My physics and chemistry chapters are not completed in 12th Maharashtra board, and exams are approaching. How to do above 50+marks?
Hi.
It's still possible to score 50+ in Physics and Chemistry in your 12th Maharashtra board exams even if your chapters aren't fully completed. The key is strategic preparation and selective focus. Here's a detailed plan:
Step 1: Identify the High-Yield Chapters
Focus on chapters and topics that frequ
I am B.Sc graduate in chemistry, can I pursue MBA from Chandigarh University?
Yes, yes why not, you can pursue MBA from Chandigarh University, it does'nt matter in which course you are graduated. The main eligibility criteria is Bachelor degree in any discipline with atleast 50% marks from recognised University/ Institution. Graduates of recognised professional programmes lik
At 25°C the standard emf of cell having reactions involving two electrons change is found to be 0.295 V. The equilibrium constant of the reaction is :
At 25°C the standard emf of cell having reactions involving two electrons change is found to be 0.295 V. The equilibrium constant of the reaction is :
ΔG° = –RT * 2.303 log K
–nFE° = +RT * 2.303 log K
2 * 96500 * 0.295 = 8.314 * 298 * 2.303 log10 K
10 = log10 K = 1010
Enthalpy of neutralisation of CH3COOH by NaOH is – 50.6 kJ/mol and the heat of neutralisation of a strong acid with NaOH is – 55.9 kJ/mol. The value of ΔH for the ionisation of CH3COOH is :
Enthalpy of neutralisation of CH3COOH by NaOH is – 50.6 kJ/mol and the heat of neutralisation of a strong acid with NaOH is – 55.9 kJ/mol. The value of ΔH for the ionisation of CH3COOH is :
CH3COOH + NaOH → CH3COONa + H2O
ΔH = –50.6 kJ/mol
NaOH + SA [HCl] → NaCl + H2O
ΔH = –55.9 kJ/mol
the value of ΔH for ionisation of CH3COOH
⇒ ΔH = +55.9 – 50.6
5.3 kJ/mol
