Answer:
1 mole of aluminum must contain 6.022⋅1023 atoms of aluminium → this is known as Avogadro's constant.
Explanation:
An insect needs mud wallows to breed; that insect pollinates several flowers in that ecosystem.
Mass = moles x molar mass
so mass of 6 moles of h2 is: 6×1×2 = 12g
Answer: I think it’s B

Answer:
Brackett Series (n = 4)
Explanation:
The least energetic line of Hydrogen atom lies in <em>Brackett Series </em>when n = 4 because these are least energetic, have longer wavelengths and lies in Infrared region of spectrum. No traces of <em>Pfund series </em>are formed by H=atoms.
