Yes. It is only through creativity that scientific inquiry exists. Someone had the wacky creative idea that there should be something that is so strong, and inflammable, and just generally amazing like a super... thing! And tadaaah, we have Kevlar. The stuff in bullet proof vests.
The surface area would be 25cm, while the vloume would be
or length×width×height
125cm cubed
We can rewrite the equation KBr(aq) + AgNO3(aq) → AgBr(s) + KNO3(aq) into its net ionic equation into
K+ + Br- + Ag + + NO3- = AgBr + K + NO3-only aqueous solutions can dissociate. Spectator ions are present in both sides, hence these are K+ and NO3-. THe rules of assigning oxidation numbers is to identify the number of valence electrons of elements and may be arbitrary depending on the charge of the molecule.
Answer:
It is <u>melting</u> which is a physical change.
