Ab nahi bach paoge! #LLAShorts 268

Let's assume that the car, of mass 1550 kg, can reach a speed of 26.8 m/s in 7.1 s. What is the average power needed to accomplish this? (Given : 1 hp = 746 Watt)

The standard EMF of decinormal calomel electrode is 0.268 V . The EMF is

A: One mole of sucrose-reacts completely with oxygen produces 268.8 litre of carbon dioxide at STP. R: Amount of oxygen required for reaction is 268.8 litre.

A gas has a density of 2.68 gL^(-1) at 1 atm and 273 K. Identify it:

?H for the reaction, F_(2)+2HClrarr2HF+Cl_(2) is -352.8 kJ and standard heat of formation of HF is -268.3 kJ mol^(-1) . Calculate standard heat of formation of HCl.
