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.
Polarity? Because that shows what poles each side has or it’s something got to do with alignment of something I don’t quite remember
No. of moles = mass / molecular weight
n = m / Mr
n = 3 g / 23 g/mol
n = 0.13 mol / 4
n = 0.0326 mol
Mr of Na2O = 23+23+16 = 62 g/mol
n = 0.0326 mol x 2 (because you have 2x Na2O) = 0.0652 mol
m = n x Mr
m = 0.0652 mol x 62 g/mol
m = 4.04 g
