Hello my wonderful students!!! Listen closely...are you listening??? This is your science teacher Ms. Yates. I know, I know. I just saw you a few hours ago. Remember the awesome reminders, updates, and fantasticness that I promised you?? It is here. Yep!! Right here. Remember to check it out daily. The rewards will be worth your time. Assignments that you forgot about or were absent for? Here!! Notes you may have missed?? Here too!!! Announcements?? Yep!! And, fantastic reminders of all the cool stuff we did today...All here and more!! See you tomorrow. Or Monday, if you are so awesome that you are reading this over the weekend.

Chemical reaction investigation
Where did the bubbles come from in cups 1 & 3? What was the solid that formed in cup 1?
Pragathi 1. The bubbles in cups one and three came from the mixture of the substances and water, which caused the result to emit gas(CO2). 2. The solid that formed in cup one was a precipitate. This lab was fun! Science ROCKS!!!!
A chemical reaction and chemical reaction formed the bubbles in cups 1 and 3. I believe that precipitate was the solid at the bottom of the cup. In this case, it is the calcium chloride. Sourav
Amelia The chemical reaction, in which gave off gas, which formed bubbles in cups 1 and 3. Cup 1 was a mixture that had precipitate at the bottom of the cup. The undissolved calcium chloride remained at the bottom of the cup.
QUINN, the bubbles came from the reaction releasing the co2. I think the solid was salt or something like that.

ReplyDeleteThe bubbles came up in cups 1 and 3 as a result of a chemical reaction which released carbon dioxide.

ReplyDeleteThe solid that formed in cup 1 is called precipitate.
(Sorry, I forgot to add it to my earlier one)

ReplyDeleteThe bubbles came from the chemical reaction and it released carbon dioxide. the solid that formed in the cup was precipitate. I like this lab!

ReplyDeleteThe bubbles came from the baking soda in the solution. The solid was bubbles????

ReplyDeleteThe chemical reaction brought the bubbles in cup 1 and 3. The calcium chloride did not dissolve completely.

co2 formed in the cups. the solid is precipitate.
ReplyDeleteThe bubbles were from the acid. The calcium chloride hardened on the bottom of the cup.
