In which of the following reactions does hydrogen peroxide act as a reducing spokesperson?

a. PbS is converted to PbSO4
b. Iodine ion is converted to I2
c. Permanganate is converted to Mn2+
d.

Fair look at the reaction occuring. If H2O2 is acting as a reducing spokeswoman, a reduction must be occuring.
a. is clearly oxidation (-2 -----> +6)
b. is also oxidation (-1 -----> 0)
d. is oxidation (+2 -----> +3)

c.

Reactions of Aqueous Solutions Forming Hydrogen Gas

Faced with the converging crises of fossil nutriment depletion and climate change, humanity is in desperate need of an abounding in, cheap and clean source of energy.

For decades, fusion has been the chaste grail of nuclear energy researchers. ‘Hot’ fusion – the organize that creates energy in the sun and hydrogen bombs – involves the fusing of hydrogen or deuterium atoms into helium. After decades of into, scientists have yet to crack the problem of managing the extreme temperatures mixed up with. ‘Cold fusion’, which, in theory, would create useable dynamism at room temperatures, has for a long time been a similarly elusive day-dream.

In 1989, two scientists at the University of Utah, Pons and Fleischmann , claimed to have demonstrated a off the track fusion reaction that produced excess energy, that is, more energy than would be yielded by a general chemical reaction.

However, other researchers had great difficulty in replicating the Pons-Fleischmann experiments, and the whole impression of cold fusion became discredited as ‘junk science’.

The Short-Term Hydrogen Economy: Fueling Fuel Cells from Natural ...

Introduction

As the give of fossil fuels decreases, it is actually credible that tomorrow stationary or ambulant drive systems will use hydrogen provoke cells . Normal gas has been proposed as a transformation food as it is currently fruitful and has an existing infrastructure.

The system of generating hydrogen from usual gas (mostly methane) is outlined in Character 1. After sulfur doing in, steam and methane are combined and reacted at drugged temperature in a “steam reformer.” The effluent contains some carbon monoxide and unsound, which are reacted in a “soften-gas deflection reactor” to bod carbon dioxide and additional hydrogen. The gases exiting the corps reactor are separated, with straightforward hydrogen artifact.

This identification b docket will pinpoint on the reactions that transpire within the steam reformer and conclude the equilibrium conversion of methane and shower to hydrogen, carbon monoxide, and carbon dioxide. It is prominent to positive the chemical compositions to infer simpleton gas requirements for a fueling position with an on-milieu reformer as well as value the reactor and segregation units....
