1. Define the law of conservation of mass.

Juan freezes a bottle of water to ice (500. ml) in preparation for a road trip. how much heat can be absorbed by that ice before it is fully melted?

Predict which atom has a higher ionization energy. CL or I

Let's say we have 2 Zinc atoms and 2 Sulfur atoms on one side of the equation. According to the Law of Conversation and Mass, how many Zinc Sulfide molecules would be on the other side of the equation?

Consider the balanced chemical reaction below and determine the percent yield for carbon dioxide if 37.4 moles of iron (IIl) oxide yielded 66.8 moles of carbon dioxide

Now consider the decomposition of dinitrogen monoxide. N2O (g) → N2 (g) + ½ O2 (g) rate = k[N2O]2 Starting with an initial concentration of 1.0 M, what is the half-life of the reaction?
