Gammonium nitrate was the oxidizing agent used that damaged the new york world trade center in 1993 and the federal building in oklahaoma city in 1995. the thermochemical equation for its decomposition is given below. what quantity of heat is evolved from the decomposition of 50.0 kg of ammonium nitrate

  kJ

Explanation:

The thermochemical equation for decomposition of ammonium nitrate is:

Given mass= 50.0 kg =   (1kg=1000g)

According to stoichiometry:

1 mole of gives = 82.1 kJ of heat

Thus of give =  kJ of heat

Thus kJ of heat is evolved from the decomposition of 50.0 kg of ammonium nitrate.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
