The formula sprays on with ease and loosens up calcium deposits without scrubbing. You can use it on sinks, fixtures, tubs, tiles, showers, and glass, and it''ll even remove soap scum and rust
While the Ca metal anode is by far the most promising cell design, the electrochemistry of Ca metal is rather complex, including the role of the very stable calcium oxide. An Ellingham diagram (69) plots the standard free energy of formation of oxides with temperature, and it usually also provides the partial pressure of oxygen at equilibrium (Ellingham–Richarson diagram, as shown in Figure 4 ).
From its chemical formula, Ca(NO3)2, you can tell that there are two nitrate ions for every calcium atom. Therefore the mole ratio of calcium to nitrate is 1:2. So one could say that

i) The atomic nuer of calcium is 20. Its electronic configuration is 2,8,8,2. The valency of calcium is +2. Hence it is a metal belong to the group 2. ii) The radius of calcium is smaller than potassium because both elements lie in the third period of the periodic table. Potassium lies to the left of calcium in the period, and atomic size decreases, going left to right due to increase in the
