Hw answer
1) Heat - CaCo3 CaO +CO2
2) light - 2AgCl ---- 2Ag + Cl2
3) electricity - 2H2O --- 2H2 +O2
Loved the session..

[sujalkumar]

Thankyou VEDANTU for doing so much effort for us.

[raman]

The need to make water acidified is . So that ions can dissociate easily and can be collected on cathode and anode.

[salonisingh]

Home work, 2H2O } 2H2 + O2 heat, electricity
2AgCl __ 2Ag + cl2. Sunlight
CaCo3___ CaO +CO2 heat
Dear Anubha mam session was amazing, I'm little depressed because I do small mistakes in some questions 😔😔😔 but I will cover it in 3 months
And I got 7 marks out of 12 , I do hard marking !😜😜😜😜😜😜🤭🤭🤭🤭🤭🤭🤭🤭
😉🔥🔥🔥🔥🔥🔥🔥🔥🔥And mam please take a session for activities in ncert 👩👩👩👩 its my humble request to you

[adityajain]

Hw Answer-
Decomposition reaction requiring heat is known as thermal decomposition,
+ CO2.


Decomposition reaction requiring light is known as photo chemical decomposition reaction,
+ Cl2.


Decomposition reaction which requires electricity is known as electro chemical decomposition reaction,
Na+ + Cl-.
Njoyed a lot
Can't wait for next session after 2 days
We are glad to get tips and tricks from our AG Mam

[radhasridharan]

Heat : CaCO3➡️ CaO+CO2
Light: 2AgCl ➡️ 2Ag+Cl2
Electricity: 2H2O➡️ 2H2+O2

[syedmobashshirjamil]

WHEN ACID IS ADDED TO WATER IT BREAKS AND GIVE H+ IONS WHICH WILL HELP IN CONDUCTING ELECTRICITY, AND THUS WE ACIDIFY WATER TO MAKE IT CONDUCT ELECTRICITY.

[RAHULJAIN-llfr]

Heat: Caco3 - Cao + Co2
Light: Agcl2 - Ag + Cl2
Electricity: H20 - H2 + O2

[Shreya-enou]

Hw ans: light H2O gives H2 + O2
Light: 2AgCl on heating gives 2Ag +Cl2
Heat: CaCo3 gives CaO +Co2
Mam crystal clear!!🙌

[surendharsurendhar]

acidifying water: to increase the concentration of hydrogen ions [H+]

[reetikagupta]

Session was amazing as always

Homework

CaCO3- CaO
(Thermal)
2H2O- 2H2 + O2
(Electrolysis)
AgBr - Ag+ Br
(Light)

[KhushbuKumari-ttpm]

Homework Heat -2 fe so 4 ---> fe2 O3 + SO2 +SO3, light - 2 Ag Br 2Ag + Br , electricity - 2 NaCl ----> 2Na + Cl 2, its amazing session, thanks Ma'am 😊

[Santoshsingh-zgym]

Hw answer
1)thermal decomposition of Feso4.
2)decomposition of Agcl2 in presence of sunlight.
3)eletrolysis of water...


Thankyou

[Heisenberg-]

Thermal decomposition
2FeSO4(s)--->Fe2O3 (s) + SO2 (g) + SO3 (g)

Electrolytic decomposition
2H2O(l)----> H2 (g) + O2 ( g)

Photolytic decomposition
2AgCl 2Ag (s) + Cl2 (g)


Thankq mam...loved it ....

[dharmendrabhardwaj]

Hw
Agbr2 in presence of light convert into ag and br2
Breaking of water in h2 and 02 when electricity is passed through it
Breaking down of lead nitrate into
Lead oxide nitrogen di oxide and tri oxide

[archanapandit]

Homework
Thermal
Photo lytic=Agbr>Ag+br2
Electrolytic=Nacl>na+cl2
The session was incredible and imazing. Thanks you mam for such a wonderful session

[sujalkumar]

Your teaching is amazing mam.
Loved the way you teaches.

[dnyaneshb]

HW answer is 1) CaCO3 CaO + CO2 ( Thermal decomposition )
2) 2Al2O3 4Al + 3O2 ( Electrolytic decomposition )
3) 2H2O2 2H2O + O2 ( Photolytic decomposition )

GREAT SESSION MAM....FAN OF YOURSF !!

[gayathrisujith]

maam homework
1) heat decomposition reaction
CaCO3--->(HEAT)-->Cao+CO2
2)light decomposition reaction
PbNO3-->(LIGHT)-->PbO+NO2+O2
3)electric decomposition
H2O-->(electicity)--> 2H2+O2

[sreevalisappa]

Homework answer..
Decomposition by heating
FeSO4 - - > Fe2O3 + SO2 +S03
Decomposition by light
2AgCl--> 2Ag + Cl2
Decomposition by electrolysis
2H2O--> 2H2 + O2

Thank you mam for the sprint class!!
