The element, s (sulfur), undergoes a phase transition from a rhombic form to a monoclinic form at 95.4°c. if δhtransition=0.38 kj mol-1, calculate δstransition under the above conditions. show all working. (ii) monoclinic sulfur is known to melt at 119°c. given δhfusion=1.23 kj mol-1, calculate, showing all working, δsfusion. (iii) given the s occurs as s8 in solid or liquid forms, convert the values of the enthalpy and entropy of fusion above to those expected for s8.

4.25g sample of solid ammonium nitrate dissolves in 60.0g of water in a coffee-cup calorimeter, the temperature drops from 22.0 c to 16.9 c. assume that the specific heat of the solution is the same as that of pure water. calculate delta(h) (in kj/mol nh4no3) for the solution proces.

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
