Because of its toxicity, arsenic is the active ingredient in many pesticides. It doesn't just show you the answer but also shows you step by step instructions on how to solve and if one step isn't making sense you can tap on it and it expands and give a more in depth explanation on how exactly they got to that step. Note that sodium carbonate is also a product, one that was not mentioned in the problem text. Hence, it is written in molecular form. Mixing the two solutions initially gives an aqueous solution that contains Ba2+, Cl, Li+, and SO42 ions. Ammonium acetate and potassium sulfide balanced equation - Ammonium acetate and potassium sulfide balanced equation is a mathematical instrument that assists . So, this is a more chemically correct net ionic: The problem is that your teacher (or an answer in an online chemistry class) might expect the first net ionic I wrote above. Nothing could be further from the truth: an infinite number of chemical reactions is possible, and neither you nor anyone else could possibly memorize them all. Q: write and balance: When aqueous iron (III) sulfate is mixed with aqueous magnesium hydroxide, iron. The possible products of an exchange reaction are rubidium chloride and cobalt(II) hydroxide): B According to Table 4.2.2, RbCl is soluble (rules 1 and 4), but Co(OH)2 is not soluble (rule 5). While chemical equations show the identities of the reactants and the products and gave the stoichiometries of the reactions, but they told us very little about what was occurring in solution. {
