Typically an acid.
Also for the halogens.
Carbon is a nonmetal. Thus this is a nonmetal oxide.
It forms acidic solutions
analysis
Metal oxide reacting with a nonmetal oxide produces a salt.Examples:CaO + CO2 --> CaCO3PbO + SO3 --> PbSO42 NaO + H2O --> 2 NaOH
Metal oxide reacting with a nonmetal oxide makes a salt.Examples:CaO + CO2 --> CaCO3PbO + SO3 --> PbSO42 NaO + H2O --> 2 NaOH
water is a nonmetal oxide
Carbon is a nonmetal. Thus this is a nonmetal oxide.
No potassium OXIDE is not: IT IS A METAL. IT IS A METAL.And it is not a NONmetal either.Potassium OXIDE K2O is a basic oxide: with water it forms (only) potassium hydroxide, KOHPotassium (elemental) is a alkali metal
It forms acidic solutions
The product of nonmetal oxide water is oxyacid.
analysis
It is a hydration reaction.
Metal oxide reacting with a nonmetal oxide produces a salt.Examples:CaO + CO2 --> CaCO3PbO + SO3 --> PbSO42 NaO + H2O --> 2 NaOH
Metal oxide reacting with a nonmetal oxide makes a salt.Examples:CaO + CO2 --> CaCO3PbO + SO3 --> PbSO42 NaO + H2O --> 2 NaOH
salt
No reaction: nonmetal oxides themselves are acid forming in water hence they react with basic compounds (like hydroxides, carbonates)
The products are a salt and water.
