Consider the chemical equation below.

mg(oh)2 + 2hno3 --> mg(no3)2 + 2h2o

which is the net ionic equation? (b. is already incorrect.)

a. h^+ + oh^- --> h2o
c. mg^+2 + 2no3^- --> mg^+2 + 2h2o
d. mg^+2 + 2oh^- + 2h^+ + 2no3^- --> mg^+2 + 2no3^- + 2h2o

Nitric oxide (no) can be formed from nitrogen, hydrogen and oxygen in two steps. in the first step, nitrogen and hydrogen react to form ammonia: n2(g) + 2 h_2(g) rightarrow 2 nh_3 (g) delta h = -92. kj in the second step, ammonia and oxygen react to form nitric oxide and water: 4 nh_3(g) + 5 o_2(g) rightarrow 4no(g) + 6 h_2o(g) delta h = -905. kj calculate the net change in enthalpy for the formation of one mole of nitric oxide from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.
