when liquid silver nitrate and liquid sodium chloride are combined, solid silver chloride forms along with a new liquid, sodium nitrate. which substance represents the precipitate?
silver nitrate
silver chloride
sodium chloride
sodium nitrate

Option (b) is the correct answer.

Explanation:

A precipitate is defined as the substance formed due to chemical combination of two aqueous solutions. A precipitate is basically an insoluble solid.

For example,

So, here AgCl is the precipitate as it is present in solid state and it is formed because of chemical reaction between silver nitrate and sodium chloride.

Thus, we can conclude that silver chloride is the substance which represents the precipitate.

b) mutualism

hope this : )

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
