Question

ca(oh)₂ + h₂so₄ → caso₄ + 2h₂o
synthesis
decomposition
single displacement
double displacement
conbustion

Explanation:

A double displacement reaction involves the exchange of ions between two compounds. In the given reaction \(Ca(OH)_2 + H_2SO_4 \to CaSO_4 + 2H_2O\), the \(Ca^{2+}\) from \(Ca(OH)_2\) combines with \(SO_4^{2 -}\) from \(H_2SO_4\) to form \(CaSO_4\), and \(H^+\) from \(H_2SO_4\) combines with \(OH^-\) from \(Ca(OH)_2\) to form \(H_2O\). This is characteristic of a double displacement reaction.

Answer:

Double Displacement
