Consider the equilibrium system described by the chemical reaction below, which has a value of Kc equal to 280 at a certain temperature. If 0.400 mol of IBr is allowed to reach equilibrium in a 3.00 L container, what will the equilibrium concentration of IBr be?. (g) + Br2(g) = 2 IBr(g) 2 3 NEXT > Based on the given values, set up ICE table in order to determine the unknown. 12(g) Br2(g) 2 IBr(g) Initial (M) Change (M) Equilibrium (M) 5 RESET 0.400 0.133 +2r -2x 0.400 +x 0.400 + 2x 0.400 - x 0.400 - 2r 0.133 +x 0.133 + 2r 0.133 -x 0.133 - 2r 1L

please help and explain

Complete the following partial ICE tables. (a) change (b) 2SO3(9) =2SO2(g) + O2(g) +x change CH4(g) + H2O=CO(g) + 3H2(g) +x

Image: Graph, Energy on X axis, Temp on Y axis. There is a line sloping up and to the right labelled "A" beginning near bottom of Y-axis. At end of this line, there is a horizontal line labelled "B". At the end of this line there is another line sloping up and to the right labelled "C". End of Image. NH3 (MW = 17.034 g/mol) Melting point = minus 77.73 degrees C Boiling point = minus 33.34 degrees C Heat capacity of liquid = 4.700 J/g/K Heat capacity of gas = 2.060 J/g/K Heat of vaporization = 23.40 kJ/mol Find A, B and C (as far as 0 degrees C) and the total energy required (in that order) in Joules (express as 'J'). Assume 100.0 g of substance. A, B and C should have four significant figures. When entering your values import your answer followed by a space then J Example: 3450. J Notice that in this particular example a decimal point was included after 3450 to indicate that the zero is significant. If the answer does not need a decimal do not include one. 1.____ 2.____ 3.____ 4.____

In aqueous salt water solution, the forces between sodium ions, chloride ions and water molecules may best be described as: a) ionic bonds b)  covalent bonds   c)  Van Der Waals forces   d)  ion-dipole forces

So these ICE charts are a killer for me. I seem to be understanding every it these so please show you work a little but not to much. Thank you
