Answer 1

21. Ans - Ma (ot) and Belot₂ 30, I moles of mq (ht) will will not react react. with o mole of Berlin 22. Ans; The clinical reaction is maint) + HNO3 mg (NO3)2 + 40. The balanced equation is mg (0+)₂ + 2HNO₃ - Mg(NO3)2 + 240. 30, Inde of my (onth, reacts with a moles of HNO₃ 23. Ans; - The chemical reaction is Mg(OH)2 + (20g - Mg CaO + Ho The balanced equation is - mg (OH)2 + $1200 mg (20g + 240 One mole of Malat) reacts with Imde of $26209. 24. Ans - The reaction is malonta + $500 - masoa + 20 The balanced equation is Mg(OH)2 + 14500 → masoa + 2140 Imole of mg (ot), reacts with I mole of 450g. 25. Ans - The reaction is mg (OAL + H₂PO4 - Mg3(PO4)₂ + 40

- The balanced equation is 30g (0A2 + 2HPO4 - mp3lPO4)2 + 6160 3 moles react with a moles of 43 P09 Imole will react with 2 x I mbes. of H3PO a 50.67 moles of my pod
