The reaction of NaOH and HCl follows: NaOH +HCl ⇒NaCl + H2O.
So the ratio between the reactants is 1:1.
The moles of NaOH needed to neutralize the acid = volume of NaOH solution * concentration of NaOH solution = 0.0685 L * 0.154 M = 0.01055 mole.
Therefore 0.01055 moles of HCl is presented in the acid solution.
The concentration of HCl solution = moles of HCl/volume of HCl solution = 0.01055mole/0.025L = 0.422 M
Answer:
because I told them to do.
Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.
Answer:
Albert Einstein is perhaps most famous for introducing the world to the equation E=mc2. In essence, he discovered that energy and mass are interchangeable, setting the stage for nuclear power—and atomic weapons. His part in the drama of nuclear war may have ended there if not for a simple refrigerator.
