Answer:Seeds are great sources of fiber. They also contain healthy monounsaturated fats, polyunsaturated fats and many important vitamins, minerals and antioxidants. When consumed as part of a healthy diet, seeds can help reduce blood sugar, cholesterol and blood pressure
Explanation:
Consider this reaction : 2Al2O3 → 4Al + 3O2
<em>The number of moles of Al2O3 can be determined from its mass →</em>
<em>Number of moles of AL2O3 = mass/molar mass</em>
=51/(27x2+16x3)
= 0.5 mol
Now, calculate aluminium's number of moles from the mole ratio →
<em>Mole ratio</em> 4(Al) : 2(Al2O3)
<em>Number of moles of Al</em> = (4/2) x0.5mol = 1 mol
<em>Mass</em> of Al = number of moles x molar mass
= 1x27
= 27kg <em>(theoretical yield)</em>
<em>Given, actual yield</em> = 17kg
<em>Therefore, percentage yield</em> = (actual yield / theoretical yield ) x 100
= (17/27)x100
= 62.96%
