Railroad maintenance initiates the reaction of 4.0 mol Al and 2.0 mol Fe2O3 to connect two lengths of rail. What is the heat chance during the reaction?

 

 

 

Enter either a + or - sign AND the magnitude.

 

______________

Over the years, the thermite reaction has been used for welding railroad rails, in incendiary bombs, and to ignite solid fuel rocket motors. The reaction is

Fe₂O₃(s) + 2Al(s) → 2Fe(l) + Al₂O₃(s)

Watch the video to see the reaction.

What mass of iron(III) oxide must be used to produce 45.02 g of iron?

g

The reactive intermediate that initiates the reaction inFriedel-Crafts reactions is called a(n)

a. carbanion
b. carbocation
c. nitroniumion

d. acylium ion

I'm asking again because I found a torn response. Some peoplesaid B.carbocation and some responded D.acylium ion

This question is in response to a acylation reaction pleasehelp!
