Answer:

2 C₄H₁₀(l) + 13 O₂(g) ⇄ 8 CO₂(g) + 10 H₂O(g)

Explanation:

When a substance burns we talk about a combustion reaction. When combustion is complete the products are carbon dioxide and water, like in this case. The equation is:

C₄H₁₀(l) + O₂(g) ⇄ CO₂(g) + H₂O(g)

First, we balance the element with the largest stoichiometric coefficient (C).

C₄H₁₀(l) + O₂(g) ⇄ 4 CO₂(g) + H₂O(g)

Then, we balance H because it is in just 1 compound on each side.

C₄H₁₀(l) + O₂(g) ⇄ 4 CO₂(g) + 5 H₂O(g)

Finally, we balance O.

C₄H₁₀(l) + 6.5 O₂(g) ⇄ 4 CO₂(g) + 5 H₂O(g)

Since we want the smallest whole numbers, we multiply all coefficients by 2.

2 C₄H₁₀(l) + 13 O₂(g) ⇄ 8 CO₂(g) + 10 H₂O(g)

this is the chemical formula for methyl tert-butyl ether (the clean-fuel gasoline additive mtbe):a chemical engineer has determi
Alex17521 [72]

The Number of moles required for MTBE is 2 as per molarity based chemistry theories.

  1. A flammable liquid with a distinct, unpleasant smell is called methyl tert-butyl ether (MTBE).
  2. Since the 1980s, it has been added to unleaded gasoline as a fuel additive to promote more effective burning.
  3. It is created by mixing chemicals like isobutylene and methanol. Gallstones can be removed with MTBE as well.
  4. In this type of treatment, surgically inserted special tubes are used to deliver MTBE directly to the gall bladders of the patients.
  5. Methyl tert-butyl ether is a colorless liquid with a distinct anesthetic-like smell. Vapors are narcotic and heavier than air. 131 °F boiling point. 18 °F is the flash point.
  6. It is miscible in water and less dense than water. Boosts the octane of gasoline.
  7. Therefore it has 2 moles of oxygen.

How much mass (in grams) is in a 3.25 mol sample of NH4OH?
Sergeeva-Olga [200]

Answer:

114 grams

Explanation:

1. NH4OH molecular weight: The molar mass of NH4OH = 35.0458 g/mol...

2. Convert grams-NH4OH-to-moles or moles-NH4OH-to-grams. Molecular weight calculation: 14.0067 + 1.00794*4 + 15.9994 + 1.00794.
