phosphorus burns in the limited supply of air to form phosphorus(iii)oxide, P4O6 and in unlimited supply of air to form phosphorus(v)oxide P4O10. If 3.3g of phosphorus(iii)oxide is formed what mass of oxygen from air is used

what is the volume occupied by 40 grams of argon gas (ar) at standard conditions? what volume, in liters, is occupied by 1.5 x 1023 

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

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.
