I need help with these 2 questions if possible:

- An excess of Mg(s) is added to l00. mL of 0.400 M HCl. At 0°C and 1 atm pressure, what volume of H2 gas can be obtained?

- 2 H2O(l) + 4 MnO4-(aq) + 3 ClO2-(aq) →4 MnO2(s) + 3 ClO4-(aq) + 4 OH-(aq)

According to the balanced equation above, how many moles of ClO2-(aq) are needed to react completely with 20. mL of 0.20 M KMnO4 solution?


Thanks in advance!
