If the burning of magnesium to form magnesium oxide is incomplete, there will still br some elemental magnesium available to be burned (ie combined with oxygen) and so there will be a measureable amount of mass of magnesium left. Also, the amount of oxygen required to combine with the outstanding mass of magnesium could also be determined.
It is not good conductors of electricity or heat!
Answer:
The 35-watt light bulb does a work of 46200 joules in 1320 seconds.
Explanation:
From Physics we remember the definition of work (
), measured in joules, by the following integral equation:
(1)
Where 
is the power, measured in watts.
If the power is stable in time, then the work can be calculated by the following algebraic equation:
(2)
If we know that 
and 
, then the work done by the 35-light bulb is:
The 35-watt light bulb does a work of 46200 joules in 1320 seconds.
