How many grams of P2O5 are formed from 3.4 moles of O2? SHOW the math below

Based on its chemical properties, identify the position of each chemical family on the periodic table.

In which reaction is precipitation occurring?

)in the deacon process for the manufacture of chlorine, hcl and o2 react to form cl2 and h2o. sufficient air (21 mole% o2, 79% n2) is fed to provide 35% excess oxygen, and the fractional conversion of hcl is 85%. calculate the mole fractions of the product stream components.
