Answer: Force disadvantage and distance advantage
Explanation: When mechanical advantage is less than one the force of the strength decreases because input force is greater than output force.
The distance increases ie the object is moving over a long distance.
Example when fishing with a long fishing rod the force applied to move the fish from the water is greater than the weight of the fish itself. The advantage of using the long fishing pole is that the distance over which the fish travels is greatly increased.
Hope this helps. It took me about half an hour before I could get this answer from my various searches. The idea might not be clear but this was what I was able to understand.
Answer:
Reduced species and oxidizing agent: sulfur in the form of sulfate.
Oxidized species and reducing agent: chromium in the form of chromous hydroxide.
Explanation:
Hello!
In this case, for the reaction:
We can see that the oxidation states of sulfur and chromium change from +6 to +4 and +3 to +6 respectively; in such a way, since the oxidized species is the same reducing agent because it undergoes an increase in the oxidation state, we infer that chromium is it as it goes from +3 to +6.
Moreover, since the reduced species is the same oxidizing agent because it undergoes a decrease in the oxidation state, we infer that sulfur is it as it goes from +6 to +4.
