Thallium consists of 29.5%TI-203 and 70.5%TI-205. What is the relative atomic mass of thallium?
Kazeer [188]
Since you are referring to the TI-203 and TI-205, you need to know the actual masses of these two isotopes. TI-203 has 202.9723 amu  and TI-205 has 204.9744 amu. Since you are concluding that this Thallium have 29.5% (Ti-203) and 70.5% (Ti-205), you need to multiply the percentage to the actual masses of the isotopes. With that, you should be able to get 204.3833 amu

Explain the theory of plate tectonics and how they have changed Earth’s surface over time. Include the role of plate tectonics i
Cerrena [4.2K]

Answer:

The theory of plate tectonics describes the movement of the plates across the Earth's lithosphere (the crust and upper mantle) through immense periods of time. Earth's litoshphere is composed of 7 (or 8, depending on how they are defined) major plates and many more minor plates.

The movement is attributed to different phenomena stemming from Earth's rotation, gravity, and mantle dynamics. All of these forces play a role in influencing the size, shape, and positioning of the different landmasses that currently shape our continents and islands.

Explanation:

In a nutshell, land originated from magma in the Earth's core escaping through the cracks and making its way to the ocean. The water cooled down the magma and this process created all of the land both above and below the sea. The landforms that we see all around the Earth today were formed thanks to collisions and separations of the plates thoughout billions of years.
