The reaction of ethanol (ch3ch2oh) with aqueous i− in the presence of h+ ions produces the corresponding ethyl halide (ch3ch2i) and reaches completion:

Drug abuse will not lead to physical and psychological dependence. true or false ?

The melting point of sulfur is 115 °c and its boiling point is 445 °c. what state would sulfur be in at 200 °c?

Given the following at 25c calculate delta hf for hcn (g) at 25c. 2nh3 (g) +3o2 (g) + 2ch4 (g) > 2hcn (g) + 6h2o (g) delta h rxn= -870.8 kj. delta hf=-80.3 kj/mol for nh3 (g), -74.6 kj/mol for ch4, and -241.8 kj/mol for h2o (g)
