Periodic tables are given...calculators are allowed too.damn man! really appreciate your work. TANKS A LOT!
btw i wanted to ask that are we provided with periodic table in paper 12,32 and 62 of igcse chem? and are we also allowed to take calculators with us it all three papers? all calculators are allowed or specific models?
Thanks a lot...!!!b) i) because the sewage fungus take in the oxygen for respiration
ii)because the fungus starts to decrease & because the aglae are water plants so they give out CO2 during photosynthesis
c)i)because sewage contains toxic materials and the suspended materials can float on water so they block the light from the algae so they can'y photosynthesis so their level drops
ii)maybe because of overcrowding , less nitrates and maybe because there are fish that feeds on the algae as there is enough oxygen and less suspended solid (toxins)
d) it will kill the algae and the fish ( aquatic organisms )
hope that helps
