1) Rend the following experimental scenario and fill out the Experimental Design Diagram Below for
the experiment described below.
METALS AND RUSTING TRON: In chemistry class, Allen determined the effectiveness of various
metals in releasing hydrogen gas from hydrochloric acid. Several weeks later, Allen read that a utilities
company was burying lead next to iron pipes to prevent rusting. Allen hypothesized that less rusting
would occur with the more active
metals. He placed the following into four separate beakers of water:
(A) I iron nail, (B) 1 iron nail wrapped with an aluminum strip. (C) I iron nail wrapped with a
magnesium strip.(D) iron nail wrapped with a lead strip.
He used the same amount of water, equal amounts (mass) of metals, and the same type of iron nails. At
the end of 5 days, he rated the amount of rusting as small
, moderate or large. He also recorded the color
of the water
