Final answer:
At -133 degrees Celsius, hydrogen chloride (HCl) would be in its solid state, as this temperature is lower than its melting point of -114.8 degrees Celsius.Hal at -133 degrees is in the solid state.
Step-by-step explanation:
The student's question involves determining the state of matter for hydrogen chloride (HCl) at a specific temperature. Given the melting point of HCl as -114.8 degrees Celsius and the boiling point as -85.1 degrees Celsius, we can infer its state at any given temperature. At -133 degrees Celsius, which is lower than both the melting and boiling points, HCl would be in its solid state. Hence, below -114.8 degrees Celsius, HCl is solid; between -114.8 degrees and -85.1 degrees Celsius, it exists as a liquid; and above -85.1 degrees Celsius, HCl is gaseous.
Hal at -133 degrees is in the solid state. Halogens are typically found in the solid state at room temperature, with the exception of Bromine which is a liquid. The melting and boiling points of halogens increase as you move down the periodic table.
