C2H2, or acetylene, has a molar mass of 26g. That means it has 113/26 = around 4.34 mols. Assuming complete combustion, the balanced equation comes out to this:
C2H2 + 3O2 --> 2H2O + 2CO2
Using the molar ratios, we get that we get 8.68 mols of water for every 4.34 mols, so since the molar mass of water is 18 grams per mol, we multiply 18 * 8.68 = about 156.24 grams.
2KMnO4 + 2FeSO4 + 2H2SO4 ->
K2SO4 + 2MnSO4 + Fe2(SO4)3 + 2H2O
Answer:
4770 grams of sodium carbonate
Explanation:
The reaction that takes place between sodium carbonate and sulfuric acid is:
- Na₂CO₃ (s) + H₂SO₄ (aq) → Na₂SO₄ (aq) + CO₂(g) + H₂O (l)
First we <u>calculate how many H₂SO₄ moles reacted</u>, using the <em>given concentration and volume of solution</em>:
moles = Molarity * Liters
- moles = 18.0 M * 2.50 L = 45 mol H₂SO₄
Then we <u>convert H₂SO₄ moles into NaCO₂ moles</u>, using the <em>stoichiometric coefficients</em>:
- 45 mol H₂SO₄ * = 45 mol NaCO₂
Finally we <u>convert 45 NaCO₂ moles into grams</u>, using its <em>molar mass</em>:
- 45 mol NaCO₂ * 106 g/mol = 4770 g
Answer:
oxygen is colorless, odorless, tasteless and soluble in water
