BRAINLEST + 15 POINTS EACH The models below represent nuclear reactions. The atoms on the left of the equal sign are present before the reaction, and the atoms on the right of the equal sign are produced after the reaction. Model 1: Atom 1 + Atom 2 = Atom 3 + energy Model 2: Atom 4 = Atom 5 + Atom 6 + energy Which of these statements is most likely correct about the two models? Both models show reactions which produce energy in the sun. Both models show reactions which use up energy in the sun. Model 1 shows reactions in the nuclear power plants and Model 2 shows reactions in the sun. Model 1 shows reactions in the sun and Model 2 shows reactions in a nuclear power plant.

There are two kind of nuclear ractions: fusion and fission reactions.

Both release a huge amount of energy in different ways.

Fusion reactions are nuclear reations in which two smaller (lighter) atoms combine into a larger (heavier) atom, with the respective release of energy.

That is what model 1 shows:

Model 1: Atom 1 + Atom 2 = Atom 3 + energy

That is the process that happens and is responsible for the huge amount of heat produced in and released by the Sun.

In the Sun two atoms of hydrogen fuse into a larger atom of helium.

That is represented by the nuclear reaction:

Third choice: Model 1 shows reactions in the sun and Model 2 shows reactions in the nuclear power plants.

In the Sun two atoms of hydrogen fuse into a larger atom of helium.

That is represented by the nuclear reaction:

→  + some other particles

Since fusion reactions need extremely high temperatures and pressure to start and keep going, the technology to use them economically is still in development.

Fission reactions involve the split of the atom into smaller (lighter) atoms, releasing a huge amount of energy.

That is depicted by the model 2:

Model 2: Atom 4 = Atom 5 + Atom 6 + energy

As you see one atom is being splited in two atoms with release of energy.

And indeed, that is the technology used by the nuclear power plants.

An example is the fission of uranium-235

electronic measurement tools display data on a screen after waiting for several minutes.

while some business owners prefer manual record keeping systems, most businesses use an electronic record keeping system - making it easier to capture information, generate reports and meet tax and legal reporting requirements.
