The chemistry of limestone: curriculum references

English National Curriculum
4.2.4i that the fossil record is evidence for evolution
4.3.2r how the sequence of, and evidence for, rock formation and deformation is obtained firm the rock record
4.3.3k about different types of chemical reaction, including thermal decomposition and how these are used to make new materials
CCEA (Northern Ireland)
3.4.1 demonstrate a knowledge that materials can be decomposed by heat including the decomposition of limestone
3CRc learn that useful products can be manufactured form various raw materials, for example, the production of lime from limestone
3CRd investigate different types of chemical reaction, including: .. thermal decomposition, for example, the effect of heat on calcium carbonate ...
3CRg Find out that some chemical reactions are exothermic for example, that an increase in temperature occurs when water is added to calcium oxide.

4.3.2.15 that a variety of useful substances can be made from rocks and minerals
OCR A  
3.1.14 state the effect of heat on limestone to produce quicklime (calcium oxide) and recognise this as an example of thermal decomposition
3.1.15 describe and explain the changes that take place when water is added to quicklime
OCR C
Sc3.2.3.4 know that a variety of useful substances can be made form rocks and minerals
Sc3.3.6.1 know that some substances decompose on heating (limited to action of heat on carbonates)
AQA
3462 ref 11.5 When limestone is heated in a kiln it breaks down into quicklime (calcium oxide) and carbon dioxide. This type of reaction is called thermal decomposition (other carbonates behave in a similar way). Quicklime reacts with water to produce slaked lime (calcium hydroxide) which is used to reduce the acidity of soil.
3468 ref 15.1 When limestone is heated in a kiln it breaks down into quicklime (calcium oxide) and carbon dioxide. This type of reaction is called thermal decomposition (other carbonates behave in a similar way). Quicklime reacts with water to produce slaked lime (calcium hydroxide) which is used to reduce the acidity of soil.
