Re: Ocr A Chemistry A Evaluative Task Help!!!!for the enthalpy one learn how to calculate the percentage error.... very HIGH CHANCE OF THAT COMING UP
.. DOES ANY ONE KNOW ABOUT THE TITRATION EVALUATIVE?
AND REMEMBER TO WRITE TO THE CORRECT DECIMAL PLACES ,,, IF THE CURRENT DATA IS IN 1.DP IN THE TABLE THEN WHEN FILLING IN THE TABLE USE 1DP... HAVE FUN
OH AND MAKE SURE YOU KNOW WHEN A PLUS OR MINUS SIGN IS NEEDED IN A REACTION FOR EXO OR ENDO THERMIC...
Thanks
