2. When paleontologists study fossils, which is true of the fossil record that they find? (12.5 Points)
O A. The fossil record shows that organisms have changed very little over time.
B. The fossil record is inconsistent with the scientific theory of evolution.
O C. The fossil record is very limited and offers little knowledge about the history of life.
O D. The fossil record shows how different groups of organisms have changed over time. Option 1

Explanation:

d

The answer would be D the last one cause it shows how the animal has changed over time.

Explanation:

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
