No, water is a metal. It's chemical symbol is H20.
To prove this, get a crowbar and a clear glass of water. They look the same because thay are the same material.
Ice is a non-metal. It is frozen water.
NO2 is a non-metal oxide. Nitrogen dioxide (NO2) is composed of nitrogen and oxygen, both of which are non-metals on the periodic table. Non-metal oxides typically form acidic solutions when dissolved in water, as they react with water to produce acids. In contrast, metal oxides tend to form basic solutions when dissolved in water.
When a non-metal oxide, such as sulfur dioxide, is dissolved in water, it forms an acidic solution. This is because non-metal oxides react with water to produce acids.
well, not metal+metal, but for the other 2 you'd have to specify, because water+metal=good conductivity & just water or another liquid = good conductivity. now stone, it is a horrible conductor.
Sulfur doesn't react with water.
Non-metal
Non-metal oxides are compounds that contain a non-metal element bonded with oxygen. They tend to be acidic in nature and can react with water to form acids. Non-metal oxides play a role in atmospheric chemistry and can contribute to acid rain when they dissolve in water droplets.
Water
In chemistry, the terms metal and nonmetal are reserved for elements. Water is a compound of two different elements: hydrogen and oxygen.
The Metal hydroxides are strong base, therefore metal hydroxide decomposes on heating to form metal oxide and water.
When a non-metal oxide reacts with water, it forms an acid. For example, sulfur dioxide reacts with water to form sulfuric acid. The reaction between the non-metal oxide and water releases heat as the acid is formed.
Carbon is a non-metal that is commonly used in water purification processes. It is used in the form of activated carbon to adsorb impurities, such as chemicals, organic compounds, and pollutants, from water.
