The moon is what makes currents so if there was no moon there would be no current in our oceans. The way it makes currents is from the gravitational pull.

<span>It is important to test only one variable when conducting an experiment because that one variable will only have one change. You want to know whether or not that one change is what caused the outcome of the experiment. If you use too many you don't know what really caused the outcome.</span>

1. spontaneous
2. spontaneous
3. Not Spontaneous
4. Not Spontaneous
Palladium and Sn^4+ can be reduced by hydrogen.
Explanation:
If we look at the electrochemical systems represented above, we will notice that in the first two cells, the metal should be reduced looking at the positive electrode potential of the process. This means that hydrogen can reduce the both metals. Electrons flow from the H2(g)/H^+(aq) half cell to the metal/metal ion half cell.
Similarly, when the standard electrode potential is negative, electrons flow from the metal/metal ion electrode to the hydrogen electrode.
Based on the reaction equations, a process is spontaneous if it gives a positive E°cell hence the answers above.
