Boron triiodide (BI₃)melts at 49.9 °C and boils at 209.5 °C at a constant pressure of 1 atm. What state of matter must a sample of boron triiodide be in at 100°C and 1 atm? A)liquid B)gas C)solid D)solid and liquid in equilibrium E)liquid and gas in equilibrium

Quizplus · Accepted Answer

At 100°C and 1 atm, boron triiodide is below its boiling point of 209.5 °C but above its melting point of 49.9°C. This means that it is in a temperature range where it can exist in either solid or liquid form. However, since the question asks for the most likely state of matter, we can eliminate choices B, D, and E since they represent states that would not be as likely as either solid or liquid at this temperature and pressure. Therefore, the best choice would be A) liquid, as boron triiodide would more likely be in liquid form at this temperature and pressure.
