They form the four plant life cycles (check the Nitrogen cycle, Carbon cycle etc...). Nitrogen, Carbon and Phosphorus are non-metalic elements. Water is a molecular compound of oxygen and hydrogen.

Ca+2 combines with PO4-3in the formula Ca3(PO4)2, calcium biphosphate\n\nCaHPO4 is another compound you may be referring to. Calcium hydrogen phosphate or calcium biphosphate

1) is false, all the elements in living things can be found in non-living things\n\n2) this more tricky, what are these 4 elements most common in plants? I'm guessing: Hydrogen and Oxygen, (from water) Carbon, and . . .nitrogen???\nall these can be found in animals\nare you sure the question is asking about elements? elements in living things are pretty common to another. Its the compounds (hemoglobin, chlorophyll, etc) that get rather unique\n\ndo a little research, if some one cannot explain how they got the answer to a T/F question, you can't be sure they are just guessing

in H3P04 u need the oxidation number of what? all these elements have different oxidation numbers in different compounds. the procedure for u to find out the oxidation number is .... if u want the oxidation number of P then write there as x, for H as u know it is +1, for O it is -2.\n then, (+1*3)+(x*1)+(-2*4)=0; 3+x-8=0; x=5 thus, the oxidation number of P in H3P04 is 5.\nin the same way, in H2O2; O is -1\nSi(OH)4 ; Si is x+(4*-2)+4=0; x=4\nin KH2PO4, P is  +1+(+1*2)+x+(-2*4)=0; x=5\nin Fe(HCO3)2 if Fe is +2, H is +1, O is -2 then C is \n+2+2+2x-12=0; x=4\nCu2CrO4, Cu is +2, O is -2 and Cr is 4+x-8=0; x=4\nKMnO4, K is +2, O is -2 and Mn is +2+x-8=0 x=6\nN03, Ois -2, x+(-2*3)=0, x=6\nin HN03, H is +1, O is -2,then N is +1+x-6=0, x=5\nBeH2, H is +2\n\nany doubts u can ask again.

I think FePO4 +O2 >>>>> Fe2O3 + PO2. balance it and solve it . n its simple stoichiometry.

Hypophosphoric acid, H4P2O6, is a tetra basic acid, prepared from NaClO2 and red phosphorous. As to its structure, I don't know, but just try arranging all the atoms in that compound in such a way as to satisfy all their valencies.

Phosphorus, in its common form, is a waxy white (or yellowish) solid that has a characteristic, disagreeable smell similar to that of garlic. Pure forms of the element are colorless and transparent. This nonmetal is not soluble in water, but is soluble in carbon disulfide. Pure phosphorus ignites spontaneously in air, burning to produce phosphorus pentoxide.

I believe the answer is Osmium. He is asking for number of neutrons, not number of protons. Take the atomic mass, (Os = 190.23) And subtract the number of protons it has (Os = 76), giving you an answer of 114.

Elements:\n\nMain constituents are H, C, O, N, with considerable amounts of Ca, Na, P, S, Cl, less Mg, K, Fe, I, and traces of about any common element.\n\nThe most common simple molecule is water.\n\nMost important "inorganic" compounds are CaCO3 (in the bones), NaCl (dissolved in the water) and Ca2(PO4)OH in the teeth.\n\nThe main classes of chemicals are carbohydrates and proteins, which form the main structural elements of our cells as well as most of the functional framework. (DNA for instance has a modified carbohydrate linked by phosphate as its structural basis). Fats (triglycerides of fatty acids) are abundant, but don't participate structurally in most features of human anatomy except as fillers (lower skin, lips, breasts...)
