Sally and Jo are conducting an experiment where they add 3grams of FeCl3 and 2grams of NH4OH. Both of them did the experiment, but Sally did it in a sealed bag and Jo did it in an open beaker. Sally's final mass was 6grams and Jo's final mass was 4 grams. Who did the experiment correctly?

20 look at the clock and the data table below. based on the data and on your knowledge of potential and kinetic energy, what is the best conclusion you can make about potential and kinetic energy? the total amount of energy stays the same. the clock has the most potential energy at point b since it is moving the fastest. there is always more potential energy than kinetic energy. potential energy can never be 0, but you can have 0 kinetic energy.
