Given the following at 25c calculate delta hf for hcn (g) at 25c. 2nh3 (g) +3o2 (g) + 2ch4 (g) > 2hcn (g) + 6h2o (g) delta h rxn= -870.8 kj. delta hf=-80.3 kj/mol for nh3 (g), -74.6 kj/mol for ch4, and -241.8 kj/mol for h2o (g)

Elaborate on the reason(s) that matter is said to move even as in a solid state. select one: a. the particles are bound through intermolecular forces but are able to move past each other with relative freedom. b. the particles have sufficient energy to become an ionized gas and are in the most common state of matter in the universe. c. the particles are not able to move out of their positions relative to one another, but do have small vibrational movements. d. the particles are not bound to one another, move quickly, have a low density, and are able to spread apart from one another if unconstrained.

The table below shows a comparison of the different gas laws. some cells have been left blank. name variables constants equation boyle's law pressure, volume ? pv = k charles’s law volume, temperature ? v = kt ? temperature, pressure volume, moles of gas p = kt ? pressure, temperature, volume ? which are assumed to be constant while using the combined gas law? 1. pressure 2. number of moles 3. volume and moles of gas 4. pressure and temperature
