The number of moles of aluminium that are needed to react completely with 13.2 moles of FeO is 8.8 moles
calculation
2Al + 3FeO → 3aFe +Al2O3
by use of of mole ratio of Al: FeO from equation above = 2:3 the moles of Al is therefore
= 13.2 x 2/3=8.8 moles of Al
Answer:

THE EXTRACTION OF METALS FROM THEIR RESPECTIVE ORES IS KNOWN AS METALLURGY.
THE DIFFERENT PROCESS ARE :- ROASTING, CALCINATION, FROTH FLOTATION AND MGNETIC SEPARATION.
Answer:
Following are the solution to this question:
Explanation:
If the draw a line perpendicular with y-axis thru the diagonal line check but it meets only one curved point, therefore the curve indicates a function not otherwise. They draw a vertical line perpendicular to the y-axis there, it just intersects one more chart point, which is why a graph is a feature:
In point a:
In point b:
Its y-axis length cut also by understanding the benefits of y-interception and the x-axis length gives the x-intercept.

In point C:
Every graph is y-axis symmetric because the left side of the column as well as the middle side of the graph is about the same.
