Consider the molecules H20, H2S. H2Se, and HzTe. Which do you expect to have the highest boiling
point, and why? (4 points)
KINH20, because it experiences hydrogen bonding.
OH, S, because it dissociates and forms ions.
H2Se, because it experiences ion-dipole forces.
H2Te, because it has the most electrons to form a dipole.

The covalent compound acetylene, which is the fuel of the oxyacetylene torch used by welders, has the molecular formula c2h2. the covalent compound benzene, a commercial solvent, has the molecular formula c6h6 each of these covalent compounds contains carbon and hydrogen atoms in a one-to-one ratio. would it be correct to write the chemical formulas of each as ch? explain.

Consider the following multistep reaction: a b→ab(slow) a ab→a2b(fast)−−−−−−−−−−−−−−−−− 2a b→a2b(overall) based on this mechanism, determine the rate law for the overall reaction. express your answer in standard masteringchemistry format. for example, if the rate law is k[a]3[b]2 type k*[a]^3*[b]^2
