A reaction was found to be spontaneous at temperatures above 1500 K, and nonspontaneous below 1500 K. If its enthalpy is +852 kJ/mol, what is its entropy?​

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom

What’s the question
