Yes if ferrous sulphate contains water then it is hydrated ferrous sulphate of green colour but if ferrous sulphate don't contain water molecules i.e. anhydrous ferrous sulphate of white colour
You're correct😀but in general jb ham khte h ferrous sulphate crystals to vo green colour k hote h..jaise ki CuSO4 bhi white colour ka h jbki CuSO4.5H2O blue colour ka
Mam life process ka lecture kab aayega????❤❤❤❤❤btw you are so beautiful you are my crush mam please 94.6 percent dilwa dijiye please mam❤🥺🥺🥺🥺🥺🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏
Jo log trick trick kar rahe hai, trick yahi hai ki ek paper pe likho aur yaad karo , pahele itna scatter tha mam ne ek page me sab de diya ab aur kya trick chahiye, Itna bhi 🥄 spoon feeding ke addictive na ho jao. Btw Quality content mam🫡

All Formulas of Electricity:
1) I = Q/t
2) Q = ne
3) V = W/Q
4) V = IR
5) R = Rho x L/A
6)Resistance in Series: Rs = R1 + R2 + R3
7)Resistance in Parallel: 1/Rp = 1/R1 + 1/R2 + 1/R3 (» Reciprocal of R1+R2+R3)
8)H = V × Q
i) H = VIt
ii) H = I²Rt
iii) H = V²t/R
9) P = W/t
i) P = VI
ii) P = I²R
iii) P = V²/R
10) E = P × t
S.I. Units:
Current ( I ) - Ampere
Charge ( Q ) - Coulomb
Time ( t ) - Second
Potential Difference or Voltage ( V ) - Volt
Resistance ( R ) - Ohm Ω
Resistivity ( Rho ) - Ohm meter
Power ( P ) - Watt
Heat = Energy = Work = Joule
Measuring Devices:
Ammeter / Milli Ammeter - for measuring current (always connected in series)
Galvanometer - for measuring small/sensitive currents (we can also get the direction of the current)
Voltmeter - for measuring volts (always connected in parallel)
Ohm Meter - Measures the resistivity
Things to remember:
electron charge = (1.6 x 10⁻¹⁹ C)
1kWh= 3.6 × 10⁶J
1Ampere = 1000mA
1 Kilowaat = 1000W
1 Horse Power = 746W
i hope this list will help you! ❤

ferrous sulphate is white and FeSO4.7H2O is green ig?
Yes if ferrous sulphate contains water then it is hydrated ferrous sulphate of green colour but if ferrous sulphate don't contain water molecules i.e. anhydrous ferrous sulphate of white colour
Yes you're correct..here we're mainly talking about the aqueous solution so vo coloured hi hoga..like ham displacement reactions m likhte hai
MAM you are so BEAUTIFUL 😍😍❤️❤️❤️❤️😍😍❤️😍❤️ LOVE U MAM
Ma'am you are beautiful
I really wanted this video
THERE IS A QUESTION
If ZnSo4 is called WHITE VITRIOLE then why its colourless🤔?
thank you mam
Mam adda 247 se hai

Next chapter ma'am pls
Mam FeSO4 white hota hai.
But FeSO4•7H2O green color hota hai
You're correct😀but in general jb ham khte h ferrous sulphate crystals to vo green colour k hote h..jaise ki CuSO4 bhi white colour ka h jbki CuSO4.5H2O blue colour ka
@@studywarehousemam ye aapke channel pe aaple videos kyu nhi aate?😅😅😅
@studywarehouse Yeah but rather than referring to crystals, we should refer the terms Hydrated and Unhydrous crystals.

Jo log trick trick kar rahe hai, trick yahi hai ki ek paper pe likho aur yaad karo , pahele itna scatter tha mam ne ek page me sab de diya ab aur kya trick chahiye, Itna bhi 🥄 spoon feeding ke addictive na ho jao.
