Question at position 10 In the laboratory, qualitative analyses of different ions in water sources can be determined with precipitation reactions. For example, Ag+ ions are soluble in water containing NO3- counterions, but readily precipitate out of solution when NaCl is added. This is because AgCl has a low solubility in water. For the silver precipitation reaction above, the precipitate represents the Question Blank 1 of 1[input].简答题

REACTION:  aqueous potassium nitrate is placed in a beaker containing aqueous sodium acetate Write the balanced chemical reaction by completing the table below. For each of the product, determine what the product will be and place it in the appropriate blank. For example, for the reaction of strontium chloride and sodium iodide, for the "strontium product," type in the formula of the product that contains Sr. Likewise, for "sodium product," type in the formula of the product that contains Na. Please remember to: Write the correct coefficients for all reactants and products. Write the correct states for all reactants and products. (Remember: Do not write 1's in balanced equations.) Write NO RXN for each product if a reaction does NOT occur. DO NOT worry about formatting subscripts. Thus, if two moles of aqueous strontium hydroxide, please type it as 2 Sr(OH)2(aq). DO NOT space between the formula and the state of the compound, such as: 2 Sr(OH)2(aq). DO add a space between the coefficient and the formula, such as: 2 Sr(OH)2(aq). For the "Description", type one of the following and DO NOT capitalize:   precipitation neutralization gas evolution single displacement combustion combination decomposition  NO RXN   [Fill in the blank] + [Fill in the blank] ⟶\longrightarrow [Fill in the blank] + [Fill in the blank] potassium reactant + sodium reactant  ⟶\longrightarrow acetate product + nitrate product Description for this type of reactions:  [Fill in the blank]

REACTION:  aqueous barium chloride is placed in a beaker containing aqueous sodium sulfate反应：将水溶液氯化钡放入含有水硫酸钠的烧杯中 Write the balanced chemical reaction by completing the table below. For each of the product, determine what the product will be and place it in the appropriate blank. For example, for the reaction of strontium chloride and sodium iodide, for the "strontium product," type in the formula of the product that contains Sr. Likewise, for "sodium product," type in the formula of the product that contains Na.通过完成下面的表格来写出平衡的化学反应。对于每个产品，确定产品是什么，并将其放入相应的空格中。例如，对于氯化锶和碘化钠的反应，对于“锶产物”，在含有鍶的产物的公式中输入。同样，对于“钠产物”，在含有 Na 的产物的公式中输入。 Please remember to:  请记得： Write the correct coefficients for all reactants and products.为所有反应物和产物写出正确的系数。 Write the correct states for all reactants and products. (Remember: Do not write 1's in balanced equations.) 为所有反应物和产物写出正确的状态。（记住：不要在平衡方程中写1。） Write NO RXN for each product if a reaction does NOT occur.如果没有反应发生，则对每个产物写作无 RXN。 DO NOT worry about formatting subscripts. Thus, if two moles of aqueous strontium hydroxide, please type it as 2 Sr(OH)2(aq).别担心下标格式。因此，如果有两摩尔水溶性氢氧化锶，请将其标注为 2 Sr（OH）2（aq）。 DO NOT a space between the formula and the state of the compound, such as: 2 Sr(OH)2(aq).不要在公式和化合物状态之间 留空格 ，比如：2 Sr（OH）2（aq）。 DO add a space between the coefficient and the formula, such as: 2 Sr(OH)2(aq).在系数与公式之间加一个空格，例如：2 Sr（OH）2（aq）。 For the "Description", type one of the following and DO NOT capitalize:  对于“描述”，请输入以下其中之一， 且请勿大写：   precipitation  降水 neutralization  中和 gas evolution  气体演化 single displacement  单排量 combustion  燃烧 combination  组合 decomposition  分解 NO RXN  无处方   [Fill in the blank] + [Fill in the blank] ⟶\longrightarrow [Fill in the blank] + [Fill in the blank] aqueous barium iodide  水溶液碘化钡 + aqueous potassium sulfate水溶液硫酸钾 ⟶\longrightarrow barium product  钡产品 + potassium product  钾产物 Description for this type of reactions:  这类反应的描述：[Fill in the blank]
