Write a hypothesis that answers the lesson
question, "While observing a chemical reaction,
how can you tell which reactant is limiting?"
Hypothesis: If a substance is the limiting
reactant, then..
because

i can ! i just need to know what the paragraph is! : p

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)

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.
