Magnesium reacts with water to produce magnesium hydroxide and hydrogen gas.
Mg + 2H2O ---> Mg(OH)2 + H2
The metal that reacts slowly with cold water to form a hydroxide is magnesium. When magnesium reacts with water, it forms magnesium hydroxide and hydrogen gas.
The white powder formed when magnesium reacts with steam is magnesium oxide.
When magnesium reacts with phosphorus, they form magnesium phosphide. This compound is typically a gray solid and can release highly toxic phosphine gas when it reacts with water. The reaction is exothermic and can occur at high temperatures.
When magnesium reacts with oxygen, it forms magnesium oxide (MgO).
Magnesium reacts with oxygen to create magnesium oxide. Magnesium(Mg)+Oxygen(O2)--------> magnesium oxide(MgO) 2Mg+O2 ------>2 MgO
Magnesium Chloride and water would be formed. MgO + 2HCl ------> MgCl2 +H2O
One example of a substance that reacts with water to form a gas is sodium metal. When sodium reacts with water, it produces hydrogen gas and sodium hydroxide. This is a highly exothermic reaction that can be dangerous if not conducted properly.
Potassium reacts vigorously with water, producing hydrogen gas and forming potassium hydroxide. Magnesium reacts slowly with water, liberating hydrogen gas and forming magnesium hydroxide. Copper does not react with water at room temperature due to its low reactivity with water molecules.
magnesium and water? Well mg reacts better with steam which is still h20. mg + 2H2O = 2mgO
Magnesium Hydroxide forms. MgO + H2O = Mg(OH)2
Magnesium. I believe Magnesium does not react to fresh water but salt water is very corrosive and will disolve the metal.
When magnesium reacts with nitrogen, it forms magnesium nitride (Mg3N2).
