I WILL RATE BRAINLIEST! NEED HELP!!!!
Barium hydroxide (Ba(OH)2) and sulfuric acid (H2SO4) react to produce water and barium sulfate (BaSO4). Write and balance the equation.


-------Ba(OH)2 + H2SO4    2H2O + BaSO4


2BaOH + H2SO4   H2O + Ba2SO4


BaOH + H2SO4   2OH + BaSO4


2Ba(OH)2 + H2SO4     H2O + Ba2SO4

I think it is the first one but I am unsure....
