Ca Calcium. Just did a chem test now, got it right.
Because it will spontaneously react with the oxygen in the air.
Water does react with aluminum carbide. The metal actually decomposes in water and produces methane.
A basic solution
Yes, oxygen is in water. Water and metal create rust.
They are both extremely reactive. They react spontaneously with air, water, and even the weakest of acids.
Sulfur doesn't react with water.
Because it will spontaneously react with the oxygen in the air.
For example uranium react with oxygen but not with water.
Magnesium. I believe Magnesium does not react to fresh water but salt water is very corrosive and will disolve the metal.
No, the metal will react strongly with water.
A metal that does not react to acid, oxygen or water does not exist.
Europium is the most active of the lanthanides. it reacts quickly with water to give off hydrogen. it also reacts strongly with oxygen in the air, catching fire spontaneously. Scientists must use great care in handling the metal.
Water does react with aluminum carbide. The metal actually decomposes in water and produces methane.
A basic solution
Protactinium is a reactive metal; protactinium react with water vapours, acids, oxygen, halogens,etc.
Yes, oxygen is in water. Water and metal create rust.
They are both extremely reactive. They react spontaneously with air, water, and even the weakest of acids.
