12.00g of compound x with molecular formula c3h6 are burned in a constant-pressure calorimeter containing 40.00kg of water at 25°c. the temperature of the water is observed to rise by 3.338°c. (you may assume all the heat released by the reaction is absorbed by the water, and none by the calorimeter itself.) calculate the standard heat of formation of compound x at 25°c.

H tricky one let me think and get back to u

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m

  you would need a flashlight, escape plans, canned foods, blankets, phone, car, money, clothes, and some more things that you think would be to get you out of the disaster safe and soundhope.  this : )
