Lime can be used to start a fire if it is exposed to water. For example, leave a bag of lime outside in the open air. When it rains, the water coming in contact with the lime is able to cause a reaction that starts a fire.If you want the actual chemical equation:CaO + H2O -> Ca(OH)2 OR Calcium Oxide + Water = Calcium Hydroxide
no, it will weigh heavier because it will dry into cement when mixed with water and the weight of water will add to the weight of the concrete.
This depends on the size of the pool. Generally, when you buy chlorine, it should say on the bag or box how much to use for what size pool.

It weights 1.5
Most bags will make a 1/3 of a cubic foot of concrete.

An 80-pound bag of premixed cement = .667 cubic feet, or 2/3 of a cubic foot, of concrete. A 60-pound bag of premixed cement = .5 cubic feet, or 1/2 of a cubic foot, of concrete.

yes they need to be set in concrete. depending on your fence, one bag of concrete per post should be enough.
Every 80lb concrete bag should be mixed with 4 quarts or 3.7 liters of water. This mixture will allow you to place aproximately .60cu/ft of concrete. There are 27 cu/ft in a cu/yd. The number then becomes .0222 yards per 80lb bag. Therefore 45 bags of 80lb (4000 psi) concrete ready mix will be enough for 1 yard of concrete.
This all depends on the mix you want. I assume you mean cement when you mention the 80lb bag of concrete. I have pushed concrete in my day... Bag cement mix is the same as concrete. Don't be funny. How many 80 pound bags will make 1 yard of concrete? I want a definitive answer this time.
NO!
