Pseudophryne. The corroboree frog is incredibly distinctive with its bright yellow and black striped skin. The upper surface has a rough texture whilst the belly is smooth and either black and yellow or black and white.Females are larger in size than males and, unusually, neither sex has webbed toes.seudophryne.

(b) P4 is non polar covalent. (c) BF3 is non polar covalent molecule (individual B-F bonds are polar but the net dipole moment is zero due to its triangular planar geometry).b) P4 is non polar covalent.

Best Answer: H3PO4 is phosphoric acid PO4(-3) is the phosphate ion.. with P in the +5 ionization state HPO4(-2) is hydrogen phosphate ion H2PO4(-1) is dihydrogen phosphate ion PO4(-2) is certainly NOT a phosphate ion.The P would be in a +6 oxidation state. which would mean instead of this electronic configuration as in phosphate..hosphate is NOT PO4(-2) but these three ions are discussed in biochem PO4(-3) HPO4(-2) H2PO4(-1).
