I have like ten minutes left to submit my homework in A student knows that the sublimation point of carbon dioxide (CO ) is -78.5°C. That is, at this temperature, solid carbon dioxide will change state directly from a solid to a gas. The student is asked to predict the temperature at which gaseous carbon dioxide will change directly from a gas to a solid. Which prediction will be supported by experimental evidence?

See explanation

Explanation:

Even though the options were not stated in the question, it is clear that the prediction required must reflect the stated fact that the sublimation temperature of CO2 is -78.5°C. This is the fact that was observed in the cause of the experiment. Hence any of the options that reflects this statement must be the correct option among the list of options available in the question.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
