    Chemical reactions
    Are the products of calcium + water --- calcium hydroxide + hydrogen gas and is that expressed as CaOH + H2O ----(arrow) CaOH + H2

    Are the products of tin + antimony(V)chloride----tin chloride + antimony
    And is that expressed as Sn + AtCl5-----(arrow) SnCl5 + At

    Don't type homework problems. Against site rules. Try to work it out, post what you got, and then people are willing to help you with it.

    Calcium hydroxide is and not . Calcium does react with water to form calcium hydroxide and hydrogen:



    Antimony is Sb, not At (astatine).

    I think the reaction you want is

    I didn't look up the chemical potentials of tin and antimony, but I think that tin will replace antimony as shown. The pentachlorides aren't that common. The trichlorides are more common and more stable.

    Don't tag onto the end of another question/answer, even if the questions are similar. In the future, post each question or group of questions in its/their own thread.

    What I've written is the ionization of both species. It would stay like that (a mixture of ions) unless something drives the reaction to the right. Something that might drive the reaction to the right would be that something was removed from the solution. For example, something might precipitate. If you combine the anions with the cations, will anything precipitate? (Use your solubility rules to figure that out). Another thing that might drive the reaction to the right would be something that decomposes. If something decomposed to produce a gas, and that gas bubbled out of the solution, that would drive the reaction to the right. Again, combine the anions with the cations. Will any of those compounds decompose to produce a gas? (Hint: yes).
