The kinetic energy of the ball b is 12.3kJ and ball B to a is 14.2kj
Answer:
Heterogenous
Explanation:
Heterozygous mixtures seperate and consist of two or more layers. For example, When oil and water are combined, they do not mix evenly, but instead form two separate layers. They also use filter and can scatter light.
Answer:
Ni^2+
Explanation:
The following data were obtained from the question:
Proton = 28
Electron = 26
Neutron = 34
Next, we shall determine the atomic number of the element.
Atomic number of an element is simply defined as the number of protons in the atom of an element.
Thus,
Atomic number = proton number
Proton = 28
Atomic number = proton number = 28
Atomic number = 28
Therefore, the element is Nickel since no two elements have the same atomic number.
Finally, we shall determine the charge on the Nickel atom as follow:
Proton = 28
Electron = 26
Charge on atom =
Charge on atom = Proton – Electron
Charge on atom = 28 – 26
Charge on atom = +2
Therefore, we can represent the Particle as Ni^2+
In the Lewis structure of PO43- there are a total of 32 valence electrons. For the Lewis structure for PO4 3- you should take formal charges into account to find the best Lewis structure for the molecule. Remember, PO4 3- has a negative three charge on the molecule.
Answer:
no
Explanation:
because it will need more energy to move from 5th to 3rd than 4th to 2nd since it is closer to the nucleus
