covalent bonds can be best described as

a. neutral atoms coming together to share electrons.

b. neutral atoms coming together to create electrons.

c. ionized atoms coming together to trade electrons.

d. ionized atoms coming together to destroy electrons.

Covalent bonds are described as the neutral atoms coming together to share electrons.

Explanation:

Covalent bond is defined as the bond which is formed by the sharing of electrons between the atoms forming a compound. These are usually formed when two non-metals react.

For Example:  HCl is formed by the combination of hydrogen and chlorine atoms. These atoms share electrons to form the compound.

Ionic bond is defined as the bond which is formed by complete transfer of electrons from one atom to another atom.

The atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom. This bond is usually formed between a metal (carrying positive charge) and a non-metal (carrying negative charge)

For Example:  NaCl is formed by the combination of ions

Hence, covalent bonds are described as the neutral atoms coming together to share electrons.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
