What are the word and chemical equation for the reaction that cause potassium to tarnish?
The word for the reaction that causes potassium to tarnish is oxidation. The chemical equation for this reaction is 4K + O2 -> 2K2O.
What are the word equation for the reaction that causes sodium to tarnish?
Sodium+Oxeygen->Sodium Oxide 4Na+O2->2Na2O
How can you tarnish a penny?
One way to tarnish a penny is by exposing it to a mixture of salt and vinegar. This combination creates a chemical reaction that causes the copper surface of the penny to darken and tarnish over time.
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!
What causes tarnish?
Tarnish is mainly caused by a chemical reaction between the metal (such as silver, copper, or brass) and sulfur compounds in the air. This reaction forms a layer of corrosion on the metal's surface, which appears as discolored or darkened areas. Factors like humidity, exposure to certain chemicals or substances, and improper storage can also accelerate tarnishing.

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.

when potassium is added to water what causes explosion?
When potassium is added to water, it reacts exothermically with the water to produce potassium hydroxide and hydrogen gas. The rapid production of hydrogen gas in the reaction causes an explosion due to the build-up of pressure from the gas release.
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.
What is the balanced chemical equation for mentos and soda?
The reaction between Mentos (containing nucleation sites) and soda (containing carbon dioxide) is a physical reaction that causes the rapid release of carbon dioxide gas. This reaction is not a chemical reaction, so there is no balanced chemical equation for it.
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
