Explanation:
The answer is the Calcium ion. It satisfies the conditions of the question.
Condition 1
The net ionic charge is one-tenth the nuclear charge.
In the Calcium ion, Ca²⁺. The nuclear charge in this ion is 20. The net ionic charge is 2.
2 / 20 = 1 / 10. So the net ionic charge is indeed one tenth of the nuclear charge.
Condition 2
The number of neutrons is four more than the number of electrons.
Mass Number of Ca²⁺ = 44
Atomic Number = 20
Neutrons = Mass Number - Atomic Number = 44 -20 = 24
Number of electrons = 20 - 2 = 18
Since Number of Neutrons = 22, Number of electrons = 18. This condition also holds.
As an ion and as an isotope = Ca²⁺, Ca - 42
Answer:
soapy water is not good for plants irrigation that is what I learn
I think the correct answer from the choices listed above is option A. It is by the process of photosynthesis that would help counteract with human interactions. The carbon dioxide emitted by human activities can be used by this process to produce more oxygen.
Hey there!:
Molar mass N₂ = 28.0134 g/mol
28.0134 g ------------------- 22.4 L (at STP )
mass N₂ -------------------- 50.0 L
mass N₂ = 50.0 x 28.0134 / 22.4
mass N₂ = 1400.67 / 22.4
mass N₂ = 62.529 g
Hope this helps!
