@@oandalevelscience8301 when will you upload the rest of the questions of this paper? Like in Q 21 how did you know it was naclo3 and not naclo? I mean it wasnt mentioned if naoh was hot or cold so did you found that out?

@@winxclubflora8446 will be uploading the next part soon as for q21 we have to find the number of oxygen by balancing the equation
NaOH + 3Cl2 ------> 5NaCl
3 moles of Chlorine already given and 5 mole NaCl formed also given and another compound formed must have 1 Na and 1 Cl as the options suggest....in order to balance the H's we need to add 3 moles of H20 that leaves us with 3 oxygen molecules to balance the equation giving an overall equation of
6NaOH + 3Cl2 ----> 5NaCl + NaClO3 + 3H2O
