Answer:
Excited State
Explanation:
It's when electrons absorb energy and move to a higher level.
Answer:
Likely 
(indium.)
Explanation:
Number of atoms: 
.
Dividing, 
, the number of atoms by the Avogadro constant, 
, would give the number of moles of atoms in this sample:
.
The mass of that many atom is 
. Estimate the average mass of one mole of atoms in this sample:
.
The average mass of one mole of atoms of an element (
in this example) is numerically equal to the average atomic mass of that element. Refer to a modern periodic table and look for the element with average atomic mass 
. Indium, , is the closest match.
Answer:
It has hollow bones and jaws.
Explanation:
The cladogram shows that Species C has both hollow bones and Jaws. Species A has hollow bones while species B has Jaws. The cladograms shows that species C has both the characteristics.
Answer:
Cl
Explanation:
n for Mg=m:Mm
=65.8:24
=2.74mol
n for Cl=m:Mm
=45.7:70
=0.65mol
According to the <em>number of moles</em> we can say that the limiting reagent is Cl as it has few moles.
