Sally is making a model of a magnesium atom with an atomic mass number of 24 for her chemistry class. she has foam balls for the protons, neutrons, and electrons. she has added 6 neutrons to her model so far. how many more neutrons does she need to add to complete her neutral atom of magnesium?

Consider the story you just read. all but one of the choices below indicate that something is living.

To find the enthalpy of a reaction in the lab, you measured the of the reactants and the change during the reaction.
