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:
C
Explanation:
I hope that helps!!! it kinda gave you the answer though
The density of substance that contain 850 milligrams for every Ml is
0.85 g/Cm³
calculation
<em> </em><em>step 1:</em><em>convert 850 Mg to g</em>
<em>that is 1 mg=0.001 g</em>
<em> 850 mg =? g</em>
<em>= (850 mg x 0.001 g)/ 1 mg=0.85 g</em>
<em>step 2: convert Ml to Cm³</em>
<em> that is 1 Ml = 1 cm³</em>
<em>therefore density =</em><em> 0.85 g/Cm³</em>
