How many grams of C are required to react with 32.1 g of Fe2O3?

3.62 g of C are required

Explanation:

In order to determine the grams of C, in the reaction we have to define it:

Reactants are C and Fe₂O₃

The reaction is:

3C(s) + 2Fe₂O₃(g) → 4Fe(s) + 3CO₂(g)             It is a redox reaction.

We convert the mass of the oxide to moles:

32.1 g . 1 mol/ 159.7g = 0.201 moles

In the reactant side we say:

2 moles of oxide need 3 moles of C to react

Therefore 0.201 moles of oxide must need (0.201 . 3) / 2 = 0.3015 moles of C

We convert the moles to mass → 0.3015 mol . 12 g / 1 mol = 3.62 g

the answer is: they rebelled against saddam hussein’s rule.

kurds opposed saddam rule and wanted independence. kurds in the north and shiites in the south revolt against hussein.

for example, the halabja attack in 1988 conducted against the kurdish people by the iraqi regime under saddam hussein, where between 4000 people are killed and around 9000 are injured.
