Re: Estimation of the amount of heat generated by the cell
Hello, I think to estimate the amount of heat generated by the fuel cell, you can use the relationship between the change in enthalpy (∆H) and the number of moles of water produced (n): ∆H = -n * ∆Hf Where ∆Hf is the molar enthalpy of formation of water (-286 kJ/mol). First, convert the given ∆H val...

Re: zinc acetate dihydrate+tea polyphenols→ZnO NPs
I think the correct balanced equation for the reaction between zinc acetate dihydrate (Zn(CH3COO)2·2H2O) and tea polyphenols (C22H18O11) would be: Zn(CH3COO)2·2H2O + C22H18O11 → Zn(OH)2 + 2CH3COOH + H2O In this equation, zinc acetate dihydrate and tea polyphenols react to form zinc hydroxide, acetic...
