The second stage of the ostwald process begins by oxidizing nitric oxide gas in oxygen gas to nitrogen dioxide gas. then, the resulting nitrogen dioxide gas is absorbed by waterto yielding nitric acid hno3(aq) and some nitric oxidegas. these reactions are often carried out at ~50ºc (323 k) and atmospheric pressure. write these two balanced chemical reactions.

we must convert molecules of co₂ to moles and then to grams of co₂.
step 1. convert molecules to moles
moles of co₂ = 4 molecules co₂ × (1 mol co₂/6.022 × 10²³ molecules co₂)
= 6.642 × 10⁻²⁴ mol co₂
step 2. convert moles to grams
mass of co₂ = 6.642 × 10⁻²⁴ mol co₂ × (44.01 g co₂/1 mol co₂)
= 2.923 × 10⁻²² g co₂
the formula for the most stable form of oxygen is o₂, so the subscript is 2.
however, there is a less stable form of oxygen called ozone. its formula is o₃, so the subscript for ozone is 3.
a. as you make more and more of one good or service, you will also make more and more of another.
