Химия: How many grams of benzene can be prepared from acetylene which is obtained from 600 g of 80 % calcium carbide?

Msirinaaa · Accepted Answer

1)2Al+6H2O=2Al(OH)3+3H2
2Al(0)+12H(+)+6OH(-)=2Al(OH)3+3H2
2Al(0)+12H(+)+6OH(-)=2Al(OH)3+3H2
Al-восс-ль, H2O (H(+))-ок-ль
2)BaO+H2O=Ba(OH)2
3)BaO+H2SO4=BaSO4+H2O
Ba(2+)+O(-2)+2H(+)+SO4(-2)=BaSO4+H2O
Ba(2+)+O(-2)+2H(+)+SO4(-2)=BaSO4+H2O
4)2Al+6H2SO4=Al2(SO4)3+3H2
2Al(0)+12H(+)+6SO4(-2)=2Al(3+)+6SO4(-2)+3H2
6H(+)=3H2
Al-восс-ль, H2SO4 (H)-Ок-ль
5)2Al+6H2SO4=Al2(SO4)3+3SO2+6H2O
2Al(0)+12H(+)+6SO4(-2)=2Al(+3)+3SO4(-2)+3SO2+6H2O
12H(+)+3SO4(-2)=3SO2+6H2O
Al-восс-ль, H2SO4 (S)-Ок-ль
6)2NaOH+H2SO4=Na2SO4+2H2O
2Na(+)+2OH(-)+2H(+)+SO4(-2)=2Na(+)+SO4(-2)+2H2O
2OH(-)+2H(+)=2H2O
7)2Al+2NaOH+6H2O=2Na[Al(OH4)]+3H2
2Al(0)+2Na(+)+2OH(-)+6H2O=2Na(+)+2Al+8OH(-)+3H2
6H2O=6OH(-)+3H2
Al-восс-ль, H2O (Н) - ок-ль
