H bond.<br /><br />Option A is incorrect because it states that 436 kJ are required to break all of the chemical bonds in 1 mol H2. This is not true because there is only one H-H bond in 1 mol H2.<br /><br />Option B is incorrect because it states that 435 kJ are released when all of the chemical bonds in 1 mol H2 are broken. This is not true because the bond energy is 436 kJ/mol, not 435 kJ/mol.<br /><br />Option D is incorrect because it states that 436 kJ are released when one H-H bond forms. This is not true because bond formation releases energy, not requires it.<br /><br />Therefore, the correct answer is C. 436 kJ are required to break one H-H bond.
