At some temperature, the rate constant for the decomposition of HI on a gold surface is 0.080 mol L^-1 s^-1 : 2 HI(g) H2(g) + I2 → (g) (a) What is the order of reaction?
(b) How long will it take for the concentration of HI to drop from 1.50 mol L^-1 to 0.30 mol ?

(c) The gold surface acts as a heterogeneous catalyst. Describe the four steps involved in this
reaction.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
