You did not specify the types, but I believe the answer would be gamma radiation.
2Pb²⁺ + O2 -----> 2Pb⁴⁺ + 2O²⁻
(Pb²⁺-2e ----> Pb⁴⁺) *2
O2 +4e ----->2O²⁻
add 2 last equations
2Pb²⁺-4e+ O2 +4e ----> 2Pb⁴⁺+ 2O²⁻
2Pb²⁺ + O2 -----> 2Pb⁴⁺ + 2O²⁻

Answer:
Number of produced moles of carbondioxide is 0.113 mol.
Explanation:
Excess of sulphuric acid is present.And the sodium carbonate is completely consumed.
Molar mass of sodium carbonate = 105.99g/mol
Given mass of sodium carbonate =12 g/mol
one mole of sodium carbonate produce one mole of carbondioxide.
0.113 mole of sodium carbonate produce 0.113 mole of carbondioxide.
Therefore, 0.113 mol of carbondioxide produced in flask 7.
