A solution has a pOH of 8.7 so what is the pH of the solution? Is the solution acidic, basic, or neutral?
RSB [31]
PH + pOH = 14

pH = 14 - pOH

pH = 14 - 8.7

pH = 5,3

This solution is <u>acidic</u>.

If pH<7 - acidic
If pH=7 - neutral
If pH>7 - basic

What is the electrical charge on the nucleus of a carbon-12 atom
Kipish [7]

Answer:

Neutral carbon-12 (or any carbon atom) has 6 electrons with a total negative charge of 6e- orbiting a nucleus with a total positive charge of 6e+, so that the total net charge is zero. The nucleus is made up of 6 protons, each with a positive charge of e+, and 6 neutrons, each with zero charge.

Define ionic bond and explain the formation of nacl and mgo
fomenos

a.

Ionic bond is a bond in which there is complete transfer of valence electrons between atoms.

The atom that loses the valence electron is called the electron donor while the atom that accepts the electron is called the electron acceptor.

Ionic bond usually occurs between metals and non metals.

Ionic bond is a bond in which there is complete transfer of valence electrons between atoms.

b.

The force of attraction between Na⁺ and Cl⁻ forms the ionic bond.

  • In the formation of NaCl, Na has one valence electron in its outermost shell and Cl needs one electron to complete the stable octet configuration.
  • Na donates its valence electron to Cl to form the ionic bond. So, the Na atom becomes positively charged with a charge of +1 while the Cl atom becomes negatively charged with a charge of -1.

Since the atoms are now charged, the force of attraction between them forms the ionic bond.

c.

The force of attraction between Mg²⁺ and O²⁻ forms the ionic bond.

  • In the formation of MgO, Mg has two valence electrons in its outermost shell and O needs two electrons to complete the stable octet configuration.
  • Mg donates its two valence electron to O to form the ionic bond. So, the Mg atom becomes positively charged with a charge of +2 while the O atom becomes negatively charged with a charge of -2.

Since the atoms are now charged, the force of attraction between them forms the ionic bond.
