Question

Balance the following equation : (I) Na2O2 + H2O ----- NaOH + O2 (ii) CI2 + NaOH ------ NaCI + NaCIO3 + H2O (iii) Cu + HNO3 ----- Cu(NO3)2 in 2 marks​

Answer 1

2Na2O2 + 2H2O → 4NaOH + O2

6NaOH + 3Cl2 → 5NaCl + NaClO3 + 3H2O

3Cu+8HNO3​⟶3Cu(NO3​)2​+2NO+4H2​O

please mark me brain mark list

Answer 2

Answer:

2Na202 + 2H2O → 4NaOH + O2

6NaOH + 3C12 → 5NaCl + NaCIO3 + 3H2O

3Cu+8HNO3-3Cu(NO3)2+2NO+4H20
