Find the pH of a 0.135 M aqueous solution of periodic acid (HIO4), for whichKa = 2.3 × 10-2.
Calculate the molar mass of a gas that has a density of 0.232 g/L at 156 oC and 222 torr. Use R = 0.0821 L-atm/mol-K for the value of the gas constant.
In a combustion reaction 4 moles of C8H18 react with 8 moles of O2. If the actual yield of CO2 produced is 28.16 grams, what is the percent yield?
what is the density of sample of ammonia gas if the pressure is 705mmHg and the temperature is 63.0 degrees C?
Calculate the entropy change when 1.86 g of H2 reacts with O2 according to the reaction 2H2(g) + O2(g) ! 2H2O(l) at 298 K and 1 atm pressure.
I need help describing an experiment where one could measure the value of the extinction coefficient of a solution with a concentration (c mol/L) of chlorophyll in water for a given wavelength.
Use this information to compare how long it will take to obtain molecular scale mixing of such a gas over i) distance 1*10^-4 m and ii) 10m
Determine the final concentration if A 134 ml portion of that solution is diluted using 147 ml of H 2 O?
Describe the preparation of 1.5 liters of a 0.1 M acetate buffer, pH 5.0, starting from solid sodium acetate trihydrate
Kp for this reaction is 5.1 x 10-2 atm-1. Initially, 1.00 g each of SO2 and Cl2 are placed in a 1.00 L reaction vessel. After 15 minutes, the concentration of SO2Cl2 is 45.5 μg/mL.
Find the molality of the solution. Find the molecular weight of the unknown compound please show steps
A 36.4 l volume of methane gas is heated from 15 degrees C to 98 degrees C at constant pressure. what is the final volume of the gas?
