根据金属与稀酸的反应的化学方程式,我们可以求出各种金属与足量的稀酸反应产生等量(2份质量)的氢气所需的质量,并且在数轴上找出它们各自的位置,表示如图:
Based on the chemical equation for the reaction of the metal with the dilute acid we can find the mass required for the reaction of the various metals with a sufficient amount of dilute acid to produce equal amounts (2 parts by mass) of hydrogen and find their respective positions on the axes , Said as shown:
