Question

Q3.a) How will you show that the given equation follows law of conservation of mass? Zn+H 2 SO 4 longrightarrow Zn; S*O_{4} + H_{2}; 1Zn = 65 , H = 1 , S = 32 , O=16]​

Answer 1

Answer:

H2 (g) + Cl2 (g) → 2HCl (g)

(b) 3BaCl2 (s) + Al2(SO4)3 (s) → 3BaSO4(s) + 2AlCl3 (s)

(c) (c) 2Na(s) + 2H2O (l) → 2NaOH (aq) + H2 (g)

Explanation:

I hope it will help you

Answer 2

Answer:

H2 (g) + C12 (g) + 2HCI (g) (b) 3BAC12 (s) + Al2(SO4)3 (s) → 3BASO4(s) + 2AIC13 (s) (c) (c) 2Na(s) + 2H2O (1) → 2NAOH (aq) + H2 (g)
