Given the balanced equation below, calculate the moles of aluminum that are needed to react completely with 13.2 moles of FeO?
irina [24]

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

Determine whether the graph is that of a function by using the vertical-line test. If it is, use the graph to find (a) its domai
Ilia_Sergeevich [38]

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:

\to Domain= [-\pi ,\pi ]\\\\\to Range = [-1,1]

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.  

\to y-intercept = 1\\\\\to x-intercept = \frac{\pi}{2} ,- \frac{\pi}{2} \\\\

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.
