When iron is exposed to oxygen it rusts or oxidizes. which of these represents the balanced equation for this chemical change? a) fe + o → feo b) feo → fe + o c) fe + o2 → fe2o3 d) 4fe + 3o2 → 2fe2o3

What is binding energy and separation energy

Two identical 82 mg dust particles very far apart (pee 0) are moving directly toward each other at a speed of 3698 m/s. the charge on each is-719 ? c. determine how close they will get to each other. let k = 9x109 n-m2/c2 & ignore gravity.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.
