3NO2 + H2O --> 2HNO3 + NO

How many grams of H2O are needed to produce 45g of NO?.

Using the equation below, calculate the number of grams of N2 that are formed from the reaction of 21 grams of NH3.

4NH3 + 3O2 --> 2N2 + 6H2O

- "the acute form of diverticulitis can manifest itself with one or more severe attacks of infection and inflammation.

the inflammation of diverticulitis can eventually result in a bowel obstruction, which may cause constipation, thin stools, diarrhea, abdominal swelling or bloating, and abdominal pain."

c, liquids evaporate, creating a gas

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
