The balanced chemical reaction is:
4Al + 3O2 = 2Al2O3
We are given the amount of reactants to be used for the reaction. These amounts will be the starting point for the calculations. The mole ratio of the reactant is 4:3. Therefore, the limiting reactant is aluminum.
1.60 mol Al ( 2 mol Al2O3 / 4 mol Al ) = 0.8 mol Al2O3
Answer:
Antigens (more info below)
Explanation:
Antigens determine the blood type and may be either proteins or sugar molecule complexes (polysaccharides). Genes in the blood group antigen group provide instructions for the production of antigen proteins. Blood group antigen proteins serve a variety of functions within the red blood cell membrane.
hope I helped!
Follow the formula.. there’s not enough in this question for me to solve
Answer:
C. At some point, the land was covered in water.
Explanation:
In the diagram it shows the different fossil layers. In the bottom layers there are shells, but as you go up the fossils start changing. This shows that there used to be water there, but now it is land.
Answer:
10 moles of S₈
320 moles O₂
Explanation:
The balanced equation is:
Now we can convert moles of SO₈ (the product) into moles of each reactant, using the <em>stoichiometric coefficients of the balanced reaction</em>:
- 80 mol SO₈ *
= 10 mol S₈
- 80 mol SO₈ *
= 320 mol O₂
In order for 80 moles of SO₈ to be produced, 10 moles of S₈ need to react with 320 moles of O₂.
