Asealed flask contains 1.3 x 10^25 molecules of co2. how many moles of co2 are in the flask?

Answer : The moles of in the flask are, 21.58 moles.

Solution :

As we are given the molecules of in the flask are =. Now we have to calculate the moles of in the flask.

As, molecules of present in 1 mole of .

So, molecules of present in moles of .

Therefore, the moles of in the flask are, 21.58 moles.

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 :

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
