A basic solution
A metal Hydroxide.
The Metal hydroxides are strong base, therefore metal hydroxide decomposes on heating to form metal oxide and water.
When a metal oxide reacts with an acid a slat and water are formed.
Magnesium oxide react with water and magnesium hydroxide is formed.
A reaction between an acid and a metal oxide to form a salt and water as the only products.

Magnesium oxide react with water and magnesium hydroxide is formed.
A reaction between an acid and a metal oxide to form a salt and water as the only products.
A slow metal reaction with air and water will form a metal oxide. An example of this is iron oxide, better known as rust.
A salt and water.
Insoluble metal oxide + strong acid ---> salt + water
Metal oxides form alkalis when they dissolve in water. Non-metal oxides for acids. For example: carbon dioxide + water --> carbonic acid magnesium oxide + water --> magnesium hydroxide
Acid
A salt of copper and water would be formed as products.
Rust it is an oxide, formed by the reaction with oxygen or oxygenated water ; ethane don't react with water.
alkali metal + oxygen --> metal oxide metal oxide + water--> metal hydroxide metal hydroxides are strong alkalis, corrosive pH=14
