Answer:
How fast and efficient the energy is released.
Explanation:
Before burning the marshmallow energy is stored in it in the form of chemical bond energy or chemical potential energy. So upon burning this energy is released. So there will be a difference in energy release from a burned marshmallow and the one we eat straight from package.
C) During the radioactive decay, alpha particles are released. These positive particles are attracted to the negative plate in the electric field
Explanation:
In nuclear reactions, it should be known that the mass and atomic numbers are usually conserved.
²³⁸₉₂U → ²³⁴₉₀Th + ⁿₐX
This implies that:
238 = 234 + n
92 = 90 + a
When this is true, then the nuclear reaction is balanced. Both atomic and mass numbers can be said to be conserved.
Solving for n and a
n = 4
a = 2
Therefore
²³⁸₉₂U → ²³⁴₉₀Th + ⁴₂He
The particle resulting from the decay is an alpha particle. Alpha particles resembles a Helium atom.
Alpha particles are positively charged and they are attracted to the negative plate in the electric field.

Answer:
the importance that the experimental and predicted values are equal is to know the validity of the models and approximations used.
Explanation:
The different models and laws of physics create perditions on the results that must be obtained under certain conditions.
To know if these models and laws are true, experiments are designed that give experimental results, which can be compared with those predicted if the models are true and accept as correct and if they are different, the moldings are reviewed and modified to be more similar to reality.
Therefore, the importance that the experimental and predicted values are equal is to know the validity of the models and approximations used.
