The mass of solid mg used in the lab to reduce the copper ions is in excess of the minimum required. what happens to the unused (excess) mg (s)?

massxgravity x heght=weightxheight= pe

4900=490xh

h=10

the rearrangement of particles in a physical change. hope this

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
