NO3- Net Ionic Equation The balanced net ionic equation includes only species that are involved in the reaction. It can be found by removing ions that occur on both the reactant and product side of the complete ionic equation. Mg(s) + Zn2+(aq) = Mg2+(aq) + Zn(s) ...
Step 3: Verify that the equation is balanced Since there are an equal number of atoms of each element on both sides, the equation is balanced. 2NaNO3+ ZnO = Zn(NO3)2+ Na2O NaNO3+ZnO = Zn(NO3)2+Na2O ReactantsProducts Na12❌ ...
而可溶性氯化物与硝酸镁不能形成沉淀即不满足复分解反应发生条件而不能反应;故C不能一步实现;D、硝酸钡与硫酸或可溶性硫酸盐反应都可生成硫酸钡,该转化一步反应即可完成;故D能一步实现;故选AC.
D、当锌粉不足,只能与部分硝酸银反应时,滤纸上有Ag,滤液中有AgNO3、Cu(NO3)2、Zn(NO3)2、Mg(NO3)2,故D正确. 故选:C. 点评本题考查了金属活动性顺序的应用,完成此题,可以依据金属活动性顺序的意义进行. 练习册系列答案 1加1阅读好卷系列答案

【题目】分别将一定量的锌粉加入一定量的Mg(NO3)2、和Cu(NO3)2、AgNO3混合溶液中,充分反应后过滤。向所得固体上滴加盐酸有气泡产生。 (1)若向所得固体上滴加盐酸有气泡产生,则该固体含有金属为___。 (2)写出有关的化学反应方程式___(一个即可)。 (3)猜想...
While Cu, Ni and Mg nitrates behave similarly, the Zn salt shows some differences which possibly are due to a change of the coordination number with increasing salt content.doi:10.1515/zna-1998-1210A. GalstianM. StockhausenVerlag der Zeitschrift für Naturforschung...
3D Zn/Cu复合催化剂的制备:首先,将 0.27 mg/cm2 的纳米铜墨水(Zn/Cu 和 Nafion 催化剂混合物干燥后的加权装载量)喷洒到 3 × 3 cm2 的疏水性碳纸上。在空气中干燥后,以喷涂过的碳纸为工作电极,在 5 mM Zn(NO3)2 水溶液中进一步沉积锌,在 1 mA cm-2 下持续 100 秒。
(1)加入一定量的锌粉后,一定发生的反应的化学方程式为:Zn+2AgNO3=2Ag+Zn(NO3)2. (2)反应后滤液中一定含有的溶质是 Mg(NO3)2、Zn(NO3)2. 故答案为:(1)Zn+2AgNO3=2Ag+Zn(NO3)2;(2)Mg(NO3)2、Zn(NO3)2. 点评本题有一定难度,熟练掌握金属的化学性质、金属活动性顺序并能灵活运用是正确解答本题...
