Cs(s)+H20(l)--->CsOH(aq)+H2(g) The first step in film processing is to enhance the black/white contrast by using a developer to increase the amount of black. Write the overall chemical equation, the complete ionic equation, and the net ionic equation for the reaction of aqueous silver fluoride with aqueous sodium phosphate to give solid silver phosphate and a solution of sodium fluoride. I'm showing only those species that are actually involved in the reaction. Therefore, we know that neither one nor four can be our answers, simply because we're looking at the same product, and already know that those two substances are soluble. So I know that NH4 plus is a spectator ion because it doesn't change as I go from left to right. Phenomena and Processes 1. It's atoms or molecules are bound close together as possible Which means the correct answer to the question is zero. Rearranged to put the cation first on the reactant side. Write all the soluble reactants and products in their dissociated form to give the complete ionic equation; then cancel species that appear on both sides of the complete ionic equation to give the net ionic equation. Table 4.2.2 Guidelines for Predicting the Solubility of Ionic Compounds in Water. Write the complete molecular, complete ionic and net ionic equations. That being said, thallium is a heavy metal (that's a hint about the solubility). Therefore it's not going to form a precipitate and it's not going to have any change between the left and the right side of the reaction. It turns out that ammonium dihydrogen phosphate is quite soluble, but, evidently, it does precipitate out when the solution is very acidic. Consider the reaction when aqueous solutions of potassium chloride and ammonium phosphate are combined. When ammonium is reacted with a base, ammonia is produced. Na+(aq) + HSO3-(aq) + H+(aq) + Br-(aq) ---> Na+(aq) + Br-(aq) + H2O() + SO2(g) determine the molecular formula of the compound. A double displacement reaction is one in which exchange of ions take place. Synthesis or direct combination reaction And when we say something doesn't change we have to look both at the formula, in this case our ammonium ion, and the phase is aqueous. Using the information in Table 4.2.2, predict what will happen in each case involving strong electrolytes. Ca2+(aq)+S2-(aq)-->CaS(g), Which pair of elements would be most likely to form an ionic compound?
