The product of sodium oxalate (NaC2O4) and silver ions (Ag⁺) is silver oxalate (Ag2C2O4), which is a sparingly soluble compound. In solution, two silver ions can react with one oxalate ion to form the precipitate. Sodium ions (Na⁺) remain in the solution as spectator ions. Thus, the overall reaction can be represented as NaC2O4 + 2Ag⁺ → Ag2C2O4 (s) + 2Na⁺.
Th(NO3)4 + 2 H2C2O4-----------Th(C2O4)2 + 4 HNO3 Thorium oxalate is a white powder, toxic, used in the analytical chemistry of thorium and in the technology of thorium separation from other elements.
No, K2SO4 + Na2C2O4 does not undergo a double displacement reaction. A double displacement reaction occurs when ions in two compounds swap places to form two new compounds. In this case, potassium sulfate and sodium oxalate do not swap ions to form new compounds.

Giles Corey was an American farmer involved in the Salem witch trials of 1692. He is notable for being pressed to death with heavy stones for refusing to enter a plea in response to witchcraft charges against him. His steadfastness and tragic end symbolize the injustice of the trials and the extreme measures taken during that period of hysteria. The repetition of "plus" seems to suggest an emphasis or exaggeration, but the context remains focused on Corey's historical significance.
That is 27 x 9 = 243
