What is the coeficient needed for Al to balance Al plus O2 - Al2O3?
You need 4Al and 3O2 This will give you 2 Al2O3
How many moles of Al203 are formed when 0.78mol o2 reacts with aluminium?
The balanced reaction equation is 4Al + 3O2 -> 2Al2O3. Therefore, 3 moles of O2 reacts with 4 moles of Al to form 2 moles of Al2O3. Since 0.78 mol of O2 is reacted, the number of moles of Al2O3 formed can be calculated using the stoichiometry of the reaction.

What is the theoretical yield of aluminum oxide if 3.60 mol of aluminum metal is exposed to 3.00 mol of oxygen Express your answer with the appropriate units.?
The balanced chemical equation for the reaction between aluminum and oxygen to form aluminum oxide is: 4 Al + 3 O2 -> 2 Al2O3. From the equation, 4 moles of Al react with 3 moles of O2 to produce 2 moles of Al2O3. Since there are 3.60 mol of Al (which is in excess) present and 3.00 mol of O2, 3.00 mol O2 will be the limiting reactant in this case. This will produce 2.00 mol of Al2O3. Therefore, the theoretical yield of aluminum oxide is 2.00 mol Al2O3.
What weight of aluminum may be obatained from 1kg of aluminum oxide?

What is the coefficient on Al when equation is Al O2-Al2O3?
To balance the equation for the reaction of aluminum (Al) with oxygen (O2) to form aluminum oxide (Al2O3), we start with the unbalanced equation: 4Al + 3O2 → 2Al2O3. The coefficient on Al is 4 in this balanced equation, indicating that four aluminum atoms are needed to react with three molecules of oxygen to produce two formula units of aluminum oxide.

What is the chemical equation for the reaction aluminum underwent in the disaster?
The chemical equation for the reaction aluminum underwent in the disaster is 4Al + 3O2 -> 2Al2O3. This reaction produces aluminum oxide (Al2O3) when aluminum (Al) reacts with oxygen (O2) in the air.
Is 4Al 3O2 2Al2O3 exothermic or endothermic?
The reaction 4Al + 3O2 -> 2Al2O3 is exothermic. This is because it releases energy in the form of heat during the reaction. The formation of aluminum oxide (Al2O3) from aluminum (Al) and oxygen (O2) is accompanied by a decrease in enthalpy, resulting in the release of heat energy.
What happens when aluminium and oxygen combine?
When aluminum and oxygen combine, they form aluminum oxide. This process is known as oxidation. Aluminum oxide forms a thin, protective layer on the surface of the aluminum, which helps prevent further corrosion and degradation.
