please help me answer the first to answer correct and fast will get brainliest

Answer 1

Question :

The equation represents a reaction between two solutions.

$\rm{AgNO_3(aq)+HCl(aq)\longrightarrow{}HNO_3(aq)+AgCl(s)}$

What is the residue when the reaction mixture is filtered?

A. AgCl

B. AgNO₃

C. HCl

D. HNO₃

$\hrulefill$

Answer :

• The residue is = AgCl (silver chloride).

• The reaction of silver nitrate and hydrochloric acid is a perception reaction. This means that a precipitate (an insoluble solid mass) is formed in the reaction and it cannot be filtered. Hence, it will be left out as a residue when the reaction mixture is filtered.

• In our reaction, silver chloride is the precipitate formed and it will be left out as the residue.

• Therefore, the answer is option A.

$\hrulefill$

Additional Information:

Precipitation reaction:-

• When two clear solutions of ionic compounds are mixed, an insoluble substance is formed. This insoluble substance is known as precipitate. Simply, any reaction that produces such a percipitate can be called a precipitation reaction.

Answer 2

The residue is = AgCl (silver chloride).

Therefore, the answer is option A.
