Both the batteries and fuel cells are portable resources, which transforms the chemical energy into electrical energy.
A battery will produce electricity from the energy it has accumulated inside the battery, while a fuel cell produces the electricity from the fuel in an external fuel tank. This signifies that while a battery may run dead, a fuel cell will produce electricity as long as there is a supply of fuel.

When a theory is disproved by other further evidence, it is just proper to look for new data to support the theory until it is proven otherwise. It cannot be considered a failure right away but cannot be part of the scientifi knowledge too and more not to become a law.
<u>Answer:</u>
<em>That oxidation number of chlorine is -1 while that of oxygen is -2</em>
<u>Explanation:</u>
When it comes to manganese chloride to stabilize the chlorine Ion. Two manganese ions shall be required. Hence the formula for the compound becomes 
while the formula for manganese (iv) chloride will be 
similarly.
When oxygen and magnesium oxide is considered the Two ions of Manganese will satisfy to ions of oxygen. Which cancels and becomes 
while for manganese (iv) oxide the formula becomes 
.
No, ammonium chloride in water is not a physical reaction. It is a chemical reaction. Hope this helps!
