Not only did it contain water, but a plethora of other compounds and elements including mercury, calcium, magnesium, carbon monoxide and dioxide, ammonia, sodium - and small traces of silver.

土壤中不但含有水分，还有大量其他的成分和物质，例如汞、钙、镁、一氧化碳、二氧化碳、氨和钠——以及少量的银。

We will get 100.1 g of calcium carbonate and then discover that we have 56.1 g of calcium oxide, and 44 g of carbon dioxide.

00。1g的碳酸钙,将得到56。1g的氧化钙，和44g的二氧化碳。
