Answer:
<em>The solution is 0.450 M. How many mL are needed? </em><em> </em>
<em /><em /><em /><em>-</em><em> </em><em>0.667 mL</em>
Explanation:
N(Ca)/2 = n(O)/1 = n(CaO)/2
The calcium and the Calcium Oxide are divided by 2 because of their coefficients
there is no number in front of the oxygen so it is over one.
Hope this helped!!
Answer:
1.4063 moles of oxygen are required
Explanation:
Based on the chemical equation:
4Al + 3O₂ → 2Al₂O₃
<em>4 moles of aluminium react with 3 moles of oxygen.</em>
<em />
To solve this question we need to convert the moles of aluminium to moles of oxygen using the chemical reaction:
1.875 moles Al * (3 moles O₂ / 4 moles Al) =
<h3>1.4063 moles of oxygen are required</h3>
