When the valency of calcium is 2 plus and the valency of carbide is 4- how does calcium carbide get the formula CaC2?
CaO + 3C >> CaC2 + COThis reaction can not be produced at a normal temperature achieved by combustion, but in an electric arc furnace. I can find out no more than that.Added:because the 'valency' of carbide is NOT uniqely -4: Actually in metal salts it's ion is (C2)2- , so with Ca2+ it forms CaC2The structural formule is not C-Ca-C but -Ca-(C=C)- formed in a chain with a triple bond between the Carbon atoms: ..... -Ca-C---C-Ca-C---C-Ca-..... etc.Even in ethyn H2C2 it is considered to have a -2 valency, though this is not a ionic (metal) salt.

What is the CA mintmark on the Gaudens double eagle stand for?
I also have a double eagle with the ca mint mark. The ca is a 1908 with the C over stamped on the A. What does it stand for? The 'CA' is not a mint mark on the $20 Saint Gaudens gold double eagle. The mint mark on that coin is found ABOVE the date, not below. The 'CA' is not CA, it is actually 'ASG', the designer's initials: Augustus Saint Gaudens. The confusion is understandable, for 2 different reasons: A) The mint mark on US coins of that period is commonly under the date; and B) 'ASG' is hard to decipher, as the letters are on top of each other. At first glance it looks like a 'C', with an 'A' hung on the bottom of the 'C'. For a more details regarding this coin, see http://www.coinace.com/saint-gaudens-history.aspx
