Answer : The density of the metal will be 10.08g/cm^3

Explanation :

Density : It is defined as the mass of a substance contained per unit volume.

Formula used :

Density=\frac{Mass}{Volume}

Given:

Mass of metal = 126.0 g

Volume of metal = 12.5cm^3

Now put all the given values in the above formula, we get:

Density=\frac{126.0g}{12.5cm^3}=10.08g/cm^3

Thus, the density of the metal will be 10.08g/cm^3

Density is defined as mass/volume (or m/v).

So,

(126.0 g)/(12.5 cm^3)= 10.08 g/cm^3

If your teacher requires correct significant figures, the answer is 10.1 g/cm^3.
If not, the first answer is fine.

58. Explain why each successive ionization of an electron
ale4655 [162]

Answer:

It's because removal of electron from an atom, reduces the size of an atom.

Explanation:

When an electron is removed from an atom, it becomes an ion and in this case it will become a postive ion.

When an electron is removed from an atom, the charge balance of an atom is disturbed and positive charge increases in comparison to the negative charge. This results in increase nuclear (positive) charge which exerts greater attraction on the remaining electrons and as a result the remaining electrons are more strongly attracted by the nucleus and in this way the atomic size is decreased. Due to this increased nuclear attraction and reduced atomic size, it bcomes difficult to remove more electeon from the positively charged ion of reduced size. This is the reason that each successive ionization of electron requires a greater amount of energy.

The ionization energy has inverse relation with the size or radius of an atom. This also justifies the reason that why each successive ionization of an electron requires greater amount of energy.

this shows that magnesium is higher in the reactivity series than lead.

I don't think there can be an ionic equation written because both components are in solid form and neither is in an aqeuos state.
