CaO + H2O -> Ca(OH)2
Here, CaO is Quick Lime, and Ca(OH)2 is slaked lime.
Technically, you get slaked lime after this reaction. Also, it's exothermic, so you've got a lot of heat coming out, and the water could in fact start boiling, that much heat.
Cheers :)
an exothermic reaction occurs - a large amount of heat is released. an exothermic reaction occurs - a large amount of heat is released.
depending on the amount, if lots of water is added, then there will be more of a temperature rise.
When quicklime (CaO) is placed in water calcium hydroxide is formed -
Ca(OH)2.
slacked lime is formed
Water is added to quicklime the make slaked lime. Calcium hydroxide reacts with water to form calcium hydroxide. CaO + H2O --> Ca(OH)2
A vigorous reaction between water(steam) and quicklime produces calcium hydroxide as a residue.
When water changes to water vapor, it has changed its state from liquid to vapor and no chemical change has taken place. It's only a physical change.
The sun.
the state of matter that changes shape when placed in a different container is water
Quicklime (CaO) is alkaline in water.
slaked lime is made by adding water to quicklime.
I would like to know what important substances that can be made from Quicklime?
Quicklime reacts with water, limestone doesn't. That's probably the fastest way.
water
Lime (quicklime) is made from limestone- but it is not the same thing. Agricultural lime is powdered limestone. Quicklime is limestone (calcium carbonate) that has been roasted and changed to Calcium Oxide. Slaked quicklime is quicklime that has had water added- Calcium hydroxide. Quicklime is used for odor control.

what changes take place when water is heated or cooled
Formula: Ca(OH)2
Water is added to quicklime the make slaked lime. Calcium hydroxide reacts with water to form calcium hydroxide. CaO + H2O --> Ca(OH)2
Firstly, the limestone is heated to produce quicklime (calcium oxide - CaO) and carbon dioxide (CO2). The a small amount of water (H2O) is added to the quicklime, to produce slaked lime (calcium hydroxide - Ca(OH)2). In conclusion: limestone quicklime + carbon dioxide quicklime + water → slaked lime I really hope that helped! :)
