What is the net ionic equation for the reaction that is represented by the following total ionic equation?
6na+2po2- +3ca2+ +601-
6na+ +6c1+ca3(po4)2
2na3po4 +3cacl2 > 6nacl+ca3(po4)2
2p03-3ca2+_ ca3(po4)2
2p02-+3ca2++601- 6na+ + ca3(po4)2
2p5+ +802-+3ca2+ - caz(po4)2

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
