When deployed, car air bags rapidly inflate as sodium azide, NaN₃, decomposes into it's component elements, given by the following reaction: 2 NaN₃-> 2 Na + 3 N₂ a) How many grams of NaN₃ are required to form 5 grams of nitrogen
gas? b) How many grams of sodium are produced from that amount of sodium azide? (use your answer from 4a)

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.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.

use quiz let it tells you all the answers thats what i use
