Compare and contrast between nuclear fission and fusion

Drupady [299]

Both create energy. Both require atoms.

Fission is ripping the atoms apart, fusion is forcing them together. Fission takes less energy because it's easier to rip unstable atoms apart but pushing two atoms that have similar charges together is extremely hard. Fission is currently mainstream on earth, but fusion is known for taking place within stars.

Balance the following redox equations by the ion-electron method:? A) H2O2 + Fe 2+ ---> Fe 3+ + H2O (in the acidic solution)

Vaselesa [24]

We balance the given reactions above by following the rules in balancing redox reactions in acidic or basic solutions. Balance the atoms aside from the O and H atoms. Then we balance the Os and Hs by adding H2O or H+. Finally, we balance the total charge of the reactant and product by adding e-. We do as follows:

<span>A) H2O2 + Fe 2+ ---> Fe 3+ + H2O (in the acidic solution)
</span><span> 2H+ + </span>H2O2 + Fe 2+ ---> Fe 3+ + 2H2O
e- + 2H+ + H2O2 + Fe 2+ ---> Fe 3+ + 2H2O
<span>
C) CN- + MnO4- ---> CNO- +MnO2 (in basic solution)
</span> CN- + MnO4- ---> CNO- +MnO2 + H2O
2H+ + CN- + MnO4- ---> CNO- +MnO2 + H2O
2OH- + 2H+ + CN- + MnO4- ---> CNO- +MnO2 + H2O + 2OH-
   2H2O + CN- + MnO4- ---> CNO- +MnO2 + H2O + 2OH-
   e- + H2O + CN- + MnO4- ---> CNO- +MnO2 + 2OH-
<span>
E) S2O2/3- + I2 ---> I- + S4O2/6- (in acidic solution)
  2</span>S2O2/3- + I2 ---> 2I- + S4O2/6-
4H+ + 2S2O2/3- + I2 ---> 2I- + S4O2/6- + 2H2O
6e- + 4H+ + 2S2O2/3- + I2 ---> 2I- + S4O2/6- + 2H2O

an ant releases a chemical when it dies, and its fellows then carry it away to the compost heap. apparently the communication is

Alenkinab [10]

The conclusion based on the premises is that communication is highly effective.

<h3>What are pheromones?</h3>

Pheromones are chemical substances that are released by animals and which these animals use to communicate with other animals. Some examples of animals that release or produce pheromones are ants and bees.

The pheromones produced by the ants are used to communicate with other ants.

In the given questions, two premises are given about ants:

Premise 1: an ant releases a chemical when it dies, and its fellows then carry it away to the compost heap.

Premise 2: a healthy and painted with the deadly chemical will be dragged to the funeral heap again and again.

The conclusion based on the above premises is that the communication between ants is effective.

In conclusion, ants use pheromones in communication.
