Answer:
limiting reactant started with/limiting reactant needed=
= 3.5 mol/3.5 mol=1:1
Explanation:
2H2 + 1 O2 ---> 2 H2O
from reaction 2 mol 1 mol
given 3.5 mol 2.5 mol
needed 3.5 mol 1.75 mol
Excess reactant O2, Limiting reactant H2.
Limiting reactant will be used completely.
So, limiting reactant started with/limiting reactant needed=
= 3.5 mol/3.5 mol=1:1
Answer:
False
Explanation:
The electrons are excited because:
1.- They posses more energy than the basal form, but this doesn´t mean that they can easily react, remember, the electrons are the outside part of an atom.
2.- By the time, this electrons are loosing their energy, that mean that they return to the basal form.
