8 valence electrons are found in noble gases. Since noble gases have 8 valence electrons that means they have a full shell - which makes them unreactive
A hypothesis
-Can be tested
-Is a prediction about the expected outcome of an experiment
-Must be stated in a form that can be either proven or disproven
Your answer is D: All of the above are true
1) Option b: gas pressure.
This is sustainted by the kinetic molecular theory of the gases.
2) Option c: raising the temperature of the gas will increase the pressure if the volumen of the gas and the number of particles are constant.
PV = nRT
If V and n are constant, P is proportional to T, then if T increase P will increase too.
