An unknown gas, D, reacts with fluorine gas to form the compound DF4(g), as represented by the following equation. D(g)+2 F2(g)→DF4(g) A series of experimental trials were performed at 600∘C to determine the rate law expression for the reaction. Data from the trials are shown below.(a) A student claims that the reaction is first order with respect to F2(g). Do you agree or disagree? Justify your answer using the data above.(b) What is the initial rate of disappearance of F2(g) in trial 3? Justify your answer(c) A student claims that if element D is in group 18, then the molecular geometry of DF4(g) is square planar. Do you agree or disagree with the student? Justify your answer in terms of VSEPR theory.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
