Answer:

Eºcell = -1.78 V

Explanation:

The Eº cell is an intensive property, i.e they do not depend on the quantity of material present and the desired reaction in our problem  is exactly half the reverse of the one given, the Eºcell will then  be the negative of the first then Eºcell is -1.78 V and the redox reaction will be non-spontaneous as opposed to the first.

Please help on 44. /45./ 46./47,
Aleonysh [2.5K]
The only one that I can do without google is 47. Sorry that I can't answer the others. The answer to 47 is this: you know that the western side of the hill has the steepest slope because the ovals showing altitude are way closer together. The closer the circles/ovals are, the steeper the slope is.

Sorry if this doesn't help much, but I answered what I could without cheating.
