What 3 properties did Mendeleev write on his cards to organize 63 elements?

He wrote each element's melting point, density, atomic mass, and color on cards. The atomic mass of an element is the average mass of all the isotopes of that element. He tried arranging them in different ways.

This is what i found on google “when one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and atp is converted to adenosine diphosphate (adp). likewise, energy is also released when a phosphate is removed from adp to form adenosine monophosphate (amp).” i hope this you .
