Question

write equation for heated iron react with both chlorine gas and hydrogen chloride gas?

Answer 1

Answer:

An alternative system for naming compounds containing metals that form only two ions is sometimes seen, especially in older literature. The ion with the higher charge has a name ending in -ic, and the one with the lower charge has the suffix -ous. For example, Fe3+ is called the ferric ion, and Fe2+ is called the ferrous ion. The names for FeCl3 and FeCl2 are then ferric chloride and ferrous chloride, respectively.

As we said, chlo­rine is heav­ier than air, so for the ex­per­i­ment it can be stored in an open flask. The re­ac­tion takes place with iron heat­ed up to 200 de­grees, so the rod should be heat­ed with the burn­er. Then low­er the rod into the green­ish gas, and ob­serve an im­me­di­ate vi­o­lent re­ac­tion: the chlo­rine ox­i­dizes the iron to a triva­lent state. The re­ac­tion is ac­com­pa­nied by the re­lease of tox­ic brown fumes, and crys­tals of iron chlo­ride start to form in the flask:

2Fe + 3Cl₂ = 2Fe­Cl₃

Answer 2

Question ;

Write equation for heated iron react with both chlorine gas and hydrogen chloride gas?

Answer:

Iron reacts with Cl₂ gas in 2 ways ;

2 Fe + 3 Cl₂ ( g )  = 2 FeCl₃

The enthalpy of reaction is negative ,

So it is exothermic reaction .

Fe +  ( 3 / 2 ) Cl₂( g ) = FeCl₃

The enthalpy of recation is negative ,

So , it is exothermic  reaction .

The reaction of iron and HCl produces FeCl₂ and Hydrogen gas

Fe (s) + 2 HCl ( aq ) = FeCl₂( aq ) + H₂  ( g )

This is with HCl gas .

Thus we get answer .
