C. At some point, the land masses were connected to each other.

Explanation:

The fossils now exists far away from each other because at some point, the land masses were once connected to each other. Now, the land masses have drifted apart due to plate tectonics.

Alfred Wegener a scientist in 1912 first formulated the theory of continental drift. The theory suggests that present day land masses have moved to their present positions.

A more refined theory of plate tectonics is now in play today and it provides a better understanding to why we can find similar features across different continents.
The similar fossils must have formed together when the land masses were once joined together.
Noe that the land masses are separated, the fossils species are not separated.

When 15.3 g of sodium nitrate, NaNO3,was dissolved in water in a calorimeter, the temperature fell from 25.00oC to 21.56oC. If t

satela [25.4K]

Answer:

20.468 kilo Joules is the enthalpy change when one mole of sodium nitrate dissolves.

Explanation:

Heat lost by solution ad calorimeter = Q

Heat capacity of solution ad calorimeter = C = 1071 J/°C

Change in temperature = ΔT = 21.56°C - 25.00°C = -3.44°C

$Q=C\times Delta T$
