Interpretation :
The reason for the water formation reaction from hydrogen and oxygen to not be balanced must be explained. A picture of the balanced equation must be drawn.
Concept Introduction :
2 moles of hydrogen reacts with 1 mole of oxygen to produce 2 moles of water.

Answer to Problem 32A
The reaction is not balanced as there are 2 O and 2 H atoms in the reactant side whereas in product side there are 2 H and 1 O atom.
A picture of the balanced equation is drawn.
Explanation of Solution
In the unbalanced equation the number of oxygen was not the same in both the sides of the equation. To balance it 2 moles of hydrogen are taken and 2 moles of water is produced.
As shown in the picture 2 moles hydrogen has reacted with 1 mole of oxygen to produce 2 moles of water.

- Another standard reference electrode is the standard calomel electrode: Hg2Cl2(s) (calomel) + 2e2 Hg() +2 Cl(aq) This electrode is usually constructed with saturated KCI to keep the Cl- concentration constant (similar to what we discussed with the Ag-AgCl electrode). Under these conditions the potential of this half-cell is 0.241 V. A measurement was taken by dipping a Cu wire and a saturated calomel electrode into a CuSO4 solution: saturated calomel electrode potentiometer copper wire CuSO4 a) Write the half reaction for the Cu electrode. b) Write the Nernst equation for the Cu electrode, which will include [Cu2+] c) If the voltage on the potentiometer reads 0.068 V, solve for [Cu²+].arrow_forward2. (Part B). Identify a sequence of FGI that prepares the Synthesis Target 2,4-dimethoxy- pentane. All carbons in the Synthesis Target must start as carbons in either ethyne, propyne or methanol. Hint: use your analysis of Product carbons' origins (Part A) to identify possible structure(s) of a precursor that can be converted to the Synthesis Target using one FGI. All carbons in the Synthesis Target must start as carbons in one of the three compounds below. H = -H H = -Me ethyne propyne Synthesis Target 2,4-dimethoxypentane MeOH methanol OMe OMe MeO.
