The first chemical reaction is the conversion of phosphorous acid (H3PO3) to phosphoric acid (H3PO4) and phosphine gas (PH3).
2H3PO3 -> 2H3PO4 + PH3
The second chemical reaction is the decomposition of copper(II) nitrate (Cu(NO3)2) to copper(II) oxide (CuO), nitrogen monoxide gas (NO), and oxygen gas (O2).

The second chemical reaction is the decomposition of copper(II) nitrate (Cu(NO3)2) to copper(II) oxide (CuO), nitrogen monoxide gas (NO), and oxygen gas (O2).
2Cu(NO3)2 -> 2CuO + 4NO + O2
