Answer:
Explanation:
Balance the following reaction. A coefficient of "1" is understood. Choose option "blank" for the correct answer if the coefficient is "1." NH3 + O2 → N2 + H2O
2NH3 + 3/2O2 → N2 + 3H2O
you cannot have 3/2 of a molecules, so multiply all coefficients by "2"
4NH3 + 3O2 → 2N2+ 6H2O
there are 4 N on each side, 12 H on each side, 6 O on each side
the equation is balanced!
when balancing equations, you cannot change the subscripts in the compounds, you can only show with coefficients haw may molecules yous have
It is the reactant that is left after the reaction stops
Ionic is metal and nonmetal
