Determine the energy ratio between the fusion energy that could be liberated in2H 2Hfrom the deuterium in 1.0 kg of seawater and the energy released in the same mass amount of gasoline. You need to know the heat of combustion of gasoline, 47 MJ/kg, and that 0.015% by mass of the hydrogen content in seawater is made of deuterium.

According to the diagram; a) identify the anode of the cell and write the half-reaction that occurs there b) write the overall equation for the reaction that occurs as the cell operates c) calculate the value of the standard cell potential ,e cell. d)write the shorthand notation of the cell above e)indicate the flow of the electrons on the diagram

Use the periodic table to find the molar mass of each element. molar mass h = g/mol molar mass s = g/mol molar mass o = g/mol

Element j is 1s 2s 2p 3s . (i) how many unpaired electrons does j have? (ii) is j a good oxidizing agent or a reducing agent? (iii) state reason for the answer.
