If X is Ni, then what metal choices can you have for Y? (Refer to Standard reduction potential chart) Based on your choice of metal Y, suggest appropriate electrolyte, and salt bridge solution for the cell. Explain your Justification

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 yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
