Guida verificata passo dopo passo1
Understand the naming convention for molecular compounds, where prefixes indicate the number of atoms of each element present in the compound.
Identify the prefix 'di-' which means 2, and 'pent-' which means 5, corresponding to the number of nitrogen and oxygen atoms respectively.
Combine the element symbols with their respective prefixes: 'dinitrogen' means 2 nitrogen atoms (N2), and 'pentoxide' means 5 oxygen atoms (O5).
Write the chemical formula by placing the number of atoms as subscripts after each element symbol: N2O5.
Verify that the formula matches the name by checking that the number of atoms corresponds correctly to the prefixes given in the compound's name.
