Hey everyone, I was looking for some information about physical reactions. My friend has a project and needs help! If you know anything please reply

Chemical reactions

Hi I am looking to do a science experiment. Does anyone have any suggestions on what I should do?

Law of Conservation of Mass

Does anyone know what the Law of Conservation of Mass is?

Chemical and Physical changes

abbytstewart10 — 2024-03-22 21:31:59 UTC

Does anyone know what the Chemical changes and Physical changes are? I can never remember what the difference is.

Open and Closed systems

I was just reading an article and saw open and closed systems, I have no idea what either of them mean. Does anyone know what they mean and what the differences are?

Reactants and Products

What’s the difference? I was just with my friends and she was solving chemical equations using products and reactants and trying to make them equal. Does anyone know what these terms mean?

Does anyone know the difference? I can never tell what the differences are, they all seem the same to me.

Coke+mentos

I just finished my experiment and chose Coke and Mentos. The reaction was very surprising to me! Some of the safety precautions I used were making sure I had a bowl around so that it did not explode and go everywhere. The only ingredients that I used were Diet Coke and Mentos. The steps I took were, first I bought a cup of diet coke and mentos, then I put the items in a bowl and then mixed them and watched the reaction.

Does anyone what some physical reactions are?

H₂O + CO₂ ——> H₂CO₃

Open or Closed?

abbytstewart10 — 2024-03-27 16:07:53 UTC

The system is open because the bubbles fizz and rise up in the cup.

Relations

This relates to the experiment because even though a chemical reaction occured none of the molecules or atoms were losed and no atoms or molecules were created.
