Hallo,
ich habe Probleme bei folgender Aufgabe:
Complete the following description of an experiment by putting the verbs given in brackets into the appropriate form, either active or passive.
A small amount of white solid ammonium chloride (place in an evaporating dish). A funnel (invert) over it. The dish (heat) gently. A white vapour (observe). The white vapour (rise). White crystals of ammonium chloride (form) on the inner surface of the funnel. No liquid stage (observe). It (conclude) that ammonium chloride (change) from a solid to a gas and from a gas to a solid directly with no liquid stage.
Hier meine Lösung:
A small amount of white solid ammonium chloride placed in an evaporating dish. A funnel has been inverted over it. The dish heated gently. A white vapour observed. The white vapour rised. White crystals of ammonium chloride formed on the inner surface of the funnel. No liquid stage observed. It concluded that ammonium chloride changed from a solid to a gas and from a gas to a solid directly with no liquid stage
Es wäre sehr nett, wenn mal jemand drüber schauen und mir seine Meinung dazu sagen könnte 
Vielen Dank ;-) |
