At the temperature of 1450 °c the equilibrium constant of the reaction n2(g) + o2(g) = 2no(g) is kc= 0,0900
calculate the molar concentrations to the equilibrium knowing that the initial mixture contains 1.00 mol of n2 and 1.00 mol of o2 in a volume of 5.00 l.

solutions: (0,142 mol/l; 0,142 mol/l; 0,116 mol/l)

Draw any one of the skeletal structures of a 2° alkyl bromide having the molecular formula of c6h13br and two stereogenic centers. indicate chirality by using wedge and hashed wedge notation. lone pairs do not need to be shown.

Arectangle has a diagonal 20 inches long that forms angles of 60 and 30 with the sides. find the perimeter of the rectangle. for geometry

To find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? a) when more work was done, the couch was moved the same distance. b) when more work was done, the couch was moved less. c) when more work was done, the couch was moved further. d) when more work was done, the couch wasn't moved at all.
