1 mol of octane (C8H18) reacts with 25 mol of oxygen (O2) to produce 8 mol of CO2 and 9 mol of H2O. Therefore, 0.74 mol of oxygen can react with 0.0744 mol of octane.
That grade of gasoline has too much octane.
To determine how much octane is left after a reaction, you would need to know the initial amount of octane, the stoichiometry of the reaction, and the amount of other reagents/reactants consumed during the reaction. Without this information, it is impossible to provide an exact answer.
The amount of oxygen reacting with copper can be determined by the reaction stoichiometry. For example, in the reaction of copper with oxygen to form copper oxide, two moles of oxygen react with one mole of copper. From the given amount of copper and assuming all the copper reacted to form copper oxide, you can calculate the corresponding amount of oxygen that reacted with the copper.
They dont love each other so much. Actually Ge is readily oxidized to GeO2 by Oxygen. GeO2,not Ge ,dissolves into water 4.5gram in 1000 gram water.
When hydrogen and oxygen gases react to produce water, 285.5 kJ of energy is released per mole of water formed. To calculate the energy released when 15.0g of water is produced, you first need to determine the number of moles of water produced, then multiply by 285.5 kJ/mol to find the total energy released.
There is no octane in gasoline... it is the equivalent of octane.

That grade of gasoline has too much octane.
Three atoms of oxygen are required to react with each two atoms of aluminum to form the most common product of reaction between oxygen and aluminum. Therefore, 0.75 mole of oxygen atoms will be required to react with 0.5 mole of aluminum atoms. The atomic weight of oxygen is 15.999; therefore, the mass will be (0.75)(15.999) = 12 grams of oxygen, to the maximum possibly justified number of significant digits.
The magnesium has reacted already with as much oxygen that it can (1 atom of oxygen to 1 atom of magnesium). There are no spare magnesium atoms left so the reaction has stopped, There is no energetically favourable way that further oxygen atoms can react.

This really depends upon the kind of gas you are talking about. Nitrogen is a gas, and it does not react with oxygen at normal temperatures. Methane does react very readily with oxygen, although even then, you would need some kind of spark to set it off. A methane oxygen mixture does not so much burst into flames, as explode. It would burn all at once.
Octane gas weighs about 6.073 to 6.296 pounds per gallon, depending on its specific gravity and temperature.
