A reaction in which A, B, and C react to form products is zero order in A, one-half order in B, and second order in C.
By what factor does the reaction rate change if [A] is doubled (and the other reactant concentrations are held constant)?
By what factor does the reaction rate change if [B] is doubled (and the other reactant concentrations are held constant)?
By what factor does the reaction rate change if [C] is doubled (and the other reactant concentrations are held constant)?
By what factor does the reaction rate change if the concentrations of all three reactants are doubled?
a 30 g sample of water at 280 k is mixed with 50 g of water at 330 k. calculate the final temperature of the mixture
After 273 m3 of ethylene oxide at 748 kPa and 525 K is cooled to 293 K, it is allowed to expand to 1.10 × 103 m3. What is the new pressure?
What is the pH of an acetic acid-potassium acetate buffer if the salt concentration is 40% higher than that of the acid
The compound, an eight-carbon alkane, serves as the 100 octane standard for gasoline. It has five methyl groups, one quaternary carbon, tests negative for C-C double bonds and gives four monochloro substitution products
What are the seven redox reactions of these species of Mn2+?Mn2+ Mn(OH)2 (s) Mn3O4 (s) Mn2O3 (s) MnO2 (s) H2O H+ e-
Aqueous solutions of 30% (by weight) hydrogen peroxide, H2O2, are used to oxidize metals or organic molecules in chemicals reactions. Given that the density of the solution is 1.11 g/mL, calculate the molality, molarity, and mole fraction.
a chemistry student needs of chloroform for an experiment. by consulting the crc handbook of chemistry and physics the
Calculate the number of moles of HCl that would be consumed by 1.0 g of NaHCO3
How do you find the concentrations of the individual reactants that are part of the compounds? As far as the relative rate, I don't understand how to find m, n, and p in the equation: relative rate = k' (I-)^m(BrO3-)^n(H+)^p.
What was the mass percent of dissolved solids in the sea water? b.) The actual solution chloride content in the sea water was 2.69%
A 0.5000-g sample containing NaHCO3, Na2CO3, and H2O was dissolved and diluted to 250.0 mL. A 25.00-mL aliquot was then boiled with 50.00 mL of 0.01255 M HCl. After cooling, the excess acid in the solution required 2.34 mL of 0.01063 M NaOH when t..
this being in excess of the amount needed to neutralize both hydrogens of the H2C2O4. The excess NaOH required 12.62 mL of 0.1251M HClto reach the equivalence point. What was the weight % of H2C2O4 in the sample.
