Would you expect the properties of rubidium (Rb) to be more similar to potassium (K) or strontium (Sr)? Explain. *

Strontium

Explanation: They coexist as a method together due to the rubidium-strontium dating method. The rubidium-strontium dating method is a radiometric dating technique used by scientists to determine the age of rocks and minerals from the quantities they contain of specific isotopes of rubidium and strontium.

I’d have to say no because without oxygen in the water the fish would all be dead. so if you want to fish for dead fish, pick the ponds with the lowest oxygen concentrations.

They can measure  the amount of energy gained or lost
