Answer:
Energy required to remove an electron from the atom.
Explanation:
Energy required to remove an electron from an atom describe ionization energy because in chemistry, ionization energy in is the amount of energy needed to remove electrons from the atoms or ions of chemical species.
Ionization energy increases as we move across the period of elements in the group and this is because electrons are bond tighter by high effective nuclear charge and ionization energy of elements increases down the group because electrons are bond together in lower energy orbitals.
Answer is <span>
Ni²</span>⁺(aq)
+ 6NH₃(aq)
⇌ [Ni(NH₃)₆]²⁺<span>
</span>
<span>When the concentration of Ni²⁺</span><span>(aq) increases, according to the Le Chatelier’s principle
system tries to become equilibrium by reducing the increased factor. To do
that, the concentration of Ni²⁺</span><span>(aq) should be reduced. Hence, the forward reacted should be
promoted to reduce the Ni²⁺</span><span>(aq) concentration</span>.
When you litter,
the trash can go into the ocean, and a fish could think of it as food, eat it, suffocate and die,
Same thing for land (but no ocean)
The answers is 3.0 g/cm^3
Explanation:
You use the formula
Density= mass/volume
When they give you mass and volume.
The mass is 15 grams and the volume would be 5 cm^3.
So the density would be
15/5= 3
