So today we'll be showing you an example of a chemical change. I was thinking of dissolving salt in water
Wait, don't you mean that it's an example of a physical change
Linda, we talked about this, I'm the scientist heare.
you sure about that, Falisha ? I'm pretty sure I'm right and your wrong
ahhem (clearnig through), well it's physical because when you add sugar to water it's a physical change so it's probable the same as salt.
since your the expert here tell me then ,why is it a physical change?
you bum,it's totally a chemical change
When you dissolve salt in water, the sodium chloride dissociates in Na+ ions and Cl- ions, which may be written as a chemical change.Therefore, dissolving salt in water is an exampl. The reactant (sodium chloride or NaCl) is different from the products (sodium cation and chlorine anion). Thus, any ionic compound that is soluble in water would experience a chemical change. In contrast, dissolving a covalent compound like sugar does not result in a chemical reaction. When sugar is dissolved, the molecules disperse throughout the water, but they don't change their chemical identity.
okay then, prove it
do you want me to continue because i can
why would you need a new job, you know everyone makes mistakes, even me, like what,? i make mistakes? ok sorry got distractide. like I was saying just because you made a mistake you don't need to give up. either way I need a partner like you, so your not going anywere.
okay, okay, I won't leave , this is going to be a long year of arguing.
no, no, it's okay, i really did think it was a physical change. well time for a new job
you think we can start class now?
oh, I thought class was over, I had totally forgotten we had a class to tech
