We will take that molar mass of Pb(CO3)2 represents the total mass of all particles in this compound, ie it has value 100%.
M(Pb(CO3)2) = Ar(Pb) + 2xAr(C) + 6xAr(O) = 207.2 + 2x12 + 6x16= 327.2 g/mol
M(Pb) = 207.2 g/mol
From the date above we can set the following ratio:
M(Pb(CO3)2) : M(Pb) = 100% : x
327.2 : 207.2 = 100 :x
x = 63.33% of Pb there is in <span>Pb(Co3)2</span>

Answer:
producers
Explanation:
Producers are the first in the food chain, and include plants. After that, there is herbivores(animals that eat plants), primary consumers(the first consumers in the food chain that eat herbivores), secondary consumers(2nd consumers in the food chain that eat primary), tertiary(3rd consumers that eat secondary), and so on.
