I think the answer is 4.)Cumulonimbus but I'm not 100% sure
The balanced chemical equation for aqueous sodium hydroxide being added to a solution containing lead(II) nitrate and a solid precipitate being formed is :
2 NaOH (aq) + Pb(NO3)₂ (aq) ⇒ Pb(OH)₂ (s) + 2 NaNO₃ (aq)
A balanced chemical equation is the one in which the number of atoms are equal for every element on both the the reactant side as well as the product side. Their charges should also be the same.
A precipitate is a solid mass of some substance that forms up in a liquid solution due to certain chemical reactions. This solid mass does not dissolve in the liquid solution.

Answer:
Definition of Inert. An inert chemical is one that is stable and unreactive under specified conditions. ... However, most of the noble gases have now been observed to form compounds, although generally under unusual conditions. Helium and neon are highly inert; they form no compounds.
Answer:
Double replacement or double decomposition
Explanation:
In the reaction below, a double replacement or double decomposition has occurred.
2Na₃PO₄ + 3CaCl₂ → 6NaCl + Ca₃(PO₄)₂
This reaction occurs mainly between two ionic substances.
The reaction involves an actual exchange of partners to form new compounds. For example;
AB + CD → AD + CB
One of the following conditions below serves as the driving force for double replacement reactions:
- Formation of an insoluble compound or precipitate.
- Formation of water or any other non-ionizing compound
- Liberation of a gaseous product.
Atoms form chemical bonds to make their outer electron shells more stable. ... An ionic bond, where one atom essentially donates an electron to another, forms when one atom becomes stable by losing its outer electrons and the other atoms become stable (usually by filling its valence shell) by gaining the electrons.
