Match the specific molecular orientation with the correct type of phase. a. The molecules are aligned so that their long axes run parallel to other molecules within the same layer, but the alignment direction is rotated from one layer to another, forming a spiral pattern. b. The molecules are aligned along their long axes, but they are not packed into layers. c. The molecules are arranged randomly and have no particular orientation. d. The molecules are aligned along their long axes and are packed into layers.

Can anyone explain 1. review your spectrometry data and use the known elements to identify the star's composition. which unknown elements make up this star? justify your element selections. 2. in parts i and ii of the lab, what happened to the electrons of each element to produce the different colors of light? explain your answers using important terms from the lesson and information provided in the laboratory. 3. stars composed of heavier (more massive) elements are often slightly older than stars made predominantly from hydrogen and helium. based on your data, is the newly discovered star a younger star? explain your answer.
