WebAnswer: Step 1: The balanced symbol equation is: Zn (s) + CuSO 4 (aq) → ZnSO 4 (aq) + Cu (s) Step 2: Calculate the amount of zinc reacted in moles. Step 3: Calculate the maximum amount of copper that could be formed from the molar ratio: Since the ratio of Zn (s) to Cu (s) is 1:1 a maximum of 0.10 moles can be produced.

The standard cell potential (Ecellꝋ) is Ecellꝋ = (+ 0.80) - (0.00) = + 0.80 V. The Ag + ions are more likely to get reduced than the H + ions as it has a greater Eꝋ value. cooktop backsplash tileWeb1 H NMR chemical shifts relative to TMS H C O H CO HCC l H CBr RCH N H O H C O H N C O N H 2 H O H C H H CN C O H 12 11 10 9 8 7 6 /ppm 543210 O * * * * C C H H O CC 13 C NMR chemical shifts relative to TMS C O O cooktop bcto4pWebThe A-level table takes the mass number to 1 decimal place (GCSE doesn't) and this sheet also includes NMR and IR reference information.
