please answer quickly thank u 12.00 g of Compound X with molecular formula \( \text{C}_5\text{H}_{10} \) are burned in a constant-pressure calorimeter containing 30.00 kg of water at 25 °C. The temperature of the water is observed to rise by 4.226 °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.Be sure your answer has a unit symbol, if necessary, and round it to 3 significant digits.---A diagram follows, consisting of a rectangular text input box, possibly for entering calculations or answers. Below the box, there is a toolbar with various symbols:- An eraser icon for clearing input.- Squares of different sizes, potentially for formatting or structuring responses.- A multiplication symbol with “x10,” suggesting scientific notation.- A reload or refresh icon, likely for resetting.- A question mark icon, possibly for help or additional information.

Need full case study with results discussion Introduction etc. Dont use guideline answer ok need full accurate case study. Case History A 32 year old male was found unconscious in his flat following a night out with friends. Attempts to resuscitate the male were unsuccessful. The postmortem indicated sudden cardiac death through cardiac dysrhythmia (arrythmia). There was no medical history of previous heart disease. Two opened packets of Jumping Beans were found on a table close to the body. A specimen of cardiac blood was taken and submitted to the toxicology laboratory for analysis along with the two Jumping Beans packets. . Guidance for Preparing the Case Report The coursework assessment for the module is to prepare a case report in the form of a case report scientific paper published in the Journal of Analytical Toxicology. This guidance information has been taken from the Instructions for Authors for the Journal of Analytical Toxicology however please use the…
