Jolene wants to experiment with sugar cubes. Which of the following causes a sugar cube to only change physically, not chemically

If you cut the cube and keep all the pieces you are causing only physical change

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.
