Heat makes a metal expand. If you take a metal ball and an metal loop that the ball fits in and then heat the ball and try to put it back in the loop it will not go back through. :)
The metal of copper can react with oxygen. This is a metal that is very reactive when ti is combined with different substances.
When alkali metals react with ammonia, they form metal amides and hydrogen gas. The reaction is highly exothermic, releasing a significant amount of heat. The metal amides are ionic compounds, and the overall reaction is generally more vigorous than the corresponding reactions with water.
Gold is a metal that does not react with oxygen when heated, even at high temperatures. This is because gold is a noble metal with low reactivity.
You want something that reacts with water and is exothermic. An example would be an alkali metal (such as sodium), or perhaps oxygen salts that react with water
Neptunium is a reactive metal and can react with the majority of non metals.
It elongates
Sulfur doesn't react with water.
Gold is a metal that does not react with bases. It is a noble metal, meaning it is resistant to corrosion and does not easily react with other substances.
Metals are generally good conductors of electricity and heat. They react with acids to produce salts. They are malleable and ductile.
Gold is a metal that does not react with most acids or water.
Two substances that can react with hydrochloric acid to form salt are metal oxides and metal carbonates. When metal oxides react with hydrochloric acid, they form metal chloride and water. When metal carbonates react with hydrochloric acid, they form metal chloride, carbon dioxide, and water.
When alkali earth metals react with water, they produce metal hydroxides and hydrogen gas. The reaction is generally violent and releases heat.
Potassium is one of the most reactive metals and will react violently with an acid, producing hydrogen gas and a lot of heat. This reaction can be dangerous and should be done with caution.
Calcium does not react with metal because it is a metal.
Sodium is a metal that will react spontaneously with water, producing sodium hydroxide and hydrogen gas. This reaction is highly exothermic and can be violent, often resulting in the production of heat and flames.
no
A metal and a non metal. Two non metals. A metal and a metalloid.
