Question 1196740
----------------------------------------------------------------------------------------------------------------------------------------------------------------
Answer the given problem, by determining the amount of products or reactant.

1.Limestone (CaCo3) is decomposed by heating to quicklime (CaO) and carbon dioxide. Calculate how many grams of quicklime can be produced from 1.0 kg of limestone.

2.Nitrous oxide (N20) is also called "laughing gas". it can be prepared by the thermal decomposition of ammonium nitrate (NH4NO3). The other product is H20. a.Write a balanced equation for this reaction. B. How many grams of N20 are formed if 0.46 mole of NH4N03 is used in the reaction.

Help for question #1 only:


CaCO_3,   100.0869 grams/mole
CaO,   56.0774 grams/mole


CaCO_3 ----- > CaO  +  CO_2


One-to-one mole relationship between the limestone and the quicklime.


{{{1000*grams*limestone*(1/100.0869)((moles*limestone)/(grams*limestone))*1((mole*quicklime)/(mole*limestone))*56.0774((grams*quicklime)/(moles*quicklime))}}}


{{{((1000*56.0774)/100.0869)*GRAMS*quicklime}}}
Just compute this!


If you understand question #1, then you know what to do for question #2.
