Diagram of the nuclear composition, electron configuration, chemical data, and valence orbitals of an atom of neodymium-144 (atomic number: 60), an isotope of this element. The nucleus consists of 60 protons (red) and 84 neutrons (orange). 60 electrons (white) successively occupy available electron shells (rings).
That will be regarding the water cycle. Write about the importance of the water cycle, each state from evaporation, condensation, precipitation, and run off. How the water cycle affects weather, animals, and the environment.
1.8 L
<h3>
Explanation</h3>
The volume of a gas, V, is inversely proportional to the pressure on it, P. That is:
V₁ · T₁ = V₂ · T₂.
Rearranging gives:
V₂ = V₁ · T₁ / T₂ = 4.2 × (101 / 235) = 1.8 L
Answer:
32.73%
Explanation:
To solve this problem, first find the molar mass of Al(OH)₃.2H₂O
Atomic mass of Al = 27g/mol
O = 16g/mol
H = 1g/mol
Molar mass = 27 + 3(16 + 1) + 2(2(1) + 16)
= 27 + 51 + 36
= 114g/mol
Percentage composition = 
x 100 = 32.73%
