Answer 1

C = Carbon

H = Hydrogen

N = Nitrogen

O = Oxygen

(If NO2 it is nitrite.. if NO3 it is nitrate)

P = Phosphorus

S = Sulfur

Ca = Calcium

Answer 2

CHNOPSCa is the chemical formula representing the elements commonly found in living organisms: Carbon (C), Hydrogen (H), Nitrogen (N), Oxygen (O), Phosphorus (P), Sulfur (S), and Calcium (Ca). These elements play crucial roles in the structure and function of biological molecules.
