What is the boiling point of propanone if the pressure
on its surface is 48 kilopascals?

The boiling point would be 35 degrees Celsius. 

The answers is a nuclear changes

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
