For the reaction \rm A + B + C \rightarrow D + E, the initial reaction rate was measured for various initial concentrations of reactants. The following data were collected:Trial [\rm A](M) [\rm B](M) [\rm C](M) Initial Rate(M/{\rm s})1 0.10 0.10 0.10 3.0 \times 10^{-5}2 0.10 0.10 0.30 9.0 \times 10^{-5}3 0.20 0.10 0.10 1.2 \times 10^{-4}4 0.20 0.20 0.10 1.2 \times 10^{-4}
What is the reaction order with respect to \rm A?Can the same method be used to find reaction order of B and C?

What might one do to verify that the global strain-energy minimum has been identified
The molar absorptivities for methyl red in its acid form are 44640 M^-1cm^-1 @ 524 nm and 3860 M^-1cm^-1 @ 425nm and for methyl red in its base form are 740 M^-1cm^-1 @ 524nm and 18530 M^-1cm^-1 @ 425nm
One bit of evidence that the present theory of atomic structure is "correct" lies in the magnetic properties of matter. Atoms with unpaired electrons are attracted by magnetic fields and thus are said to exhibit paramagnetism.
Calculate the pH when 27.6 mL of 0.048 MHCl is added to 100.0 mL of the above buffer.
A coin dealer, offered a rare silver coin, suspected that it might be a counterfeit nickel copy. The dealer heated the coin, which weighed 18.0 g to 100°C in boiling water and then dropped the hot coin into 26.5 g of water at T = 16.5°C in an insu..
Compound A is unchanged when treated with dilute base, but treatment of A with concentrated NaOH and heat gives a new compound B (C10H19N) that decolorizes Br2 in CCl4. Compound B is identical to the product obtained from the reaction sequence bel..
