The reaction na 3po 4( aq) 3 agno3( aq) → ag 3po 4( s) 3 nano 3( aq) is best classified as a(n):_____.

Ugo [173]

The reaction $Na_{3} PO_{4} ( aq) +3AgNO_{3} (aq)$ → $Ag_{3} PO_{4} ( aq) +3NaNO_{3} (aq)$ is best classified as double displacement reaction.

Those reaction in which two compounds react by exchanges of ions to form two new compounds is called double displacement reaction. The easiest way to identify double displacement reactions is to check to see whether the cations exchanged anions with each other or not . Always balanced chemical equation is used to determine.

There are three types of double displacement reaction which is given as,

Precipitation
Neutralization
Gas formation

The real world example of double displacement reaction is combining vinegar and baking soda to create homemade volcano.

A graduated cylinder was filled to 20.3 mL with water. A solid object weighing 73.05 g was immersed in the water, raising the me

victus00 [196]

The density of the solid object will be 2.63 g/mL

<h3>What is density?</h3>

Density of objects = mass/volume.

Recall that an object will always displace its own volume when placed in a liquid.

Volume of the solid object = Cylinder reading after immersing the object in the water - cylinder reading before immersing the object in the water.

= 48.1 - 20.4

= 27.8 mL

Mass of the solid object = 73.05 g

Density of the object = 73.05/27.8

= 2.63 g/mL
