How can chemistry be used to solve a real world problem?

Use the table to identify the phase and phase changes of the elements under the given conditions. write the name of the substance, phase, or phase change

What shape would a molecule with two bound groups and two lone pairs have?

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
