Evaluate the procedure used in this experiment by considering the properties used to identify the unknowns and the number of kno
xenn [34]

Answer: Hey! its a fellow classmate from K-12! Alright so what I put for the lab report question is :  The properties used to identify the metals were mass, length, and volume. These were the extensive properties that I used. I would propose to test <u>color, malleability, melting points</u>, and to test how shiny or dull it is. I would propose these to increase the <em>certainty</em> in the identity of the metals.  Btw, please mark me brainliest.

Explanation: When it says evaluate It pretty much means " tell me what you used to figure out the identity of the unknown metals".

The part where it says " propose, revise...blah...blah blah means " How could you increase your chance to get the right metal identity, henceforth saying what properties and tools could we use to make this experiment more better; better chances of getting the right identity of metal.
