Hello
*Homework Question* {34:51} *answer*


(i) Change in colour: Reaction between lead nitrate solution and potassium iodide solution. Pb(NO3)2(aq)+2KI → PbI2(s)+2KNO3(aq)

(ii)Change in temperature: Action of dilute sulphuric acid on zinc.
Zn(s) + H2SO4(aq) → ZnSO4(aq) + H2

(iii) Formation of precipitate: Action of barium chloride on sodium sulphate.
BaCl2(aq) +Na2SO4(aq) → BaSO4(s) +2NaCl(aq)

BY THE WAY, SESSION IS VERY NICE :}

Change in colour: 2Pb3O4 (s) (red colour) 6PbO(s) (yellow colour) + O2(g). Change in temperature: C(s) + O2(g) CO2(g) + Heat + Light. Formation of Precipitate: Pb(NO3)2 (aq) + 2KI(aq) PbI2(s) + 2KNO3(aq).

Answer to homework question
(i) Change in colour: Reaction between lead nitrate solution and potassium iodide solution. In this reaction, colour changes from colourless to yellow.

(ii)Change in temperature: Action of dilute sulphuric acid on zinc. Zn(s) + H2SO4(aq) → ZnSO4(aq) + H2 In this reaction, heat is evolved (iii) Formation of precipitate: Action of barium chloride on sodium sulphate. BaCl2(aq) +Na2SO4(aq) →  BaSO4(s) +2NaCl(aq) BaSO4(s) - ppt

Thank u for this session ma'am 🥰🥰.

Next session???

[Rakeshkumar-ficn]

Q.1
B is Correct because Ag is less reactive then Cu😊

[angelathomas]

Ma'am its written class 9 on the first page

[shalinigupta]

Q1) B
Q2) A
Q3) According to the law of conservation of mass we always need to balance an equation so as to conserve the masses

[sunitayadav]

b because silver is less reactive than copper
