How many moles of n are in 0.221 g of n2o?

0.221 g of have 0.010 mol of N

Explanation:

Mass of

Step 1

Calculation of moles of

Molecular mass of = 14 × 2 + 16 = 44

Calculation of moles of N

1 mol of has 2 moles of N

0.005 mol of will have

                = 0.005 × 2 = 0.010 mol of N

So, 0.221 g of have 0.010 mol of N

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

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 :
