Desiré was investigating a chemical reaction. When she heated it up, she found that sulfuric acid (H2SO4) changed into water (H2O). She made the following atomic-scale model to show what she thinks happened. Explain your answer. Describe why the model is either complete or incomplete.

For the reaction shown, calculate how many moles of no2 form when each of the following completely reacts. 2n2o5(g)→4no2(g)+o2(g) part a 1.0 mol n2o5 express your answer using two significant figures. nothing mol m o l request answer part b 5.4 mol n2o5 express your answer using two significant figures.
