When combusted in a bomb calorimeter, a 12.6 g sample of acetylene (c2h2) produced a temperature increase of 16.9 oc. the calorimeter constant for the calorimeter was determined to be 31.5 kj/oc. what is the molar heat of combustion for acetylene?

(apex) when a cup of water is dropped, as the cup falls, the water in the cup falls out true or false?

What type of matter is made of only one kind of atom

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
