Question What is the theoretical yield of HCl if 30.0 g of BCl3 and excess H20 are reacted
according to the following balanced reaction?
BC13(8) + 3 H20(1) - H3BO3(s) + 3 HCl(s)
4
5
The following molar masses are:
HCI = 36.46 g/mol
BCl3 = 117.17 g/mol
H20 = 18.02 g/mol
O 75.9 g HCI
132 g HCI
187 g HCI
56.0 g HCI
28.0 g HCI

there is none because earth is stationary and flat.

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.
