As an acid is being added to a base, you first need to calculate what is left after they react. Without doing any calculations, we can already see that the acid is in excess as both solutions have the sam...
A mole is a measure of quantity, such that when you have a mole of something, you have 6.02 x 1023 atoms/molecules of it. The number of atoms/molecules in a mole is called "Avogadro's Numb...
For an acid the formation of a hydrogen ion denotes it as being acidic.HCL -> H+ + CL-Where as for an alkali the formation of a hydroxyl ion denotes is as being alkaliNAOH -> Na+ and OH-
We know that the reaction is a 2:1 ratio as 2 moles of NaNO3 is used to form 1 mole of O2 so first we need to find the moles of the product produced SoVolume of gas (dm3)= number of moles x 24dm3The...
Firstly, let's start off with the simplest type of bonding. Ionic bonding involves the transfer of electrons, usually from a metal (Sodium/Na) to a non-metal (Chlorine, Cl). This creates an attraction bet...
