Which solution will form a precipitate when mixed with a solution of aqueous na2co3?

When mixed with a solution of aqueous sodium carbonate, a solution containing copper (II) ions will form a precipitate.

Explanation:

A precipitation reaction is a reaction in which one of the products is insoluble in the solvent of the reaction (this is usually water).

These reactions are one of the types of double-displacement reactions in which the cations and anions of the reactants are inter-changed.

When mixed with a solution of aqueous sodium carbonate, a solution containing copper (II) ions will form a precipitate which is insoluble in water.

The copper (II) ions will form together with the carbonate, a precipitate. Which will be insoluble. An example is CuSO4.

Na2CO3 + CuSO4 →   2Na+ + CO32- +  Cu+  +  SO42- →2Na+ + SO42- + CUCO3

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
