4 NH3 +5 02 +4NO + 6H2O
When 70.25 grams of NH3 react, how many moles of H20 are produced?

6.19 mol H₂O

Explanation:

First, we convert 70.25 grams of NH₃ into moles, using its molar mass:

Then we convert 4.13 moles of NH₃ into moles of H₂O, using the stoichiometric coefficients of the balanced reaction:

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

gas

explanation:

smoke is the matter of a gas
