Potassium is a reactive element. Bromine is a reactive element. Write the complete balanced chemical equation using appropriate chemical symbols for the reaction when potassium reacts with bromine to make a solid product showing correct symbols and states of reactants and products.
2K(s) + Br2(?) --> 2KBr(s)
Is this correct? I am not sure what the state of matter is for Br2.
The equation is correct. Br2 in the elemental state is a liquid. It vaporizes easily and boils about 60C.
Yes, your balanced chemical equation is correct. The state of matter for bromine (Br2) is typically a liquid at room temperature and atmospheric pressure. Hence, the symbol for bromine in the balanced equation should have an (l) to represent the liquid state.
Therefore, the complete and balanced chemical equation for the reaction between potassium and bromine, showing the correct symbols and states of reactants and products, is:
2K(s) + Br2(l) --> 2KBr(s)
Here, (s) represents solid and (l) represents liquid.
