when red leadoxide is heated it gives lead and oxygen i think.
When heated, red lead oxide (Pb₃O₄) decomposes into lead monoxide (PbO) and oxygen gas above 550°C. The decomposition reaction can be represented as 2 P b 3 O 4 ( s ) → 6 P b O ( s ) + O 2 ( g ) . This process is important in various chemical applications, but caution is necessary due to the toxicity of lead compounds.
