<u>Given:</u>
Moles of Al = 0.4
Moles of O2 = 0.4
<u>To determine:</u>
Moles of Al2O3 produced
<u>Explanation:</u>
4Al + 3O2 → 2Al2O3
Based on the reaction stoichiometry:
4 moles of Al produces 2 moles of Al2O3
Therefore, 0.4 moles of Al will produce:
0.4 moles Al * 2 moles Al2O3/4 moles Al = 0.2 moles Al2O3
Similarly;
3 moles O2 produces 2 moles Al2O3
0.4 moles of O2 will yield: 0.4 *2/3 = 0.267 moles
Thus Al will be the limiting reactant.
Ans: Maximum moles of Al2O3 = 0.2 moles
Cells are composed of water, inorganic ions<span>, and carbon-containing (organic) molecules. Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass.</span>
Soil is usually layered. The uppermost layer is called topsoil and this layer contains the most humus, plant roots, and living creatures. The middle layer is called subsoil.
153.888 grams are in 4.8 moles of sulfur
2 boxes of A
Because C=A+B
2 of A = 20 grams
at the other hand we have 2 of B =10
So 20 + 10 = 30 grams
