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:
<em>Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.</em>
Answer:
Here
Explanation:
When the atom absorbs energy, it can move to a higher energy state, or excited state. Under what circumstances can an atom emit a photon? A photon is emitted when an atom moves from an excited state to its ground state or to a lower-energy excited state.
