In acidic solutions you have H+ but in basic solutions you have OH-.
You need know that for to balance the reaction.
<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles. We do as follows:
</span>10 mol NH3 ( 6.022 x 10^23 molecules / 1 mol ) = 6.022x10^24 molecules NH3
Foreshocks and aftershocks can happen at the same time is not true.
