The Future of Chemistry
In a 4D universe you would probably instantly die. Heat transfer by particles whacking each other or radiating into the vacuum ought to be far higher, making for a faster rate of surface cooling. The time available for matter to clump and plants and life to form before the place gets too spread out is small. We can't really assume the normal forces exist in higher dimensions - indeed they might be emergent properties of 3 space specifically. An electromagnetic bond is weaker with distance just like gravity, which is bound to impact which molecules are stable and have work properties. It's not a big bang in 2D, but with the same number of particles.
