Why is the following not a redox reaction? Is it because it forms a solid? What are the charges for each? *I got this wrong in an exam just want to understand why.
Co(C2H3O2)2(aq) +2KOH(aq) ---> Co(OH)2 (s) + 2KC2H3O2 (aq)
The mass of the water in the inner bath is 1.60×10^3 g . The temperature of the calorimeter and its contents rises 2.84K as a result of this reaction. 1)Calculate the calorimeter constant.
why we call benzene phenyl and not benzyle when one hydrogen is removed because in case of alkanes we name them alkyl on the removal of one hydrogen atom.
Change in heat content We write H = Hfinal - Hinitial or for chemical reactions H = Hproducts - Hreactants Given this equation, What sign is H for exothermic reactions? What sign is H for endothermic reactions?
The mass of the crucible, cover and sample of Ti was 36.383 g. Following the reaction of the Ti metal with Oxygen, the contents of the crucible, cover and reaction mixture was heated to a constant mass of 37.472 g. Determine the mass of the oxide ..
