One piece of silver jewelry, at T1= 985.8°C, has three times the mass of another piece (3m1= m2) at TI= 120.0 °C. Both are placed in a calorimeter of negligible heat capacity. What is the final temperature inside the calorimeter (C = 0.233 J/g°C)?
-Isotopes are represented by the symbol , where Z is the atomic number, A is the mass number, and E is the elemental symbol. . Write symbol that represents an isotope of nickel that contains 28 protons and 32 neutrons in the nucleus. Isotopes are also represented by the notation: Name-A, where Name is the name of the of the isotope. An example of this isotope notation is magnesium-26. This represents an isotope of The extremely small size of atoms...
