Question

Fe=FeCl3=Fe(OH)3=Fe2O3=Ba2(SO4)3​

Answer 1

2Fe + 3Cl2 = 2FeCl3

FeCl3 + 3NaOH = Fe(OH)3 + 3NaCl

2Fe(OH)3 =t Fe2O3 + 3H2O

Fe2O3 + 3H2SO4 = Fe2(SO4)3 + 3H2O

Answer 2

It seems like you've listed a series of chemical compounds and equations involving iron (Fe) and barium sulfate (Ba2(SO4)3). Let's break down each of these compounds and reactions:

1. Fe: This represents the chemical symbol for iron, which is a metallic element commonly found in various minerals and ores.

2. FeCl3: This is ferric chloride, a chemical compound consisting of iron (Fe) and chlorine (Cl) atoms. It's often used as a reagent in various chemical reactions.

3. Fe(OH)3: This is iron(III) hydroxide, also known as ferric hydroxide. It's a compound formed when iron reacts with hydroxide ions (OH-) in a basic solution.

4. Fe2O3: This is iron(III) oxide, also known as ferric oxide or rust. It's a common compound formed when iron reacts with oxygen in the presence of moisture.

5. Ba2(SO4)3: This is barium sulfate, a compound composed of barium (Ba) cations and sulfate (SO4) anions. It's often used as a contrast agent in medical imaging procedures due to its low solubility in water.

It's important to note that your equation "Fe = FeCl3 = Fe(OH)3 = Fe2O3 = Ba2(SO4)3" doesn't accurately represent chemical reactions. Each compound or formula you've listed is a distinct chemical species, and they don't directly convert into each other in a simple way. If you're looking for information about specific reactions or transformations involving these compounds, please provide more details so I can assist you further.
