There chemical reactions that can realise or absorb gas to the atmosphere. This means it is harder or impossible to measure it with normal weighing devices and normal taring equipment. As a principal in chemical reactions we have conservation of mass.
Electrons and protons because they are essentially always the same
Answer: B
Explanation:
The rate law is the mathematical equation that describes how reactant concentration changes as a function of time. A law such as "Rate = k*[A]*[B]" means that, for each liter-equivalent of the reactant(s) A, there are k liters of reactant B. The law also dictates the molarity (and thus partial pressure) for each component in solution.
