Explain the advantages of using slaked lime instead of powdered limestone for neutralising acidic soil?
Slaked lime is much more alkaline and effective at reducing acidity quickly - it is Ca(OH)2 whereas powdered limestone is CaCO3 and not as alkaline/basic. CO2 is also given off when the limestone reacts with the acid. Water is given of when slaked lime reacts. Mathematically it takes 100 g of limestone to 73g of HCl (as an example) where it would take only 74g of slaked lime per 73g HCl.
Explain how limestone purifies the iron?
When limestone reacts with iron, it removes impurities and forms slag, which is less dense than molten iron and therefore floats over it, allowing it to be tapped off seperatly. It (the slag) is rather useless, but can be used in concrete.

Theory stating that the sun contains a small amount of platinum using what you know about spectroscopy explain how i might prove or disprove this theory?
We cannot tell you how to explain a theory with what we know. You must explain it with what you know.

the rain water is soaked up and held underground in the porous limestone floating on top of salt water.
How do space stations reuse water?
Well it is to do with the same way as we often do on Earth, but I don't know how appropriate it would be to explain it in detail on a website like this.
In your own words explain how a stalactite forms?
Most stalactites are limestone. Water, often rainwater, seeps through material which causes it to absorb carbon dioxide, as it seeps further it dissolves limestone. Then when it reaches the ceiling of a cave it slowly begins to forms droplets. As these dry they deposit the limestone on the ceiling. This happens again and again, one drop at a time, and very slowly over years this deposit grows forming a stalactite.

A stone roof is supported by collumns made up of limestone why might this be unsafe after a fire in a building explain the chemical process involved in the weakening of the structure?
Limestone is CaCO3. Let us decompose it:CaCO3 ---> CaO + CO2Heating the limestone will cause the above reaction to take place and replace the relatively firm structure of the limestone rock with a more powdery structure of the CaO. Another example might be this:Mg + (1/2)O2 ---> MgOThe relatively hard structure of the magnesium metal is replaced by a powdery MgO and the MgO structure falls apart into a heap of MgO dust.Source(s):ChemTeam
