Consider the following unbalanced equation: C2H5OH(g) + O2(g) → CO2(g) + H2O(l)
1.86 g of ethanol reacts with 10.0 g of oxygen. What is the total volume of gas present (in L) after the reaction is complete, assuming the reaction takes place at 1.00 atm and 25°C?

The total volume of gas present (in L) : 14.04 L

Reaction(balanced) :

C₂H₅OH(g) + 3O₂(g) → 2CO₂(g) + 3H₂O(l)

mol C₂H₅OH(MW=46,07 g/mol) :

mol O₂(MW=32 g/mol) :

Limiting reactant :

mol CO₂ =

mol O₂(unreacted) :

Conditions at T 25 ° C and P 1 atm are stated by RTP (Room Temperature and Pressure). Vm(molar volume) in this condition = 24 liters / mol

Total volume of gas :

volume O₂+volume CO₂ =

they vary. it used to be meat, grain, bread, candy, beverages, donuts, and fruits/vegetables. now they added exercise in.

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
