What are the word equation for the reaction that causes sodium to tarnish?
Sodium+Oxeygen->Sodium Oxide 4Na+O2->2Na2O
What causes gold to tarnish?
gold doesn't tarnish.
What causes tarnish?
Tarnish is oxidation caused by exposure to air.
What causes potassium to catch fire?
Let's look at the equation for the reaction of potassium and water: Potassium + water --> potassium hydroxide + hydrogen The reaction is fast and generates sufficient heat (it is exothermic) for the hydrogen gas produced to react with oxygen in the air. The presence of potassium gives the flame a lilac colour as the hydrogen burns. In comparison, lithium and sodium are less reactive so the reactions are slower and produce less heat so the hydrogen gas produced does not ignite. So, the potassium does not burn, the hydrogen does!
Hydrochloric Acid and Magnesium reaction?
First, the balanced equation of the reaction must be considered: Mg + HCl = MgCl2 + H2 Mg + 2HCl = MgCl2 + H2. Notable results in the reaction are the liberation of the H2 which causes bubbles, and the formation of the MgCl2 which causes a foul odor.
What are the chemical and word equations for the reaction that causes potassium to tarnish?

What are the word equation for the reaction that causes sodium to tarnish?
Sodium+Oxeygen->Sodium Oxide 4Na+O2->2Na2O
How does lithuim react with oxygen?
Lithium reacts with oxygen by causing it to tarnish. This reaction is magnified if heat is applied which causes tarnish to form very quickly when compared to exposing to oxygen alone.
What causes gold to tarnish?
gold doesn't tarnish.
What causes tarnish?
Tarnish is oxidation caused by exposure to air.
Why does new shiny copper becomes coated with dark layer after na few months?
it oxidizes..exposure to the oxygen in the air causes it to tarnish...

What causes ignition when water reacts with potassium?
The reaction of potassium with water is highly exothermic. That is, it gives off a lot of heat. Hydrogen, which is formed by the chemical reaction is ignited by this heat and so explodes.
Why causes gold jewelry to tarnish on skin corrosion?
Well, the gold it is tarnish natural; but is it's more tarnish if it's mix with silver or brance or lead or cooper.
How does pewter age?
The air causes it to tarnish, it is called patina

Why do some lotions and cosmetics tarnish silver on contact?
Because it contains Sulfur and sulfur reacts with the silver forming hydrogen sulfide, which causes the tarnish
