Answer #1

ANS IS WHEN BOB WAS TRANSFERRING HIS REACTION MIXTURE FROM ONE CONTAINER TO OTHER, HE ACCEDENTALLY SPILLED ABOUT HALF OF HIS REACTION ON THE LAB BENCH, AND HE WAS UNABLE TO RECOVER IT.

THE 2nd OPTION IS NOT POSSIBLE BECOUSE IF THE PRODUCT IS NOT DRIED PROPERLY THE % OF YIELD WILL BE HIGH.
