Inefficiency of the material or engine causes the output work of a machine to be less
than the input work. It is governed by the second law of thermodynamics wherein
no product of work can produce 100 percent efficiency. Only the Carnot engine
can produce a 100 percent effieciency.
By convention, elements are organized in the periodic table, a structure that captures important patterns in their behavior.

I would say voting. I hope that helped or just report my comment.
Explanation:
The amount of Al that would be needed will be 0.79 grams
<h3>Stoichiometric calculations</h3>
From the equation of the reaction below:
The mole ratio of Al to 
is 2:3.
Mole of 71.8 mL. 0.610 M = 0.610 x 71.8/1000 = 0.0438 moles
Equivalent mole of Al = 2/3 x 0.0438 = 0.029 moles
Mass of o.o29 moles Al = 0.029 x 26.98 = 0.79 grams
