What is the mole ratio of oxygen to pentane?
The mole ratio of oxygen to pentane in the balanced chemical equation for the combustion of pentane is 13:1. This means that 13 moles of oxygen are required to completely react with 1 mole of pentane.
Will 27 grams of aluminium react completely with 24 grams of oxygen?
No, the reaction will not be complete. The balanced equation for the reaction between aluminum and oxygen is 4Al + 3O2 -> 2Al2O3. To calculate which reactant is limiting, we need to convert the masses of aluminum and oxygen to moles and compare them based on the stoichiometry of the equation.
What is the theoretical yield of aluminum oxide if 2.40 mole of aluminum metal is exposed to 2.10 mol of oxygen?
To determine the theoretical yield of aluminum oxide, we first need to write a balanced chemical equation for the reaction between aluminum and oxygen to form aluminum oxide. The balanced equation is 4Al + 3O2 -> 2Al2O3. From the equation, we can see that 4 moles of aluminum react with 3 moles of oxygen to produce 2 moles of aluminum oxide. Therefore, if 2.40 moles of aluminum is exposed to 2.10 moles of oxygen, the limiting reactant is oxygen. Using stoichiometry, we can calculate the theoretical yield of aluminum oxide, which is 1.60 moles.
What is the molar ratio of hydrogen to oxygen?
The molar ratio of hydrogen to oxygen in water (H2O) is 2:1. This means that for every 2 moles of hydrogen, there is 1 mole of oxygen.
What is the mole ratio of air to methane gas in the cumbustion of methane?
The balanced chemical equation for the combustion of methane is CH4 + 2O2 -> CO2 + 2H2O. This means that the mole ratio of air to methane gas is 2:1, as two moles of oxygen from the air are required to react with one mole of methane gas.
What is the mole ratio of oxygen to pentane?

How if the magnesuim is not polished would the reported mole ratio of oxygen to magnesium be too high too lowor unaffected?
If the magnesium is not polished, there may be impurities or oxides on the surface that could affect the reported mole ratio of oxygen to magnesium. This could result in a higher reported mole ratio due to the presence of excess oxygen-containing compounds on the surface, leading to an inaccurate measurement of the actual ratio of oxygen to magnesium.
What is empirical formula of aluminum oxide?
The empirical formula of aluminum oxide is Al2O3, which indicates that each aluminum atom is bonded to two oxygen atoms. This ratio of aluminum to oxygen atoms is the simplest whole number ratio in which they combine.
How much oxygen in grams will be required to react with 0.5 mole of aluminium?
The molar ratio of oxygen to aluminium is 3:4 in the reaction. So, 0.5 mole of aluminium will react with (0.5 * 3/4) = 0.375 moles of oxygen. Using the molar mass of oxygen (16 g/mol), the mass of oxygen required will be 0.375 moles * 16 g/mol = 6 grams.
If the burning of the magnesium ribbon was out of control would it affect the mole ratio of oxygen to magnesium?
No. According to the law of definite proportions, the mole ratio will always be the same.
What is the molar ratio of hydrogen to oxygen?
The molar ratio of hydrogen to oxygen in water (H2O) is 2:1. This means that for every 2 moles of hydrogen, there is 1 mole of oxygen.
What does al2o3 stand for?
Aluminum oxide has the molecular formula of Al2O3. It is composed of aluminum (Al) and oxygen (O) and is 102.0 grams per mole.
What is the mole ratio of air to methane gas in the cumbustion of methane?
The balanced chemical equation for the combustion of methane is CH4 + 2O2 -> CO2 + 2H2O. This means that the mole ratio of air to methane gas is 2:1, as two moles of oxygen from the air are required to react with one mole of methane gas.
Symbol of Aluminum oxide?
The symbol for aluminum oxide is Al2O3. It is a compound made up of aluminum and oxygen atoms in a 2:3 ratio.
How many moles of oxygen are produced when 26.5 mol of aluminum oxide are decomposed?
When aluminum oxide decomposes, it produces 2 moles of aluminum and 3 moles of oxygen for every mole of aluminum oxide. Therefore, for 26.5 moles of aluminum oxide decomposed, 3 * 26.5 = 79.5 moles of oxygen are produced.
