THE EXPLINATION ANSWER: I think crude oil is a mixture because it is made up of compounds that can be separated using distillation, a physical process.
Reverse the 2nd reaction,
CO2 + H2 -------> CO + H2O---- i
Now new equilibrium constant will be,
K' = 1/K2 = 10^-5
Adding i and last equation you'll get,
<span>CO2 (g) + 3 H2 (g)----->CH3OH (g) + H2O (g)
K1 = K' x K3 = 1.4 x 10^2 </span>
Synthesis reaction or combination reaction
Answer:
Advances in modern agriculture allow today's farmers to grow in ways that are measurably more sustainable. These practices help farmers retain topsoil and reduce erosion, conserve water in multiple ways, reduce emissions, protect pollinators, and protect natural resources by using farmland more efficiently. Industrialized agriculture is highly concentrated and mechanized, relying on chemical inputs like fertilizers, pesticides and non-therapeutic antibiotics. Agriculture often places significant pressure on natural resources and the environment.
