potassium positive bromine negative
The salt potassium bromide. The chemical equation is 2 K + Br2 -> 2 KBr.
chlorine plus potassium bromide gives bromine plus potassium chloride. Here is the symbol equation, but remember that the numbers AFTER the symbols should be subscripts. Cl2 + 2KBr = Br2 + 2KCl
The Lewis structure of CH3 starts with a C in the center, representing the Carbon atom. The carbon atom has three dashes and two dots. Connected to each dash is an H, representing the hydrogen atoms.
Potassium plus Water gives Potassium Hydroxide plus Hydrogen
2KI+Br2 ---->2KBr +I2
