Identify the precipitation reactions. drag the appropriate items to their respective bins.
lana66690 [7]
I can't fully answer this question because it is incomplete. In order for me to help you, I could just define what a precipitation reaction is and give a concrete example.

A precipitation reaction consists of two aqueous solutions that when reacted together, forms an insoluble salt. For example, 

AgNO₃ (aq) + HCl (aq) --> AgCl (s) + HNO₃ (aq)

In this case, the precipitate is AgCl, Silver Chloride, which appears as a white solid.

nasty-shy [4]

The <u>Empirical formula</u> gives the smallest whole number ratio of moles of each element in a compound. therefore, multiple compounds may have it in common.

<h3>What is Empirical formula?</h3>

The most straightforward whole number ratio of atoms in a compound is its empirical formula. The empirical formula for sulfur monoxide, or SO, and disulfur dioxide, or S2O2, are both straightforward illustrations of this idea.

<h3>What is multiple compounds?</h3>

According to the law of multiple proportions, if two elements combine to form more than one compound, the ratio of the second element's mass to the fixed mass of the first element will always be a ratio of tiny whole numbers.

<h3>What is empirical formula used for?</h3>

Typically, the empirical formula is used to simply display the components of a molecule. When one needs to quickly identify the elements they are working with, this is helpful. When you want to know how many atoms of each element are present in the molecule, the molecular formula is most helpful.
