Answer : The length of a one-dimensional box for an electron is 
Explanation :
The energy level of quantum particle in a one-dimensional box is given as:
where,
= 479 kJ/mol = 479000 J/mol
n = energy level = 1
h = Planck's constant = 
m = mass of electron = 
L = length of a one-dimensional box = ?
Now put all the given values in the above formula, we get:
conversion used : 
Therefore, the length of a one-dimensional box for an electron is
Intensive properties are the properties which values doesnt change with the amount of mass or material that you have, example density, melting point boiling point, molecular mass
Extensive are properties that depends of how much mass or material you have. Example: mass, number of moles, volume, pressure, number of students, population,
mass, volume, quantity (there is only one of each), color, reflect light, temperature, energy
Answer:the mass of the gases and ash should be equal the mass of the initial stack of newspapers, there are equal number of atoms on both sides
Explanation:no matter what form the newspaper would take the mass stays the same because all you did is burn it, conserve means that each atom's mass will stay the same no matter what.
Answer: It is not renewable
Charcoal contains high amount of CO2 emission.
Charcoal when burned emits radiation and even clean coals produces methane.
