predict the type of radioactive emission produced from the decay of metastable cobalt 60 to cobalt-60. describe this type of
emission and its reaction to an electric field.
during the radioactive decay, alpha particles are released. these positive
particles are attracted to the negative plate in the electric field and
represent a ground energy level
beta particles are released during the radioactive decay. these negative
particles are attracted to the positive plate in the electric field and
represent an excited energy state.
radioactive gamma decay is produced by the reaction. this neutral
electromagnetic radiation allows the isotope to return to its ground state
and is not attracted to the electric field
both types of radioactive emissions, particles and electromagnetic
radiation are produced during this decay. none of these are attracted to
the electric field and both present an intermediate level

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.

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.
