Why is lead(II) nitrate: “Pb(NO3)2” and not “Pb3NO2”? Just a bit confused because it looks a bit funny compared to how I learned how to write compounds.

Explanation:

this is because the combining capacity, ie valency, of Pb is 2 of which NO3 is 1. So, when they will combine by cross method, the compound become Pb(NO3)2 (lead II nitrate).

hope this helps you.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

answer: mole of the gas
