Same group = same properties, same # of valence electrons
Same period = same # of atomic orbitals
Answer:
option D = N₂ + 3H₂ → 2NH₃
Explanation:
The reaction in which the nitrogen and hydrogen are reacted to form the ammonia is true.
N₂ + 3H₂ → 2NH₃
In this reaction we can see that one molecules of nitrogen react with three molecules of hydrogen and form two molecules of ammonia.
while the other options are in correct because,
2SO₂ + O₂ → 2SO₃
In this reaction two molecules of SO₂ react with one molecule of oxygen and form two molecules of SO₃.
2H₂S + 3O₂ → 2SO₂ + 2H₂O
In this reaction two molecules of H₂S react with three molecules of oxygen and produced four molecules of product.
SnO₂ + 2H₂ → Sn + 2H₂O
This is also incorrect because three molecules of reactant form three molecules of product.
Answer:
which formula can be used to calculate the molar mass of hydrogen peroxide (H2O2)?
» <u>d.2 x molar mass of H + 2 x molar mass of O</u>
Explanation:
Since we've two hydrogen atoms and two oxygen atoms, we multiply each mass by 2
