8:05 option d basic acidic basic
20:39 ii The litmus paper shows change in colour when it is wet.
iii Dry HCL gas will show no acidic characters because it cannot form or dissociate Hydronium ions due to absence of Water. HCl solution will show acidic characters because it dissociates Hydronium ions in presence of water
34:51 Zn + HCL ----) ZnCl² + H²
To test the presence of this gas we use pop sound test. Hydrogen burns with a Pop sound and extinguishes the candle.
1:06:52 option d
1:10:34 option c
1:21:14 i G- Cl² C - CaOCl²
ii NaCl + H²0 + electricity ----) NaOH + Cl² ( anode) + H² ( cathode)
Cl² + Ca(OH)² ----) CaOCL² + H²O

Electric Current and Circuit :-
1. Ohm's Law:
- V = IR (Voltage = Current x Resistance)
- I = V/R (Current = Voltage / Resistance)
- R = V/I (Resistance = Voltage / Current)
2. Power:
- P = VI (Power = Voltage x Current)
- P = I^2R (Power = Current^2 x Resistance)
- P = V^2/R (Power = Voltage^2 / Resistance)
3. Energy:
- E = Pt (Energy = Power x Time)
- E = VIt (Energy = Voltage x Current x Time)
Resistance and Resistivity
1. Resistivity:
p = RA/I (Resistivity = Resistance x Area /
Length)
2. Resistance:
- R = pl/A (Resistance = Resistivity x Length /
Area)
3. Combination of Resistances:
Series: R_total = R1 + R2 + + Rn
Parallel: 1/R_total = 1/R1 + 1/R2 + + 1/Rn
Electric Potential
1. Electric Potential:
- V = W/q (Voltage = Work / Charge)
Other Formulas
1. Kilowatt-hour (kWh):
1 kWh = 1000 Wh = 3.6 x 10^6 J
2. Fuse and Circuit Breaker:
- I = V/R (Current = Voltage / Resistance)
Units and Conversions
1. Volt (V)
2. Ampere (A)
3. Ohm (Ω)
4. Watt (W)
5. Joule (J)
6. Kilowatt-hour (kWh)

Thank you sir 💖🥺
To all the 10th grader........trust me god has gave you guys a gem for your 10th boards.....inse padh ke agar tumhe science me full marks nhi aaye to kisise padh ke nhi aa skte 😂..........
Shi kh rha hai bhai 😅 bhagwaan ne new year ka gift diya hai 10th walo ko
Sir I teach chemistry to the students offline when I heard you are back to teach I came here to see my old Alakh sir ...lots of respect to you sir ❣️🙏🏻...I saw you at the lowest and when I see you at this stage where each and every student know PW I feel so so happy sir...need your blessings sir 🙌🏻❣️
35:09 the correct answer will OPTION 'C'
Nope. Because in option C, its written NaZnO2 while it should be Na2ZnO2. So option B is correct 😊
Once a legend always a legend ❤️❤️ love you Alakh sir ❤❤
18:54 Dry litmus :- chii🤮
Moist litmus :-wow🤯😯
8:08 Option - (D)
Sir plz kal parso takk metals and non metals daal do 1:30 ghnte mein.... Wednesday ko preboards hai aur metals and non metals bilkul clear nahi hua hai
PREBOARD 2ND OR 1 ST ?
1st
2nd is from 20th
Is baar to class me jalwa hoga kyuki mere siwa koi pw se nahi padta meri class me
Ab to phodkar aunga 🔥🔥🔥
