C - bc as the water boils the cold water particles melt and become the hot water particles!
Answer:
1)2kclo3=2kcl+3o2
2)2NaCl+F2=2NaF+cl2
3)Pb(OH)2+2HCl=2H2O+PbCl2
4)2Albr3+3k2so4=6kbr+al2(so4)3
5)CH4+2O2=CO2+2H2O
Nylon is a polymer because it is made of a lo of molecules bonded together.
The chemical formulae for copper and sulfur are Cu and S, respectively. The reaction between the elements is,
(1/2)Cu + (1/4)S -->
2Cu + S ---> Cu2S
Thus, the empirical formula of the product is Cu2S.
