Question

Ca-CaO-CaSO4 ОВР ПИУ,СИУ

Answer 1

Ответ:

Объяснение:

2Ca + O2 = 2CaO

CaO + H2SO4 = CaSO4 + H2O

ПИУ: CaO + 2H⁺ + SO₄²⁻ = CaSO₄↓ + H₂O

СИУ: CaO + 2H⁺ + SO₄²⁻ = CaSO₄↓ + H₂O

Answer 2

It seems like you've provided a sequence of chemical compounds: Ca-CaO-CaSO4. However, the context or specific question is not clear. If you could provide more details or clarify your inquiry, I'd be happy to help you with the information you need.

Based on the compounds given:

1. Ca: Calcium
2. CaO: Calcium oxide (also known as quicklime)
3. CaSO4: Calcium sulfate (often referred to as gypsum)

The terms "ОВР" and "ПИУ,СИУ" are not recognizable in this context, so please provide more information or context for a more specific response.
