Answer:
According to the Environmental Paper Network's Paper Calculator, it takes about 32 million BTUs of energy to produce 1 ton of virgin paper fiber. To produce 1 ton of recycled paper, it takes about 22 million BTUs.
so the answer could be it takes less Btu to manufacture recycled products than new ones
Basis of the calculation: 100g
For Carbon:
Mass of carbon = (100 g)(0.80) = 80 g
Number of moles of carbon = (80 g)(1 mole / 12g) = 20/3
For Hydrogen:
Mass of hydrogen = (100 g)(0.20) = 20 g
Number of moles of hydrogen = (20 g)(1 mole / 1 g) = 20
Translating the answer to the formula of the substance,
C20/3H20
Dividing the answer,
CH3
The molar mass of the empirical formula is:
12 + 3 = 15 g/mol
Since, the molar mass given for the molecular formula is 30.069 g/mol, the molecular equation is,
C2H6
ANSWER: C2H6
Since the atoms or molecules in a solid do not translate hence, the structures of solids usually described in terms of the positions of the constituent atoms rather than their motion.
<h3>States of matter</h3>
There are three state of matter which are;
In a solid, atoms or molecules retain their positions and do not translate, hence, the structure of atoms or molecules are most important in determining the structure of a solid.
Also, the fact that the atoms or molecules in a solid can only vibrate or rotate explains why the structures of solids usually described in terms of the positions of the constituent atoms rather than their motion.

I believe this nuclide is potassium with the symbol K. Atomic number for an element remains constant no matter how the mass changes. From the periodic table, potassium has an atomic number of 19.
