Question

(m) Aluminium sulphate + sodium hydroxide → sodium sulphate + sodium meta aluminate + water
(n) Aluminium + sodium hydroxide + water =sodium meta aluminate + hydrogen
(o) Potassium dichromate + sulphuric acid → potassium sulphate + chromium sulphate + water + oxygen
(p) Potassium dichromate + hydrochloric acid → potassium chloride + chromium chloride + water + chlorine
(9) Sulphur + nitric acid → sulphuric acid + nitrogen dioxide + water
(r) Sodium chloride + manganese dioxide + sulphuric acid → sodium hydrogen sulphate
+ manganese sulphate + water + chlorine
write the balanced chemical equations for these questions plz write balance one not only equations...no spamming plz beat ans will be marked as brainliest​

Answer 1

(m)Al2(SO4)3 + 8NaOH 2NaAlO2 + 3Na2SO4 + 4H2O

Al2(SO4)3 + 8NaOH 2NaAlO2 + 3Na2SO4 + 4H2OGENERALLY for balancing u should first balance the central atom of all compounds and then remaining metals and at last go for oxygen and hydrogen.

Al2(SO4)3 + 8NaOH 2NaAlO2 + 3Na2SO4 + 4H2OGENERALLY for balancing u should first balance the central atom of all compounds and then remaining metals and at last go for oxygen and hydrogen.The above reaction is easy enough which can be balanced by hit and trial method but many complicated ionic reactions can be balanced by some methods life ion-electron and many other.
