For the reaction NH4Cl (s)→NH3 (g)  + HCl (g) at 25°C, ΔH = 176 kJ/moland ΔS = 0.285 kJ/(mol - K). What is the ΔG, and will this reaction be spontaneous in the forward direction?
169 kJ/mol; no

91 kJ/mol; no

91 kJ/mol; yes

-91 kJ/mol; yes

c.

explanation:

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
