We calculate for the amount of chromium metal in the reactant by,
= 350 x (mass of Cr2/mass of Cr2O3)
= 350 x (104/152)
= 239.47 grams
The amount of Cr metal in the product is only 213.2 grams. Thus, the percent yield.
percent yield = (213.2 grams/239.47) x 100%
= 89%
THAT IS TOUGH GIRL HOPE YOU FIND THE ANSWER
4) their metallic properties increase and their atomic radii increase.
When something compresses, it means that the molecules within it suddenly came really close to one another.
