By comparing fossils of different primate species, scientists can study
how different species have diversified over time.<span> Almost all sediment is either laid down horizontally in
bodies of water like the oceans, or on land on the margins of streams and
rivers. Each time a new layer of sediment is deposited it is laid down
horizontally on top of an older layer. With this events, Geologists can
established a set of principles that can be applied to sediments and to
determine how these features evolved through time.</span>
Fluorine in its standard state is F2.
Sulfur Dioxide is erupted from volcanoes and is an important part to acid rain.
Answer:
2.9g/cm^3
Explanation:
We're given that the mass of the system before the rock was added was
120g
. The mass after the rock was added was 250g, so the rock's mass is 130g.
The initial volume of water in the graduated cylinder was
30
mL
, and the volume after the rock was added read 75mL
, so the rock's volume is 45mL
Density = Mass over Volume.
AKA. 130g/45mL
2.9g/cm^3 (rounded)
