Answer: A typical hydrogen fuel cell produces 0.5 V to 0.8 V per cell. To increase the voltage individual cells can be connected in series.
Answer:
When we say "chlorine wants to gain one electron", we speak of the radical atom. Chlorine as a free radical, Cl⋅ , is the chlorine atom that we say has 7 valence electrons and wants its 8th to form an octet. So, Cl⋅ , chlorine radical, is less stable, and Cl− , chlorine ion, is more stable
Given that the liquid conserves the volume, when it is changed from one container to another, the kinetic molecular theory predicts no change in the velocity of the molecules, which means that the temperature will not change.
The answer should be a) always six. The chemical reaction is the process of molecule break down and form again. So the molecule will change but the atom will not change both type and number.
