Tin(II) chloride - Wikipedia
Tin(II) chloride, also known as stannous chloride, is a white crystalline solid with the formula Sn Cl 2.It forms a stable dihydrate, but aqueous solutions tend to undergo hydrolysis, particularly if hot.SnCl 2 is widely used as a reducing agent (in acid solution), and in electrolytic baths for tin-plating..

7 Reasons to Drink Warm Salt Water Every Day
How refined table salt is made Unlike unrefined sea salt, table salt has been stripped of its naturally-occurring minerals during processing. To produce your average bag or shaker, large salt producing companies mine poor quality rock salt from the earth, then dry it in large kilns.
Does Salt Water Conduct Electricity? A Salt Water …
This is because salt water is a good conductor of electricity which makes ocean water a resource for renewable energy. Salt molecules are made of sodium ions and chlorine ions. (An ion is an atom that has an electrical charge because it has either gained or lost an electron, also meaning it has a positive charge and a negative charge)
Neutralisation Reactions Chemistry Tutorial
Example: Writing a Net Ionic Equation for a Neutralisation Reaction In a net ionic equation, species that are ions in solution and that do not take part in the reaction are not shown. Ions that do not take part in the reaction are referred to as spectator ions. Example: Wtite a balanced net ionic equation for the reaction in which sulfuric acid is neutralised by potassium hydroxide.
Balance the Chemical Equation for the reaction of …
Therefore this is now a balanced equation. Whenever we balance an eqaution you have to change the nuer of molecules used represented by the big nuers before a molecule e.g 2HCl. You cannot change the subscript (small) nuers as this is the nuer of each element in a molecule, and you would end up making up your own molecule that doesn''t make sense!
