The rate of chemical reactions depends on the temperature, concentration of the reactants, size of the particles reacting and whether there are any catalysts present.

When the temperature is increa...

The reducing ability of halide ions increases as we go down the group because the size of the ions increases down the group meaning the outer shell electron that gets lost when the ion is oxidised is furt...

The sodium potassium pump (sodium potassium ATPase) is an enzyme found in the membrane of all animal cells. Its job is to move NA+ out of the cell and K+ in the cell against their concentration gradient. ...

A series of compounds with the same functional group, having similar chemcial properties and reactions.

Let’s look closer at the sodium atom. Really close, so we could see. Atom is a neutral species, with 11 protons in the nucleus. We can find that information in the periodic table. 11 proton charge should ...
