Answer:
118 neutrons
Explanation:
There are three subatomic particles in an atom namely: electron, neutron and proton. The mass number of an atom is calculated by adding the proton no. (atomic mass) + neutron no.
That is;
Mass no. = proton no. + neutron no.
This means that to obtain the neutron no. in the atom of an element, we subtract the no of protons or atomic mass from the mass number.
According to this question, Plutonium-196 is said to have an atomic number of 78. The mass no. is 196, hence, the number of neutrons is:
196 - 78
= 118 neutrons.
For [Ni(en)³]²⁺ which is purple, the crystal field splitting energy is greater than the complex ion, [Ni(H₂O)₆]²⁺ which is green in color.
When a Lewis base id attached to the metal ion by covalent bond, then the complex ion is formed and when these complex ions are present with other ions of opposite charge or neutral charge, they will make complex compounds.
Answer:
Molar masses of X and Z
Explanation:
To determine the mole percent of a mixture ( mole percent of unknown metals = number of mole of each of them divided the total of both the unknown salt × 100) since the percent by mass is know; we the molar mass of X and Z
mole = mass given / molar mass
When a conductor is passed through a magnetic field, a current is induced in the conductor. This phenomenon is called electromagnetic induction. A changing magnetic field creates an electric field or current. This happens because of the movement of electrons in conductor as affected by the presence of the changing magnetic field.
