A student reacts 13 moles of iron with 21 moles of oxygen according to the following equation: 4Fe(s) + 3O2(g) +2Fe2O3(s)
How many moles of iron(III) oxide will the reaction produce?

a
34 moles
b
13 moles
c
6.5 moles
d
44 moles

The dispersed phase is liquid and dispersed medium in milk is liquid

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
