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:

N₂ + O₂ → 2NO

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

10 g ÷ 28 g/mol = 0.36 mol N₂

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

0.36 mol N₂ * = 0.72 mol NO

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

0.72 mol NO * 30 g/mol = 21.6 g

Both models are effective because they show the valence electrons, and these valence electrons indicate the reactivity of an element.

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
