Covalent bonds can be best described as :
neutral atoms coming together to share electrons.
neutral atoms coming together to create electrons.
ionized atoms coming together to trade electrons.
ionized atoms coming together to destroy electrons.

Answer : Option A) Neutral atoms coming together to share electrons.Explanation :

Covalent bonds are those bonds which is formed when the neutral atoms come together and share their electrons to form covalent bonds.

They are also called as molecular bond, in which bonds involves sharing of electrons between both the atoms.

The electron pairs which are involved in bonding are called as shared pairs or bonding pairs, and they also form stable balance of attractive and repulsive forces between atoms during sharing of electrons called as covalent bonding.

neutral atoms coming together to share electrons is the correct answer.

Explanation:

Covalent bonds can be best described as :neutral atoms coming together to share electrons.Covalent bonding is formed when the pairs of electrons are shared via atoms and they are called a molecular bond.Atoms get covalently bond with different atoms to obtain more stability that is obtained by creating a complete electron shell.The electron pairs that are included in bonding are called shared pairs.

Idont know. if you want an answer you need to give us some context dude.

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
