1. How can scientists use fossils in rock layers as evidence that one event happened earlier than another event?​

Chemistry

Komok [63]2 years ago

Answer:

Fossils in rock, in general, provide information about the creatures and plants that lived in the past.

The reason for this is that as those organisms die, they disintegrate and generate silts, which over millions of years go deep into the lithosphere.

As a result, scientists may use the radiocarbon dating technique to determine the age of the fossils. Another method is employed to determine the sort of organism that once existed.

As a result, scientists can infer proof that an event occurred on Earth as long as a million years ago through the application of these approaches.

Is this equation completely balanced? 2C8H8 + 25O2 8CO2 + 18H2O No, because the number of carbon, hydrogen & oxygen atoms on
Sergio039 [100]
<span>So to make it clear let's break the equation down species by species and assess the number of each species on bothe sides of the equation:
                   2C</span>₈H₈  +  25O₂   →   8CO₂ +  18H₂<span>O
LHS:  C - 16                                           RHS:  C - 8
          H - 16                                                     H - 36
          O - 50                                                    O - 34

Thus based on that it is evident that the equation is not quite balanced.  This therefore means a "</span><span>No, because the number of carbon, hydrogen & oxygen atoms on both sides of the equation are not equal."

</span>The actual balance equation would be C₈H₈  +  10O₂   →   8CO₂ +  4H₂O

Why has nuclear fusion been difficult to develop?
Alex73 [517]

Answer:

C. It is hard to recreate the extremely high temperatures and pressures found inside stars.

Explanation:

Nuclear fusion occurs when atomic nuclei are forcefully combined to create a new atomic nuclei or subatomic particles. In nature, this process takes place in our Sun and other stars. Within stars, extremely high temperatures and pressures are achieved and cause nuclear fusion to occur. Humans have not yet been successful in recreating the environment necessary to mimic this process.
