Considering particles at the subatomic level, carrying out this experiment would help to identify the metals given that: Ca has the larger/smaller atomic radius. In chemical reactions, it would be easier/harder
for it to lose its valence electrons to form ions. This means it has comparatively higher/lower ionization energies and would react more quickly/slowly
with the water.

What does the law of increasing costs say? a. as you make more and more of one good or service, you will also make more and more of another. b.as you make less and less of one good or service, you will also make less and less another. c.as you make more and more of one good or service, you will make less and less of another. d.there is no change in production levels when you shift from one good or service to another
