Balance the following reactions:

Mg(CH:02)2 +K2CO3 →KCH:02 +MgCO
b.
Na +Cu(PO)–Na PO+Cu
c.
Rb +O2→Rb20

Mg-26 and mg-24 are pair of isotopes. isotopes are defined as atoms of the same element having same atomic number but different mass number. i hope that was .

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.

I'm sorry i cant you if you don't list the elements : (
