There are three sets of sketches below, showing the same pure molecular compound (ammonia, molecular formula NH3) at three different temperatures. The sketches are drawn as if a sample of ammonia were under a microscope so powerful that individual atoms could be seen. Only one sketch in each set is correct. Use the slider to choose the correct sketch in each set. You may need the following information: melting point of NH3: -77.7 °C boiling point of NH3: -33.3 °C A B 63. °C (Choose one) (Choose one) (Choose one) -55. °C C X 3 -98. °C OU Ar
