The first ionisation energy is the energy required to remove an electron from each atom in one mole of gaseous atoms to produce +1 charged gaseous ions.The first ionisation energy shows an general increas...

Silicon Dioxide has a macromolecular/giant covalent structure which means it has covalent bonds between all atoms in its structure. Sulfur Trioxide has a simple molecular...

As Sodium is a metal and Chlorine is a non-metal they will undergo an ionic reaction in which Sodium will lose an electron and donate it to the Chlorine atom which will gain an electron. This will create ...

The rate equation of a reaction is useful to describe the relationship between the rate of a reaction and the concentration of its reactants. It is used to determine how a change in the concentration of a...

This question is all about using the mols equation question (mols = mass/molecular weight).
It's best to break it down into steps:
1) calculate the molecular masses of the compounds that are in...
