1. When water is added to agricultural lime (CaCO3), calcium hydroxide, a base, is produced in the following reaction: CaO(s) + H2O(l) → Ca(OH)2(s)
The solid calcium hydroxide dissolves in water and the solution become alkaline.
Ca(OH)2(s) + (aq) → Ca(OH)2(aq)
Based on the information, determine the neutralization reaction involved when agricultural lime is added to a lake with a high volume of nitric acid. Identify the net ionic reactions involved in the neutralization reaction involving lime. What salt was formed during the neutralization reaction? Describe the salt formed.

What is the volume occupied by 10.0 dm3 of gas at standard pressure after it has been compressedat constant temputure to 500.0 kpa?

Two nitro no2 groups are chemically bonded to a patch of surface. they can't move to another location on the surface, but they can rotate (see sketch at right). it turns out that the amount of rotational kinetic energy each no2 group can have is required to be a multiple of ε, where =ε×1.010−24 j. in other words, each no2 group could have ε of rotational kinetic energy, or 2ε, or 3ε, and so forth — but it cannot have just any old amount of rotational kinetic energy. suppose the total rotational kinetic energy in this system is initially known to be 32ε. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ε. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.
