What is the difference between a molecular formula and a structural formula? A molecular formula will show the actual number of atoms in a molecule, while the structural formula will show the organization and layout of the atoms in the compound.

A molecular formula will show the smallest whole-number ratio for the different atoms in a compound, while the structural formula will show the actual number of atoms in a molecule.

A molecular formula will show the organization and layout of the atoms in the compound, while the structural formula will show the actual number of atoms in a molecule.

There are three main types of chemical formulas: empirical, molecular and structural. Empirical formulas show the simplest whole-number ratio of atoms in a compound, molecular formulas show the number of each type of atom in a molecule, and structural formulas show how the atoms in a molecule are bonded to each other.

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

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 :
