The answer is false. It is because the electron structure of
the atom is not determined by using the direct observation of using an x-ray
but rather the usage of theoretical modeling and the emission spectra will be useful
in observing.
1) The main disadvantage of bio plastics is that when they break down , carbondioxide is released and results into global warming.
2) They are designed to be composted , not recycled.
3) fewer proper composting availability.
4) plants grown for bioplastics have negative impacts of their own.
Density is mass/volume so if you double the mass you would also double the volume which means density would stay the same. Density is the amount of of matter in a given area and it is constant for the substance regardless of differences in mass or volume.
