Ca2 plus ions separate from Mg2 plus ions?
they cannot bond together, they are separate .
Is ca plus 2 or mg plus 2 larger?
The Ca2+ ion is larger than the Mg2+ ion. The ionic radii are: 86pm for the Mg2+ and 114pm for the Ca2+. Besides the fact that the Ca2+ has more electrons this can be explained by the principle of electron shielding. Electron shielding is when lower level electrons block the EFC(effective nuclear charge) from effecting the valence electrons of an ion. Ca2+has more electrons than Mg2+ so more electron shielding occurs.
What is the average hardness of a bottle of water?
Total hardness=(Ca2+)*(combining weight of CaCO3/combining weight of Ca2+) +(Mg2+)(combining weight of CaCO3/combining weight of Mg2+)
What is the chemical symbol of hard water?
CaCO3 calcium carbonate
What is the electronic configuration of mg2 plus?
Mg2+: [1s22s22p6]

What is the element that binds to troponin?
Ca2+ , Mg2+ .
Which ion has the smallest ionic radius Mg2 plus or Ca2 plus?
Mg is in period 3. Ca is in period 4. Down a group the size increases. So Mg is smaller than Ca.

How does borax serves as water softening agent?
When Borax is added to water, it reacts with Ca2+ and Mg2+, which come out of water as precipitates. The reactions involved are: Ca2+ + Na2B4O7 ----> CaB4O7 + 2Na+ Mg2+ + Na2B4O7 -----> MgB4O7 + 2Na+

What is the chemical symbol of hard water?
CaCO3 calcium carbonate
What is the electronic configuration of mg2 plus?
Mg2+: [1s22s22p6]
What are the major elements found in water?
