A specific, electrically neutral atom of boron contains a total of 16 particles (protons, neutrons, and electrons). What is the mass number of this atom of boron?

A: 5
B: 6
C: 11
D: 21

A1 a 2 a 3 ooh lol i think that's it

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
