3. Use the limiting reagent to determine how many grams of Cu(OH)2 should precipitate out in the reaction. Show your work 4. If only 174.6 g of Cu(OH)2 precipitate were actually collected from the reaction, what would the percent yield be? Show your work

I'LL GIVE YOU BRAINLIEST JUST PLEASE SHOW YOUR WORK I'D GREATLY APPRECIATE IT!!

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

the answer would be a
