Answer:
1 mole of calcium contains 6.023 
atoms.
Explanation:
1 mole is the amount of a substance that contains exactly 
constituent particles. 1 mole of a substance is always equal to the atomic mass of the element.

Answer:
Reactants have more energy than products
Explanation:
Generally, in an exothermic reaction heat is released. In other words, energy is released. So you start with reactants which have a set amount of stored chemical energy, and you lose some in the reaction. Since energy is 'leaving', the stored chemical energy in the products is less than what we started with in the reactants. When given a graph, you can tell this is true because going from left to right, the line representing the stored chemical energy will start at a higher level than where it ends.
Answer:
true
Explanation: becuase if you add the same liquid to a small container and then add it to a big container its going to have the same liquid amount it started with
