(negative pole) zinc tablet dissolved. There's copper on the brass, and it's got more quality. The electronics flow from zinc to copper by a steering line. Cuso4 experimental explore: zn + cu 2+ = zn 2+ + cu? What's the difference between the two poles? What? (d) rare h2so4 zn cu, the device cannot form a closed loop or form an original battery. Experimental exploration: the conditions and principles for the formation of the original battery (1) have two different active metals (or metals and non-metals) to be electrodes; negative poles: the one pole of the active metal; occurrence of the oxidation reaction positive: the one pole of the inactive metal or non-metal; occurrence of the reduction reaction of the two electrodes must be inserted into the electrolyte solution; electrodes have the ability to react to the oxidation of a component in the electrolyte solution (3) to form a closed circuit. The more dynamic metal has an oxidation reaction, the electrons flow from the more active metal (negative pole) to the less active metal or non-metallic (positive pole) original battery, which consists of the following conditions: (conductive wire connection or direct contact and electrolysed solution) spontaneous oxidation reaction: (direction or direct contact and electrolytic insertion of electrolyte solution); (c) primary battery; (c) electrode name and electrode reaction: negative positive extreme (or non-metal capable of conductivity); e) active metal; and (e) less active metal i. Determine the activity sequence of the three metals. The more lively metals have an oxidation reaction whereby electrons flow from more lively metals (negative poles) to less lively metals or non-metallic (positive poles) rare h2so4 (i) rare h2so4 (ii) rare h2so4 (iii) a b b c 0 0 0 0 0 0 0 0 0 0 0 0 c> b > a practice 2 a, b, c three metals, leaching a in cnitate, the surface of a is c deciphered, and b is the negative pole of b batteries when a and b form their original batteries. Determine the activity sequence of the three metals. The more dynamic metals have an oxidation reaction, the electronics move from the more active metals (negative poles) to the less active metals (positive poles) b > a > c to the more active metals, and the electronics move from the more active metals (negative poles) to the less active metals (negative poles) to the less active metals or non-irradiated metals (positive poles) in the original batteries, where the oxidation and reduction reactions are not carried out at the same location, without mutual resistance, and at a much faster rate than when the original batteries are not formed. Thinking about the following methods that do not speed up the reaction rate of zinc particles and rare sulfuric acid: cuso4 na2so4 more lively metals are oxidized, electrons are moving from more active metals (negative poles) to less active metals or non-metallic (proper poles) capable of forming micro-luminous batteries capable of forming micro-luminous batteries capable of increasing temperatures and increasing the rate of reaction, not capable of being in the devices shown in the left chart, and the original batteries are not the justifications? It is the original battery that indicates the electronic flow and determines the positive and negative pole. It's the original battery that writes the electrode reaction, the total reaction. Case 1
