If you have 10 moles of propane and 15 moles of oxygen, how many liters of carbon dioxide would be produced at STP?
Chemical equation: C3H8+5O2 --> 3CO2 + 4H2O. *summoning anyone who knows how to do limiting reactants/ideal gas law stoichiometry (thank u!)

Ahypothrticalax type of ceramic material is known to have a density of 2.10 g/cm3 and a unit cell of cubic symmetry with a cell edge length of 0.57 nm. the atomic weights of the a and x elements are 28.5and 30.0 g/mol, respectively. on the basis of this information, which of the following crystal structures is (are) possible for this material: sodium chloride, cesium chloride, or zinc blende

Type the letter that represents the correct location for each particle type below.

How would the number of moles (n) of o2 change if the atmospheric pressure doubled but all other variables stayed the same
