 Let's do another one of these chemical equations This one is a physical change as opposed to a chemical change like the last one we did was So physical change can always also be represented through a chemical equation So what we're saying here is sucrose Okay, so this is like that video where we did the mixtures made the sugar water If you recall that from what was it chapter one? um or lectures at one so sucrose um Is a solid right table sugar and what's happening is we're dissolving it into water to make a solution Sugar water where you don't see the actual particles of sucrose anymore Okay, so again in this case even though it's a physical change We have these essential features of the chemical equation. So again the first thing you want to notice is The reaction arrow So that just tells us some process occurred something happened To the left of the reaction arrow We've got the reactants To the right We've got the product if it's around the arrow. We say they're the reaction conditions If it's water or some other common solvent it is the salt You can't see those particles within the or the solution anymore. So Again go back to that video or dissolve some sugar and water at home And for you understand this physical change. Okay, this is how you write it shorthand
