POH = pKb + log [salt] / [base] ---> Basic Buffer
and pH = 14 - pOH
to predict the relative concentrations of the buffer components you need to know both pKb and pH...
While in this case only pKb is given and the pH of buffer is not given. So, nothing can be concluded about the relative concentrations of CH₃NH₂ and CH₃NH₃Cl
It all depends on if you know the mass number and atomic number then you will be able to find out what the amount of neutron in an element.
Electromagnetic radiation is a form of energy that propagates as both electrical and magnetic waves traveling in packets of energy called photons. There is a spectrum of electromagnetic radiation with variable wavelengths and frequency, which in turn imparts different characteristics.
This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space. ...
Ernest Rutherford's gold foil experiment was when he shot positively charged particles at a thin layer of gold foil. He concluded that there was a core that contained most of the atom's mass, the core is the nucleus
