An acid is a proton donor. The acid molecule may have one or more protons that it can lose depending on its structure, however generally the second proton is much less acidic (meaning that it is lost much...

According to collision theory: Increasing the temperature increases the average energy of the system. This means more molecules have enough energy to overcome the activation enthalpy when they collide, ca...

Mols is a measure of the amount of a molecule present, chemically defined as 1/12th of an atom of carbon 12

Mols = Mass (g) / Molecular Mass (gmol^-1)

Phosphorous has five electrons in its outermost shell of electrons. Fluorine provides three electrons to the phosphorous allowing the formation of a stable central phosphorous atom which now has 8 electro...

Both of these elements are part of the 2nd group of elements on the periodic table. ie in first ionisation, their electron configuration changes from nS2 -> nS1.

Strontium is a much larger eleme...
