Question

Can you please help me with thse science questions?

1. An example of a characteristic property is

a. size

b. chemical activity

c. amount

d. shape

2. True/False....If it is false, change the all-capital-letters word to make it true.

Useful amounts of copper can be isolated during a process called ELECTROLYSIS.

Answer 1

1) b.

a, c, d are not characteristics of one material because any material can be put into shape, put into a certain amount, or put into a particular size.

2) Copper can be isolated using electrolysis, so true.  The process would be to put copper that is with something into a solution, with another receiver, then pass the electric current through the coppermixed material, into the solution and to the other receiver.  This then causes the dissolution of the copper from the source into solution, then onto the receiver.
