Molar mass
NH3 = 17 g/mol
N2 = 28 g/mol
4 NH3 + 6 NO = 5 N2 + 6 H2O
4 x 17 g NH3 ------------ 5 x 28 g N2
?? g NH3 --------------- 300 g N2
300 x 4 x 17 / 5 x 28 =
20400 / 140 => 145.71 g of NH3
Nitrogen and hydrogen atoms that make up ammonia (NH3) are held together by polar covalent bonds, where electrons are shared unequally. Nitrogen is significantly more electronegative than hydrogen, so shared electrons spend more of their time orbiting the nitrogen atom.
The isotope of an atom containing 40 protons and 51 nuetrons suddenly has two nuetrons added to it. What isotope is created?
H + ions
Acidic and alkaline solutions can conduct electricity because they have ions that are free to carry charge. Look at the formulae of these acids. They all contain H + ions. When an acid is diluted the concentration of H + ions is decreased and the pH increases towards 7.
