In diesel engines, the chemical energy in the fuel is changed to heat energy, causing the pistons to expand via mechanical energy. The mechanical energy is finally converted to kinetic energy, which is observed as the movement of the vehicle.
Answer: 0.0257 moles of 
and 0.0257 moles of 
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
moles of 
The balanced reaction for dissociation will be:
According to stoichiometry:
1 mole of 
gives 1 mole of and 1 mole of
Thus there will be 0.0257 moles of and 0.0257 moles of
Answer:
Look for extra things to do, small details, until you find a big enough one to go off that to continue
Explanation:
n/a
Closed system. If the system is not closed, matter or energy can escape from the system. an example of this is if you react magnesium and hydrochloric acid in a open system. The H₂ gas is going to escape making it look like some of the mass disappeared . in that same reaction some in an open system will also loose heat to the surrounding which will make it look like less heat was produced.
