Take the reaction: NH3(g) + O2(g) →NO(g) + H2O(- i.
Write a balanced equation.
4 NH₃ (g) + 5O2 (g) → 4 NO (g) + 6H₂O
Identify the excess reagent, as well as how many grams of the excess reagent will remain when the reaction reaches completion provided 2.5g of each reagent was present at the beginning

Astudent carefully transfers 30 g of water and 30 g of alcohol in a glass tube, forming two layers and filling the tube completely. after sealing the tube, the student mixes the solutions, and notices a bubble that forms in the tube. what is the mass of the contents in the glass tube after mixing?

An object becomes electrically charged when: electrons are created in it electrons from it are destroyed electrons are transferred to it protons from it are destroyed protons are created in it

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
