How could a solution of copper chloride and water be separated into its starting substances?
The copper chloride solution can be separated into its starting substances by a process called electrolysis. During electrolysis, an electric current is passed through the solution, causing the copper ions to be reduced at the cathode to form copper metal, and the chloride ions to be oxidized at the anode to form chlorine gas and water. This results in the separation of copper and chloride ions.
How could you make a pure sample of solid silver chloride starting with silver nitrate solution?
Add hydrochloric acid to silver nitrate and stir well to ensure it is all reacted. Silver chloride will precipitate out and is fairly insoluble. Filter the solution and collect the filtrate on the filter paper. Rinse a few times with water to wash off the excess acid. Dry the filtrate in the oven. The result is pure silver chloride. Note this is sensitive to UV light, so this is best done in a dark room under a red lamp.
What are the substances you start with in a chemical reaction called?
The substances you start with in a chemical reaction are called reactants. Reactants are the starting materials that undergo changes to form new substances called products.
What 2 substances will be formed when hydrochloric acid reacts with sodium hydroxide?
HCl + NaOH = H2O + NaCl Or, water and table salt--which will dissolve in water. Benzoic acid, C6H5COOH, will not be formed; neither of the two starting chemicals contains carbon, and benzoic acid contains a lot of it. - - - - - Benzoic acid and sodium chloride
What is involved in a chemical reaction?
Chemical ReactionA chemical reaction is composed of REACTANTS and PRODUCTS. The starting compounds and/or elements in the reaction are known as reactants. Once they are combined, the resulting elements/compounds are called the products. Basically:Reactant ---> ProductOr:Reactant 1 + Reactant 2 ---> Product 1 + Product 2Example:Magnesium Chloride + Lithium Floride ----> Lithium Choride + Magnesium FluorideMgCl2 + LiF = LiCl + MgF2

How could solution of magnesium sulfate and water be separated into its starting substances?
It is like that because of love and god
How can a solution be separated into its starting substances?
Distillation is the process used to separate solutions into constituent components. For example if we have a solution of salty water, we can evaporate or boil away the water, leaving behind the salt.
How could a substance of copper chloride and water be separated into its starting substance?
One way in which it can be separated is by letting the water evaporate, leaving the copper chloride behind.
How could a solution of magnesium sulfate and water be separated into its starting substances?
The solution of magnesium sulfate and water can be separated by a process called evaporation. The solution is heated until the water evaporates, leaving behind the solid magnesium sulfate. The remaining magnesium sulfate crystals can then be collected and the water can be condensed back into a liquid form through condensation.

What a substances in a chemical reaction that are combined or separated to form new substances?
The substances in a chemical reaction that are combined are the reactants, and the substances that are formed as a result of the reaction are the products. Reactants are the starting materials, while products are the final end-products. Chemical reactions involve the breaking and forming of chemical bonds between atoms.
Is salt an element or a compound or a homogeneous mixture or a heterogeneous mixture?
In fact, salt water is a solution because salt dissolves in water. A mixture is a mix of substances that can be separated by physical means. Saltwater can be separated by boiling away the water and leaving the salt behind, but because the salt dissolves in water, it is a solution. There are two parts to a solution. The solute and the solvent. The solute is the substance that is dissolved in the solvent. The solute is usually smaller than the solvent. A compound is a substance in which two or more atoms are joined in a chemical reaction. The resalting substance has properties different than those of the starting substances.
The starting substances that are evoled in a chemical reaction?
The substances evolved after a chemical reaction are called in English products and are not starting substances - the are called reactants.
When substances are different from the starting substances what occured?
This is a chemical reaction.
What are starting substances called?
Starting substances are called reactants in a chemical reaction. Reactants are the substances that are present at the beginning of a chemical reaction and undergo transformation into products.
When a chemical change occurs the atoms of each starting substances are only what?
The atoms are of each starting substances are only rearranged.
