Please help. I need this ASAP. It's for a test. I'll give Brainliest to whoever answers correctly.
Drag each tile to the correct location. Classify the reactions as endothermic or exothermic.
Possible Choices:
1.) The reaction between ammonium nitrate and water absorbs heat from the surrounding environment.
2.) Three drops of concentrated sulfuric acid added to 100 milliliters of water in a beaker makes beaker hotter.
3.) Ammonium chloride dissolved in a beaker of water makes the beaker cold.
4.) Uranium atoms are split to produce nuclear energy.
5.) Water separates into hydrogen and oxygen when an electric current runs through it.
6.) Methane and oxygen are combined to produce methanol and heat.

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.
