Experiments with cathode ray tubes led to the discovery of the electron (electrons).
Or I think the t.v
In writing the formula for a salt the symbol of the cation is first then the anion is written second .
Enthalpy is the energy needed for the phase change called vaporization. It is the energy needed to break the bonds of the liquid molecules so that it can be converted to its gaseous form. Therefore, the greater the value of the enthalpy is, the stronger are the bonds of the substance. <em>Therefore, the answer is Aluminum.</em>
I think the correct answer from the choices listed above is option D. <span>When you measure the boiling point of mercury, you are investigating a physical property. Boiling point is a physical property because it involves only a physical change. In boiling, the phase of the substance is only changed not the substance itself is changed.</span>
