Write equations for the half-reactions that occur at the anode and cathode for the electrolysis of each aqueous solution: a. Ni(NO3)2(aq) b. KCl(aq) c. CuBr2(aq)
Step 1 of 3
Chapter 1 The Chemical World Chemists use the scientific method to understand the world. Key characteristics of the scientific method: 1. Make observations. Observations – involve the measurement or description of some aspect of nature Antoine Lavoisier (1743–1794), a French chemist, made an observation about the physical world. He named the elements carbon, hydrogen and oxygen; discovered oxygen’s role in combustion and respiration. Lavoisier burned substances in closed containers. He measured the mass of each container and its contents before and after burning the substance inside. 1) Make observations observations rely on the use of sensitive instrumentation 2) Formulate hypotheses. Hypothesis – a tentative interpretation or explanation of the observation
