Consider this reaction: li3n(s) + 2 h2(g) → linh2(s) + 2 lih(s)a. how many grams of h2do we need to react with 1.5 g of li3n? consider this reaction: li3n(s) + 2 h2(g) → linh2(s) + 2 lih(s)

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.
