250 kJ of energy are removed from a 4.00 x 10^2 g sample of water at 60°C. Will the sample of water completely freeze? Explain

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
