Question

CaO → Ca(OH) 2 → H 2 O → RbOH → Rb 2 SO 4 → CaSO 4 =

Answer 1

Ответ:

Объяснение:

1) СаO + H2O = Ca(OH)2

2) Ca(OH)2 (нагревание) = СаО + Н2О

3) H2O + Rb2O = 2RbOH

4) 2RbOH + H2SO4 = Rb2SO4 + 2H2O

5) Rb2SO4 + CaCl2 = CaSO4 + 2RbCl

Answer 2

It looks like you've provided a sequence of chemical reactions involving different compounds. The reactions you've listed are as follows:

1. CaO (Calcium Oxide) reacts with water (H2O) to form Ca(OH)2 (Calcium Hydroxide).
2. Ca(OH)2 reacts with RbOH (Rubidium Hydroxide) to form Rb2SO4 (Rubidium Sulfate) and CaSO4 (Calcium Sulfate).

However, it's important to note that the sequence of reactions you've presented isn't entirely accurate. The reaction between Ca(OH)2 and RbOH, as well as the formation of Rb2SO4 and CaSO4, doesn't typically occur as described in this sequence.

If you have a specific question about these reactions or if you need more information, please feel free to ask!
