Answer» The equation for heat isQ=m(tf−ti)CPQ = heat in Joulesm = mass in gramstf = final tempti = INITIAL tempCp = Specific Heat CapacityFor this PROBLEMQ=???m=275gtf=38.4oCti=85.2oCCp=4.18jgoCQ=275g(38.4oC−85.2oC)4.18JgoCQ=275g(−46.8oC))4.18JgoCQ=−53,796.6JThe negative Joule value means heat is being lost in an exothermic reaction.Explanation:make me brainlist please give me some THANKS I |
