3ac + 2ca = 3ac + 2ac = (3 + 2)(ac) = 5ac
2Ca(s) + O2(g) ----> 2CaO(s)
The symbol equation for the formation of calcium oxide is: Ca + O2 -> CaO.
Yes, silver and calcium nitrate will react to form silver nitrate and calcium. The balanced equation for this reaction is: 3Ag + 2Ca(NO3)2 -> 3AgNO3 + 2Ca

The balanced equation for the reaction between calcium and oxygen to produce calcium oxide is: 2Ca + O2 -> 2CaO
The oxidation of calcium can be represented by the equation: 2Ca(s) + O2(g) -> 2CaO(s). This reaction involves the combination of calcium metal with oxygen gas to form calcium oxide.
There are a total of 64 oxygen atoms in 2Ca(NO3)2. This is calculated by multiplying the subscript (in this case, 16 oxygen atoms per formula unit) by the number of formula units given (2).
