Mercury is often used as an expansion medium in a thermometer. the mercury sits in a bulb on the bottom of the thermometer and rises up a thin capillary as the temperature rises. suppose a mercury thermometer contains 3.550 g of mercury and has a capillary that is 0.190 mm in diameter.
how far does the mercury rise in the capillary when the temperature changes from 0.0 degrees celsius to 25.0 degrees celsius? the density of mercury at these temperatures is 13.596 g/cm^3 and 13.534 g/cm^3, respectively.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

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.

what is the question here. i think you messed up.
