Molar mass of N = 14 g/molMolar mass of O2 = 32 g/molAdding both masses = 46 g/molActual molar mass/ Empirical molar mass = 138.02 / 46 = 3Now multiplying this co effecient with empirical fomula NO2 = 3(NO2) = N3O6So according to above explanation,D) N3O6, is the correct answer.
Combustion=heat and light
decomposition=taking something away
single means one element changes
and double means two elements change l.
Answer:
The molar mass of Pb(Cr2O7)2 is 639.2 g/mol.
He ability to rust is a chemical property of iron. The metal silver does not rust, but eventually a darker substance called tarnish forms on its surface. The chemical properties of copper cause it to become a blue-green color when it is exposed to air
They have thier own group because because they have traits or metals and nonmetals
