The rock layer which marks the end of the dinosaurs is: C. KT Boundary layer.
A rock can be defined as a solid material containing minerals, which are naturally formed through the following processes:
Basically, a rock comprises of various layers which marks the age of both living and nonliving organisms, these includes:
I. Burgess Shale layer.
II. Mesozoic Layer.
III. KT Boundary layer.
Dinosaurs refers to a taxa of carnivorous or herbivorous archosaurian reptiles that are often very large and belongs to the Mesozoic era.
Basically, the Mesozoic Layer is a rock layer which marks the period when dinosaurs were still roaming the earth some million years ago.
However, dinosaurs went into extinction at the KT Boundary layer and as such it is a rock layer which marks the end of the dinosaurs.

Answer:
Sr 2+(aq) + SO42-(aq) → SrSO4(s)
Explanation:
<u>Step 1</u>: Write a properly balanced equation with states:
K2SO4(aq) + Srl2(aq) → 2KI(aq) + SrSO4(s)
<u>Step 2</u>: write the full ionic equation with states. Remember to keep molecules intact. Only states (aq) will dissociate, (s) will not dissociate
. This means SrSO4 won't dissociate.
2K+(aq) + SO42-(aq) + Sr 2+(aq) + 2I-(aq) → 2K+(aq) + 2I-(aq) + SrSO4(s)
<u>Step 3</u>: Balanced net ionic equation
Sr 2+(aq) + SO42-(aq) → SrSO4(s)
Answer:
weight = mg
= 2 X 9.8 (g = 9.8m/s^2)
= 19.6 N is the correct answer
potassium sulfate or A because K2 is potassium and SO4 is sulfate
The answer is C. SiO2 :)))
