    The last one isn't true because atoms don't get created or destroyed in chemistry. The third is true for the same reason; you can;t change the mass of a given quantity of particles. The second isn't true because volume is dependant on pressure and temperature and as there is an energy change during a reaction, temperature changes. The first is true because it happens in neutralization reactions.
