Question

1. Observe the following equation which shows the action of heat on Calcium Nitrate
2 Ca(NO),+ 2 CaO + 4 NO2 + 0,
a) How many moles of NO are formed when a mole of 2 Ca(NO3), is decomposed ?
b) What is the volume of NO, produced when 164 gm of Ca(NO3), is heated at constant
temperature and pressure ?
c) Calculate the mass of Calcium Oxide formed when 82 gm of Ca(NO3)2 is heated.
d) What is the quantity of Ca(NO3), required to produce 5 moles of gaseous products ?
A.​

Answer 1

Explanation:

WHEN HEATED TO INCANDESCENCE, CALCIUM NITRATE DECOMP INTO /NITROGEN OXIDE, CALCIUM OXIDE AND OXYGEN/. When heated to decomposition it emits toxic fumes of nitroxides
