For the reaction So3 + H2O -> H2SO4, how many grams of sulfur trioxide are required to produce 4.00 mol of sulfuric acid
1 answer:
Answer:
320 grams of sulfur trioxide are required to produce 4.00 mol of sulfuric acid.
Explanation:
The balanced reaction is:
SO₃ + H₂O → H₂SO₄
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
- SO₃: 1 mole
- H₂O: 1 mole
- H₂SO₄: 1 mole
Being the molar mass of each compound:
- SO₃: 80 g/mole
- H₂O: 18 g/mole
- H₂SO₄: 98 g/mole
By reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
- SO₃: 1 mole* 80 g/mole= 80 grams
- H₂O: 1 mole* 18 g/mole= 18 grams
- H₂SO₄: 1 mole* 98 g/mole= 98 grams
Then you can apply the following rule of three: if 1 mole of sulfuric acid is produced by the reaction of 80 grams of sulfur trioxide, 4 moles of sulfuric acid is produced from how much mass of sulfur trioxide?
mass of sulfur trioxide= 320 grams
<u><em>320 grams of sulfur trioxide are required to produce 4.00 mol of sulfuric acid.</em></u>

Answer:
No. While gold would not react with a silver nitrate solution, nickel would.
Explanation:
Refer to the metal reactivity series.
Reactivity: .
Gold is positioned after silver in the reactivity series, meaning that gold is typically less reactive than silver. Thus, gold would not react with a solution of silver ions to produce silver metal.
However, since nickel is positioned before silver in the reactivity series, it is expected that nickel would react with silver ions in this solution to produce silver metal.
Thus, if the silver nitrate solution comes into contact with the two rings, the nickel ring would likely react with the solution, the gold ring would not.
