What is the nature of the p-o bond in phosphorus pentoxide (p2o5)?
a.) nonpolar covalent
b.) moderately polar covalent
c.) highly polar covalent
d.) ionic
e.) polar ionic

"Polar ionic" is the nature of the P-O bond among the choices given in the question that is present in phosphorus pentoxide (P2O5). The correct option among all the options that are given in the question is the last option or option "E". I hope that this is the answer that has come to your help.

The answer is accuracy

Heat capacity = mcδtheat capacity = 2.676×10^3 j ..the heat capacity given is for 7.00 g of kcn,potassium cyanide which is equal to 0. mole of mole = mass  ÷ mr of kcn is 7  ÷ 65 =0.therefore: 0. of kcn liberates 2.676×10^3 j of heat1 mole   (2.676×10^3    ÷  0.107 )  × 1 =do the calculation to obtain 25009 j = 25kj
