What is the mole ratio of sulfur to oxygen gas when they react to sulfur trioxide? Notice that you have a 2:1 mole ratio between sulfur dioxide, SO2 , and oxygen; this will be very important when comparing the number of moles of each gas that react, since it will tell you if one of the two compounds will act as a limiting reagent.
What is the mole ratio?
A common type of stoichiometric relationship is the mole ratio, which relates the amounts in moles of any two substances in a chemical reaction. We can write a mole ratio for a pair of substances by looking at the coefficients in front of each species in the balanced chemical equation.
Does sulfur react with oxygen?
Sulfur reacts with oxygen to form sulfur dioxide. When nonmetals react with one another, the product is a molecular compound. … Sulfur can also combine with oxygen to produce sulfur trioxide.
Is S 3o2 SO3 balanced?
2 S + 3 ⇒ 2
Finally you have the same amount of sulfur and oxygen on both sides of the reaction. So the chemical equation is finally balanced.
Do you reduce mole ratios?
Finding the Mole Ratio in a Balanced Equation
Find the mole ratio between any two components of a chemical reaction using the coefficients of the chemical formulas. The coefficients are the numbers in front of the formula. … The mole ratio between hydrogen and water is 2:2, but you can reduce this to 1:1.
What is the mole ratio of co2 to o2?
The mole ratio tells you in what exact proportions the reactans will mix and exactly how much products their reaction will produce. In this case, the mole ratio between oxygen and carbon dioxide is 5:3 , i.e. you need 5 moles of oxygen to produce 3 moles of carbon dioxide.
What is the mole ratio of water to oxygen?
The ratio of hydrogen atoms to oxygen atoms used to make water molecules is always 2:1, no matter how many water molecules are being made.
Is sulfur or oxygen a better leaving group?
Answer: Oxygen is more electronegative atom than sulfur. More the electronegative means that the electrons attraction tendency is more. … Thus, sulfur is better nucleophile than oxygen.
What happens when you burn sulfur in oxygen?
Sulfur burns in oxygen to form sulfur dioxide.
What do oxygen and sulfur have in common?
Oxygen Family
Each has six of the desired eight electrons required for the octet in its highest energy level. This means that it takes or accepts two electrons from atoms of other elements to form anions or shares two electrons to form covalent bonds. Oxygen and sulfur are common elements.
What is a balanced equation for the combustion of sulfur?
There are three possible chemical equations for the combustion of sulfur: 2S (s) + O₂ (g) → 2SO (g)
What is the balanced equation of Sulphur dioxide?
Sulfur dioxide is the product of the burning of sulfur or of burning materials that contain sulfur: S + O2 → SO2, ΔH = −297 kJ/mol.
What is the mole ratio of ethanol to water?
Mole fraction of ethanol and water mixture is 0.25.
What is the mole mole ratio of HCl and NaOH?
1 NaOH + 1 HCl → 1 NaCl + 1 H2O (Mole ratio of NaOH to HCl is 1:1) • The concentration of the NaOH was 0.1 M, or 0.1 moles/liter.
How is mol calculated?
- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.
What is the mole ratio of CO2 to c2h2?
The chemical formula tells us the mole ratio. CO2 = 1 CO2 molecule : 1 C atom : 2 O atoms. 1 C12H22O11 molecule: 12 O2 molecules : 12 CO2 molecules : 11 H2O molecules.
What is the mole ratio of water to methane?
This calculation involves solving three sets of proportions: (1) The mass of methane is converted to moles using the gram formula mass, 16 g/mole; (2) The stoichiometric ratio of water to methane, 2:1, is used; and (3) The conversion of the moles of water to mass of water using the gram formula mass, 18 g/mole.
What is the ratio of carbon dioxide or CO2?
The chemical formula tells us the mole ratio. CO2 = 1 CO2 molecule : 1 C atom : 2 O atoms.
What is the ratio of H O in water?
Water molecules feature the combinations of hydrogen and oxygen atoms in a 2:1 ratio.
What is the first step in a stoichiometry problem?
Answer: The first step in most stoichiometry problems is to balance the chemical equation.
Why is OH a bad leaving group?
Alcohols have hydroxyl groups (OH) which are not good leaving groups. … Because good leaving groups are weak bases, and the hydroxide ion (HO–) is a strong base.
IS F a good leaving group?
Exception: Fluorine is a poor leaving group. F⁻ is a small ion. Its high charge density makes it relatively unpolarizable. The leaving group needs to be polarizable to lower the energy of the transition state.
Is Cl or Br a better leaving group?
like you said Br- is bigger than Cl- and can therefore better stabilize the negative charge, making it a better leaving group.
What is burning sulfur used for?
Sulfur is burned or vaporized to control fungus, mites, or insects. When sulfur is burned, it turns into a gas called sulfur dioxide. The gas can mix with moisture on plants to form an acid that can damage plant leaves. Breathing the gas can be harmful to human health.
What happens if you breathe in sulfur?
Inhaling sulfur dioxide causes irritation to the nose, eyes, throat, and lungs. Typical symptoms include sore throat, runny nose, burning eyes, and cough. Inhaling high levels can cause swollen lungs and difficulty breathing.
What does burning sulfur look like?
When burned, sulfur produces a blue flame and sulfur dioxide gas — a common pollutant, according to the Environmental Protection Agency.
