I.         Objective(s): To determine the dissolve points of 2 unknown compounds. II.         Procedure: 1) habilitate a small quantity of unknown A in a capillary tube. 2) Setup                                 3) Place into the hot water.                                 4) delay till chemical substance melts.                                 5) Lift clamp unwrap of water.                                 6) magnetic disc the temperature at which it crystallizes.                                 7) Repeat for 3 great values.                                 8) Repeat 1-7 for chemical B. III. Results:                                 A                         B Melting Points (C):         1) 70.1                 1) 60.8                                 2) 70.3                 2) 70.8                                 3) 72.6                 3) 71.4 add up:                         71                         67.7 VI. hallucination Analysis: 1) One problem we had was estimating the temperature of the melting point because we werent quick enough to read it forrader it started to cool smooth. 2) We had difficulties attempt to tie the little tube to the .7                                 72.6 - 7! 1                 1.6 Chemical B                 x         x                 x-x                                 60.8 -         67.7                 6.9                                 70.8 -         67.

It took a pot of time and patience to do that. 3) Chemical A Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â X Â Â Â Â Â Â Â Â X Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â X-X Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 70.1 - Â Â Â Â Â Â Â Â 71 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â .9 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â 70.3 - Â Â Â Â Â Â Â Â 71 Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â If you want to get a full essay, order it on our websi te:
