A scientist measures the standard enthalpy change for this reaction to be - 758.0 kJ/mol: 2NO(g) + 2 H2(g) –N2(g) + 2 H2O(1) Based on this value and the standard formation enthalpies for the other substances, the standard formation enthalpy of NO(g) is kJ/mol.​

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
