You have 20.0 grams of Pb(NO3)2. You put it in water and bring the
final volume to 50.0 mL. What is the Molarity?

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

b) mutualism

hope this : )

the answer is 1 i believe

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
