Simple 6L of air times the .21L of O2 = 1.26
I think the correct term to fill in the blank would be equal. According to the law of conservation of mass, when sodium, hydrogen, and oxygen react to form a compound, the mass of the compound is equal the sum of the masses of the individual elements. This particular states that the mass cannot be created nor destroyed. So, for every process, the total inflow of mass should be the same total mass for the outflow since mass should be constant all through out. So, for a reaction, the total mass of the reactants should be equal to the total mass of the products.

CO2 is not polar as in this case the same types of molecules
are pulling in the same as well as opposite direction. CH4 is also not polar as
there is no imbalance in the charge of the molecules. CBr4 is also not polar
because in this case also no imbalance in the molecular charges can be seen.
CHBr3 is a bit polar in nature because it has different kind of charges at its
opposite ends. S among the all 4 options CHBr3 is polar.
