Which of the following represents the ground state electron configuration for the Mn3+ ion? (Atomic number Mn = 25) 1s2 2s22p6 3
V125BC [204]

Answer:

1s^22s^22p^63s^23p^63d^{4}

Explanation:

Manganese is the element of group 7 and forth period. The atomic number of Manganese is 25 and the symbol of the element is Mn.

The electronic configuration of the element, manganese is -  

1s^22s^22p^63s^23p^63d^{5}4s^2

To form Mn^{3+}, it will lose 3 electrons from the valence electrons and thus the configuration of the ion is:-

1s^22s^22p^63s^23p^63d^{4}

How many moles of carbon atoms are combined with 11.2 moles of hydrogen atoms in a sample of the compound, C3H8?
lozanna [386]
The compound with a chemical formula of C₃H₈ is propane. The subscripts actually represent the number of the individual atoms in 1 particle of the compound. Since there are the same number of atoms per mole of any substance, the subscript can also represent the moles. Through stoichiometric calculations, the solution is as follows:

Moles of Carbon = 11.2 moles H * 3 mol C/8 mol H = <em>4.2 moles</em>

The ionization constant for water (kw) is 9.311 × 10−14 at 60 °c. calculate [h3o+], [oh−], ph, and poh for pure water at 60 °c.
Sonbull [250]

As,

Kw = [H+] [OH-]

For water, [H+] = [OH-]

Therefore we can write

Kw = [H+]²

9.311 × 10-14 = [H+]²

[H+] = 3.04 × 10-7 = [OH-]

Ph = - log [H+]

= - log ( 3.04 × 10-7)

= 6.52

Thus, Ph = PoH = 6.52
