Determine the final temperature of a mixture of 50 grams of water at 10 C added to 120 grams of water at 80 C. Show all work. Use the simulator to check your answer. (Hint: This is a weighted average.)

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
