The following reaction is a single-step, bimolecular reaction: CH3Br + NaOH ----> CH3OH + NaBr When the concentrations of CH3Br and NaOH are both 0.115 M, the rate of the reaction is 0.0060 M/s. A. What is the rate of the reaction if the concentration of CH3Br is doubled? B. What is the rate of the reaction if the concentration of NaOH is halved? C. What is the rate of the reaction if the concentrations of CH3Br and NaOH are both increased by a factor of five?

what are the electronic configurations of Pb and Pb2+, also Mo and Mo2+. please explain what are their valence electrons.
If 6.06 L of O2 gas is collected over water at 250C (vapor pressure = 23.8 torr) and a barometric pressure of 702 torr, what is the mass of H2O2 (MM = 34.02 g/mole) decomposed?
Describe the pH of a buffer solution consisting of 100 mL containing 0.1M CH3COOH and 0.125M CH3COO- , both before and after addition of 10 mL of 0.25M HCl. Ka = 1.8 x 10-5.
What is the pH of a buffer that results when 0.50 mole of Na3PO4 is mixed with 0.75 mole of HCl and diluted with water to 1.00 L?
Provide me with your exact logic used to get the answer. A mysterious material was purified from safflower oil (hint: full of fatty acids). Upon ozonolysis it gave the following compounds in their respective molar ratios.
