Ok so N2+O2=2NO and my delta h is 180.5 kJ I need to know. If I react 10 g of nitrous gas with excess oxygen how many grams of Nitrogen monoxide will be produced

21.6 grams

Explanation:

First we convert 10 g of N₂ into moles, using its molar mass:

Then we convert 0.36 moles of N₂ into moles of NO, using the stoichiometric coefficients of the balanced reaction:

Finally we convert 0.72 NO moles into grams, using its molar mass:

you need to have a picture of the atom that way we can answer it
