What do you predict will be the outcome of their experiment? O A The ferofluid will function normally because magnetite particles will still be formed. . B. The resulting product wvill not exhibit magnetic properties. O C The magnetite particles will precipitate out instead of remaining suspended. O D. The particles formed will be too small and the ferrofluid will not form spikes.Aşağıda verilen reaksiyonları tamamlayınız.hyrw 2o nsn hyapsn sem St.) Calcium oxide is sometimes very challenging to etare n the Oumistry labrortory.This compound reacts with moisture in the air and is converted to calcium hydcokide.
