Question

Evaluate the procedure used in this experiment by considering the properties used to identify the unknowns and the number of knowns that were tested. Revise the experimental design by proposing ways to modify the experiment to increase your certainty in the identity of the unknowns

Answer 1

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 color, malleability, melting points, and to test how shiny or dull it is. I would propose these to increase the certainty 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.
