You multiply 32 by 2, since there are two hydrogens in every water molecule.
Hmm. This is very unspecific but it could either be indicating the pH of the solution or just saying it is an aqeous solution.
The answer would be D because from my research it's the only one that didn't have a catalyst
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.
Density = mass/volume
We are given a mass (which I am assuming is in kilograms) and a volume. Divide to find density.
Density of Saturn = 5.69x10²⁶ kg / 8.01x10²³ m³
Density of Saturn = 710. kg/m³
The density of water is 1000 kg/m³, which is higher than the density of Saturn. Since Saturn has a lower density than water, theoretically, Saturn would float in a gigantic bathtub filled with water.

Answer:</h3>
Density: 710. kg/m³
Float? Yes.
