Answer:
Exothermic
Explanation:
Exothermic describes a process or reaction that releases energy
Answer:
0.132 meters is the wavelength of sounds to which people are most sensitive.
Explanation:
Frequency of the sound human ears are most sensitive to = 
Speed of the sound wave = S = 330 m/s
Wavelength of the sound human ears are most sensitive to = 
0.132 meters is the wavelength of sounds to which people are most sensitive.
#2 reactivity is the answer
Answer is:
18 electrons.
<span>The principal quantum number (n) is one
of four quantum numbers which are assigned to each electron in an atom to
describe that electron's state.
The azimuthal quantum number (l) is a quantum number for
an atomic orbital that determines its orbital angular
momentum and describes the shape of the orbital, l = 0....n-1.</span>
<span>For n = 3, l = 0, 1, 2.</span>
<span>l = 0, s orbital with 2 electron.</span>
<span>l = 1, p orbitals with 6 electrons.</span>
<span>l = 2, d orbitals with 10 electrons.</span>
<span>2 + 6 + 10 = 18 electrons.</span>
