2. A chemist mixes lead (II) nitrate and potassium iodide solutions (both of which are clear
liquids). A yellow precipitate appears in the final solution. The remaining liquid is an ionic
solution. Solid precipitates containing lead are always yellow. (2 points)

For the reaction, 4 a(g) + 3 b(g) => 2 c(g), the following data were obtained at constant temperature. experiment initial[a],mol/l initial [b],mol/l initial rate,m/min 1 0.200 0.150 5.00 2 0.400 0.150 10.0 3 0.200 0.300 10.0 4 0.400 0.300 20.0 which of the following is the correct rate law for the reaction? 1. rate = k[a]2[b]2 2. rate = k[a][b] 3. rate = k[a]2[b] 4. rate = k[a][b]2

Atoms contain subatomic particles called protons and neutrons. when these protons and neutrons spilt, a lot of energy is released

Why does ammonia, nh3, behave as a base when it reacts with an acid? z
