How does the entropy of a system change when equal volumes of ethanol and water are mixed to form a solution? these are the answer choices: 1. increases 2. decreases 3. stays the same to anyone who can answer this for me.

0.2348 grams of pbcl2 used to form 44.0 ml of solution.

Why is silver chloride is an ionic compound

Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4nh3 (g) + 5o2 (g) → 4no (g) + 6h2o (g) also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition: compound pressure at equilibrium nh3 65.1atm o2 31.3atm no 62.7atm h2o 65.8atm compound pressure at equilibrium nh3 65.3 atm o2 7.79 atm no 12.1 atm h2o 65.8 atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant
