This is a simple moles equation and the method with any moles equation is find the number of moles of something, use the chemical equation to work out the number of moles of the thing you need to find and...

First, It would be useful to write the equation for the dissociation of the weak acid HA, which is HA <--> H⁺+ A^-. Then, write the Ka expression of the weak acid HA, which is [...

Giant ionic lattices are regular structures, held together by ionic bonds. These ionic bonds are strong electrostatic forces of attraction between oppositely charged ions, acting in all directions. Energy...

Le Chatelier's principle: If the external condition is changed, the equilibrium will shift to oppose this change. What are these external conditions that can be changed? Temperature, pressure and concentr...

The naturally occurring compound in limestone is calcium carbonate (CaCO₃). When heated, the CaCO₃ thermally decomposes (is broken down by the heat in an endothermic process) to prod...
