The bubbles that are being formed in this reaction are filled with carbon dioxide These bubbles are denser than air so they float to the top which actually is part of the reason the chemical reaction happens. Fizz is a great indicator that a chemical reaction happened because you simply can see with your own that there is fizz to help verify a chemical reaction happened.

The Alka Seltzer plus water experiment makes sense because the tablet contains both citric acid and sodium bicarbonate. When they hit the water, they react. As said before, fizz is a great indicator that a chemical reaction happened because you simply can see with your own that there is fizz to help verify a chemical reaction happened.

The milk acidifies because of bacterial fermentation giving it a sort of sour taste, hence the name souring milk. It also doesn't smell too good because it's been sitting out for a while. Aroma is a definite indication of a chemical reaction (and definitely not as fun to be around). There is also a solid produced.

For example, if you have a dog and they eat a bowl of food, although they might gain a little weight, they are still a dog.]]> 2018-03-11 18:51:37 UTC https://padlet.com/robertgetty2022/rohlorb2ryrv/wish/240611588 Wood Burning robertgetty2022 https://padlet.com/robertgetty2022/rohlorb2ryrv/wish/240614064 6C10H15O7 + Heat --> C50H10O + 10CH20

When wood burns for a long time, eventually all you are going to have left is just ashes, so that is why this is a chemical reaction. Since the fire is being put with another substance in an oxygen controlled environment. This is also a color change and temperature change because before the reaction occurred, the ashes were black instead of brown. Also, the temperature decreased. This illustrates substantial evidence to point to prove a chemical reaction occurred.]]> 2018-03-11 19:07:57 UTC https://padlet.com/robertgetty2022/rohlorb2ryrv/wish/240614064 Baking a Cake robertgetty2022 https://padlet.com/robertgetty2022/rohlorb2ryrv/wish/240618026 Chemical Equation: Unknown
Baking a cake changes from a chunky liquid, to a moist solid (precipitate). It also can have a color change and a temperature change after coming out of the oven, than before it. Since it looks different than it did before it went in the oven, it's a chemical reaction.]]> 2018-03-11 19:35:41 UTC https://padlet.com/robertgetty2022/rohlorb2ryrv/wish/240618026 Bibliography robertgetty2022 https://padlet.com/robertgetty2022/rohlorb2ryrv/wish/240618363 “Alka Seltzer.” Youtube, www.youtube.com/watch?time_continue=116&v=s9biuKhnSdU.
