1 When a warm solution of sodium sulphate is electrolysed using platinum electrodes, oxygen gas is liberated at the anode. However, when a warm solution of sodium sulphate is electrolysed using
graphite electrodes, a mixture of oxygen, carbon dioxide and carbon monoxide are liberated at the
anode. Explain the observations,​

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.

I'm sorry but i'm only grade
