chemistry
When .03 mol Na is added to 100g of water, the temp. of the resulting solution rises from 25C to 37.9C. If the specific heat of the solution is 4.18 J/(g C), calculate delta H for the reaction, 2Na(s) + 2H2O(l) --> 2NaOH(aq) + H2(g)

Carbon
#1 where and in what form does carbon enter long term stores? It enters long-term stores in the form of Carbon dioxide, and is found in intermediate and deep ocean waters. On land, it is found in coal-deposits and in oil and gas deposits. #2 where and in what form does carbon ...
