2Sn+O2=?

The reaction between tin (Sn) and oxygen (O₂) produces tin(II) oxide if it is a simple oxidation reaction. The balanced equation for this reaction is: \[ 2 \text{Sn} + \text{O}_2 \rightarrow 2 \text{SnO} \] This means that two moles of tin react with one mole of oxygen to produce two moles of tin(II) oxide. If you need to consider different oxidation states of tin, tin(IV) oxide (SnO₂) can also be formed under certain conditions, which has the balanced equation: \[ 4 \text{Sn} + \text{O}_2 \rightarrow 2 \text{SnO}_2 \] Make sure to clarify which product you need based on the reaction conditions.
