Nonmetals Assignment Active
Choosing the Appropriate Property
A sample of iodine is easiest to ship as a powder because it is
v. making it easy to break into
small pieces.
Helium is less
than the elements that make up the air we breathe, so a balloon filled with
helium will float in air.
Plastic is a compound of nonmetallic elements, so its
properties make it a popular coating
for electric wires to prevent the current from escaping.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

c (diamond),

sio2 (quartz)
