Question

FeI2-I2-HI-CaI2-AgI​

Answer 1

Ответ:

Объяснение:

FeI2 = Fe + I2

I2 + H2 = 2HI

2HI + CaCl2 = CaI2 + 2HCl

CaI2 + 2AgNO3 = 2AgI + Ca(NO3)2

Answer 2

The given sequence "FeI2-I2-HI-CaI2-AgI" appears to be a combination of chemical symbols and formulas. Each part represents a compound or element. Let's break it down:

1. FeI2: This represents iron (II) iodide, which is a compound consisting of iron (Fe) and iodine (I).

2. I2: This indicates molecular iodine, a diatomic molecule composed of two iodine atoms.

3. HI: This stands for hydroiodic acid, which is a strong acid formed by hydrogen (H) and iodine (I).

4. CaI2: This represents calcium iodide, a compound composed of calcium (Ca) and iodine (I).

5. AgI: This indicates silver iodide, a compound formed by silver (Ag) and iodine (I).

So, the complete sequence can be interpreted as:

Iron (II) iodide - Molecular iodine - Hydroiodic acid - Calcium iodide - Silver iodide
