REACTION:  aqueous ammonium dichromate is placed in a test tube containing aqueous plumbic nitrate 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] aqueous ammonium reactant + aqueous plumbic reactant  ⟶\longrightarrow nitrate product + dichromate product Description for this type of reactions:  [Fill in the blank]
