People in the United States in the nineteenth century were haunted by the prospect that unprecedented change in the nation’s economy would bring social chaos. In the years following 1820, after several decades of relative stability, the economy entered a period of sustained and extremely rapid gr...
根据第四段“Soluble ions such as calcium,sodium,potassium,and some magnesium are dissolved and transported.Insoluble ions such as aluminum,iron,and siliconstay where they are and form the thin,fertile skin of soil on which vegetation can grow.”通过这段话可知,可溶性离子如钙、钠、钾、镁,不可溶...
oil,a "drilling rig" is assembled． The most obvious part of a drilling rig is called a "derrick". It is used to lift sections of pipe,which are lowered into the hole made by the drill. As the hole is being drilled,a steel pipe is pushed down to prevent the sides from falling in...
Silver nitrate is a good example of an ionic compound; a chemical formed from the mutual attraction of oppositely charged atomic groups. Silver nitrate is not only ionic, it is also highly soluble in water. Like all ionic compounds, when silver nitrate is dissolved in water, its molecules bre...
