I did a lab about measuring a enthalpy shift after dual reactants were churned together. i’m confused about how to heed in between pointless as well as one after another errors. i assimilate which one after another errors in initial observations customarily come from a measuring instruments or when a experimenter uses a instrument improperly.

however, does this have to be a instrument used to pick up a data, or only any apparatus used in a experiment?

one of a weaknesses i wish to plead is a unconstant stirring. i influenced a reactants during a greeting with a potion rod…i theory i was arrange of regulating a hang improperly since i wasn’t stirring during a "constant" speed…is this a one after another or pointless error?

how about if a little of a powder i used in a examination was excluded? similar to it was stranded upon a weighing vessel so it wasn’t combined to a resolution as well as a little of it feel upon a beaker’s insulator?

thanks
some of it fell*
