NaOH is a base and hence it can only be neutralized by an acid.
So it is by HCl, which is an acid.
It is 292.5 m because you do 4.5 hours times 65. (please give me brainliest)
Ba(OH)2 can be neutralized by adding an acid to the solution. We can add HCl to produce:
Ba(OH)2 + 2HCl ===> BaCl2 + 2H2O ; producing a salt BaCl2 and water.
or we can add H2SO4 to produce:
Ba(OH)2 + H2SO4 ===> BaSO4 + 2H2O; producing a salt, BaSO4, and water. <span />
The temperature is held constant at (b) and (d). At these points, the substance is changing states. B is changing from solid to liquid and D is changing from liquid to gas
You multiply 32 by 2, since there are two hydrogens in every water molecule.
