Question

The correct thermochemical equation is-

  1. C+O2→CO2,ΔH=–94Kcal    
  2. C+O2→CO2,ΔH=+94.0Kcal    
  3. C(s)+O2(g)→CO2(g),ΔH=–94Kcal    
  4. C(s)+O2(g)→CO2(g),ΔH=+94Kcal    

The correct answer is: C(s)+O2(g)→CO2(g),ΔH=–94Kcal

a simple meter-bridge circuit, the both gaps are bridge by coils P and Q having the smaller resistance. A balance is obtained when the jockey key makes contact at a point of the bridge wire 40 cm from the P end. On shunting the coil Q with a resistance of 50Ω the balance point is moved through 10 cm . What are the resistance of P and Q
