The table shows the range of temperatures of three layers of Earth. Layer Z is found at a depth of 50 to 2,900 kilometers (km) inside Earth. What is Layer X called
and where is it found?

It is the core, and it is found less than 50 km below Earth's surface.

it is the crust, and it is found less than 50 km below Earth's surface.

It is the core, and it is found more than 2,900 km below Earth's surface.

It is the crust, and it is found more than 2.900 km below Earth's surface.

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
