Question: Answer the following question given this paragraph: Technically, any redox reaction can be set up to make a voltaic cell. In modern society, however, only certain redox reactions are put to practical use. A portable voltaic cell that generates electricity to power devices for our convenience is called a battery. All batteries are based on redox reactions. The first battery (called a "voltaic pile") was constructed by the Italian scientist Alessandro Volta in 1800 and was based on the copper/zinc reaction depicted in - ball-ch14_s03_f01. Unfortunately, it was messy, requiring quantities of copper and zinc salts dissolved in water. In 1866, the French scientist Georges Leclanche invented the dry cell, a precursor to today's modern battery. A schematic of a dry cell is shown in - ball-ch14_s03_f02. The zinc case and the central carbon rod serve as the anode and cathode, respectively. The other reactants are combined into a moist paste that minimizes free liquid, so the battery is less messy (hence the name dry cell). The actual redox reaction is complex but can be represented by the following redox reaction: + 2+ Zn + 2MnO2 + 2NH4 Zn + Mn2O3 + 2NH3 + H2O A dry cell has a voltage of about 1.56 V. While common and useful, dry cells have relatively short lifetimes and contain acidic components. They also cannot be recharged, so they are one-use only. Batteries that can be used only once are calledprimary batteries. Figure 14.2 Dry Cells. Q: Technically, any redox reaction can be set up to make a what? Choices: - Black Cell - blocky cell - skaht cell - voltaic cell A:
Answer:
voltaic cell
