Just need help with this question, I'm having a hard time. An answer and an explanation would be great. An unknown hydrocarbon contains carbon, hydrogen, and oxygen. Combustion of 1.5000 g of
the hydrocarbon produces 1.1738 g H 2 O and 2.1505 g CO 2 . What is the empirical formula of the
hydrocarbon?

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.

b. is the answer hoped i        

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
