Frostbite to the skin and Severe burning to the eyes.
HClO₄ + KOH → KClO₄ + H₂O
HClO₄ - perchloric acid
KOH - potassium hydroxide
That answer is either 3 or 4, but I truly forgot which of the two.
The pH = -log of hydrogen ion concentration
The more acid a solution is the higher is its concentration of H+ ions and the lower is its pH. Acids have a pH lower that 7.
The simple equation used to calculate work is force multiplied by distance, thus as this is the case increasing the distance by a certain amount, assuming the force applied to the object is constant, the amount of work you are doing on the box for instance pushing it, is going to be greater
Since you are pushing the box with the same force covering a greater distance with the force.
