In your own words, explain how/why precipitates form. Also explain what spectator ions are.
Andrej [43]

A precipitate is a product of a reaction that is insoluble in the reaction medium (usually water).

Why?

One of the signs that a reaction happened is that a precipitate forms. Let's take the reaction between Silver Nitrate (AgNO₃) and Sodium Chloride (NaCl) as an example:

AgNO₃(aq) + NaCl(aq) → AgCl(s)↓ + NaNO₃(aq)

In this reaction, Silver Chloride (AgCl) is an insoluble product of the reaction, and precipitates out of the reaction medium

If we write down the ionic equation, we find out the following:

Ag⁺ + NO₃⁻ + Na⁺ + Cl⁻ → AgCl(s) + Na⁺ + NO₃⁻

The ions that appear at both sides of the arrow are called spectator ions, since they are not directly involved in the process of the reaction, making the net ionic equation to be:

Ag⁺ + NO₃⁻ → AgCl(s)

Have a nice day!

Which one is equivalent to 28% by mass? 0/1 point O 28 g solute perg of solvent 28 g solute per g of solution 28 g solute per 10
astra-53 [7]

Answer:

28 g solute per 100 g of solution

Explanation:

28% mass means that in all your solution you have 28% of your solute, you could use grames/grames, ml/ml or whatever you want to. So if you are working with a 100 grams solution, 28 grams of that solution must be solute if you want a 28% mass. So, the correct answer is 28 g solute per 100 g of solution.
