Write an equation for the following single-replacement reactions.?
Write an equation for the following single-replacement reactions: Express ans. as a chem. equa. Identify all phases and enter noreaction if there is no reaction. A) Silver wire is put into a nickel nitrate solution. B) Nickel wire is put into a silver nitrate solution. Write a balanced equation for each of these single-replacement reactions. Express as chem. equation with all phases in ans. If "no reaction" write no reaction. C) Zinc is added to a lead(II) sulfate solution. D) Lead is added to a zinc sulfate solution. For double-replacement reactions: E) Aqueous solutions of chromium (III) chloride and lithium hydroxide react to give a chromium (III) hydroxide precipitate and aqueous lithium chloride. F) Aqueous solutions of cobalt(II) sulfate and mercury (I) nitrate react to give a mercury (I) sulfate precipitate and aqueous cobalt (II) nitrate. Complete and balance for Neutralization reactions: G) HNO2(aq) + Ra(OH)2(aq)-------> H) H2SO3(aq) + CsOH(aq)------> Thank You to the person who can help me figure these out!
When will a double replacement equation result in no reaction?
The question wording is kind of throwing my head for a loop. Do you mean: when will AB + CD ≠ AD + CB ? First things first, you need to check what you are doing. When two compounds react and their products are both soluble (aq) then they would break apart in the water. If you have to write a net ionic equation for the reaction, you would end up crossing everything out because they are all just separate ions floating around. This is an example of when AB wouldn't react with CD. However, both of the reactants must be aqueous. Example AB(aq) + CD(aq) ----> AD(aq) + CB(s) ----either AD or CB can be a precipitate (doesn't need to be a solid). Side note, these are not reversible reactions (this is easily understood by picturing yourself taking out a few ions in the net ionic eq).Like most things in chemistry, the reaction has to be thermodynamically favorably in order to happen. Meaning, if this reaction happens, will energy be released? This doesn't mean that is always the answer though. No. Chemistry is too clever for an easy answer. Sometime a reaction can occur just because it would make things less orderly. Entropy is seen everyday. Why does water evaporate even though it has to absorb energy to do so? because of entropy. ΔSsys > 0. This is also true for a lot of solutes (Ammonium nitrate). Imagine that you own a professional sports team and another team preposes a trade. In order for you to accept the trade, it needs to be beneficial for your team and/or to your community. The same is true for a chemical reaction. Gibbs free energy equation is helpful for thermodynamics of a reaction: ΔG=ΔH−TΔS (dG is the change is free energy, dH is the change in enthalpy, T is temp, and dS is the change in entropy. Look for a negative dG for a spontaneous reaction)(Keq can also affect the dG, but that is going beyond the question at hand and can make the math more complicated)Anyways, hope this helps! steps: 1)check solubility rules 2)check thermodynamics if necessary
