How much energy (kJ) is required to change 5.2 mole of ice (s) at -25 C to water (l) at 0 C?

d.) circle motion requires a force to give it a centripetal acceleration.

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

the answer is c. nacl

bcde is the incorrect answer it is a
