Since lennie kept accidentally killing his pet mice because he pet them too hard, his aunt Clara him this item instead , but lennie didn’t like it. What was the item that ain’t Clara gave lennie when he lived at her farm ?

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
