NAMES. follow this please, Sodium + chromate = sodium chromate (not for reaction perposes) and the remaining is 3H2O which is trihydrate (has 3 water molecules). It can combine with a number of compounds to form hypochlorites, which may also be regarded as the salts of hypochlorous. Reasoning: It is made up of two oppositely charged species: a monoatomic metal cation, K+ (potassium ion), and a polyatomic anion, Cr2O7^2- (known as dichromate). *Response times vary by subject and question complexity. Good luck! Asterisks will match zero or more unspecified characters. Patterns are strings containing one or more asterisk (*) characters. That would be potassium dichromate. When two aqueous solutions of ionic compounds are mixed together, the resulting reaction may produce a solid precipitate. This guide will show how to use the solubility rules for inorganic compounds to predict whether or not the product will remain in solution or form a precipitate. Scientists or chemists identify a particular chemical compound from its scientific name. This is an an ionic (Metal and Non-Metal) compound. O has an ionic charge of -2, and thus there are two O atoms the total negative charge is -4. Name the following Ionic Compound: KCl. 1. Convert grams Na2CrO4 to moles or moles Na2CrO4 to grams. Common Names of Chemical Compounds. The molar mass of a substance, also often called molecular mass or molecular weight (although the definitions are not strictly identical, but it is only sensitive in very defined areas), is the weight of a defined amount of molecules of the substance (a mole) and is expressed in g/mol. 0.
