How many moles of water are in propane?

four moles
Explanation: Clearly, four moles of water result from each mole of propane.

What is the mole to mole ratio of water to propane?

A balanced equation gives you the ratio of products to reactants; for every 1 mole of propane we get 4 moles of water. So the answer is going to be our moles of propane times 4.

How many moles of H2O will be produced?

Two moles
Two moles of H2O, water makes two moles of hydrogen gas and oxygen here. If there’s no coefficient in front of the oxygen, in front of one of these chemicals, we know that it’s really one. That it means one mole.

What is produced in the combustion of propane?

Propane undergoes combustion reactions in a similar fashion to other alkanes. In the presence of excess oxygen, propane burns to form water and carbon dioxide. Complete combustion of propane produces about 50 MJ/kg of heat.

How many moles of propane were burned?

The molar mass of propane is 44 g/mole, so burning propane will release (2030kJ/mole) / (44g/mole) = about 46 kJ/g of fuel burned….ANSWERS TO HOMEWORK #1 – THE WHOLE THING.

CH4 C3H8
kJ released per gram of fuel used 51 46

How many moles of propane do you need to burn in order to make 20 moles of water?

  1. Balanced equation:
  2. C3H8 + 5O2 → 3CO2 + 4H2O.
  3. Use stoichiometry to calculate how many moles of water can be produced from the complete combustion of 5 moles of propane.
  4. Multiply 5 moles C3H8 by the mole ratio between C3H8 and H2O so that moles C3H8 cancel, leaving moles H2O.
  5. 5 mol C3H8 × 4 mol H2O/1 mol C3H8 = 20 mol H2O.

What is the mole ratio between H2O and HBR?

Next, use the 2:2 mole ratio that exists between hydrobromic acid and water to determine the theoretical yield of the reaction, i.e. how much water would be produced if the reaction had a 100\% yield.

What is Mole to mole ratio?

The mole ratio is the ratio of moles of one substance to the moles of another substance in a balanced equation. Use of mole ratios allows us to convert from one chemical substance to another.

How many moles of water are in 2H2O?

Explanation: The equation says that for every 1O2 , there are 2H2O produced. Therefore, if you have 2.2O2 , you must have 2.2⋅2H2O , or 4.4 moles of H2O .

How many moles of H2 are needed to produce 9.10 moles H2O?

Therefore 0.25 mol of H2 is produced.

How much water is produced from burning propane?

Burning a gallon of propane (91,502 BTUS) will produce 1.64 pounds of water. 1,000,000 BTUs of propane will produce (1.64 x 11) gallons of water or about 18 U.S. gallons.

What happens when propane reacts with water?

(iii) Action with water: Propane reacts with water in the presence of mineral acid to form propan-2-ol.

How do you make 4 moles of water from 1 mole propane?

So you working equation becomes: $$\\ce{C3H8 (g) + 2O2 (g) -> C (s) + 4H2O (g)}$$ So you need twice the number of moles of oxygen than propane, to produce four times as many moles of water than you had propane.

How many moles of carbon dioxide are produced when propane is burned?

This tells you that when 1 mole of propane undergoes combustion, 3 moles of carbon dioxide are produced. You can thus say that when 2.0 moles of propane react, you will get

How many moles are required to completely react with NH3?

not present Find: mol NH3 mol NH3 molar Moles Moles and Chemical Reactions f you have 1.0 mole many will be required to required to completely react all of the

Is the complete combustion equation correct?

Yes the complete combustion equation is correct as you stated and the equation of the incomplete combustion is certainly one possibility.
