Use the standard reaction enthalpies given below to determine ΔH° rxn for the following reaction P 4(g) + 10 Cl 2(g) → 4PCl 5(s) ΔH° rxn = ? Given: PCl 5(s) → PCl 3(g) + Cl 2(g) ΔH° rxn = +157 kJ P 4(g) + 6 Cl 2(g) → 4 PCl 3(g) ΔH° rxn = -1207 kJa) -1835 kJb) -1364 kJc) -1050. kJd) -1786 kJe) -2100. kJ

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.

35. a insulated cylinder of solid gold (k 310 kw/m-k) of radius v2 m and height 5 m is heated at one end until the temperature at each point in the cylinder is given by w(r, y, z) (30 z2)(2-(r2+ y2). determine the rate of heat flow across each horizontal disk given by z 1, z 2, and z 3, identifying which has the greatest rate of heat flow across it.
