Beginning with 1 m each of co2(g) and h2(g) at 25ºc, which substance will have the highest concentration in an equilibrium mixture?

co2(g) + 4 h2(g) \longleftrightarrow& iff; ch4(g) + 2 h2o(g)

k = 8.2 x 1019 at 25ºc

h2o(g)
ch4(g)
h2(g)
co2(g)

Match the mixture with the substance// i really need on this guys (it’s a pic btw)

If i initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 k, and then i raise the pressure to 14 atm and increase the temperature to 300 k, what is the new volume of the gas?

Sodium nitrite (nano2) reacted with 2−iodooctane to give a mixture of two constitutionally isomeric compounds of molecular formula c8h17no2 in a combined yield of 88%. draw reasonable structures for these two isomers. click the "draw structure" button to launch the drawing utility. place the two compounds in the appropriate boxes below.
