If the pH probe was miscalibrated and reports the pH and reports the pH to be 1 unit higher than the true pH of the solution it is in, would the molar mass you report for the solid acid be higher than, lower, or equal to the true molar mass of the acid?
Propose a structure for an amine of formula C4H9N, which liberates a gas when treated with NaNO2 and HCl. The 13C NMR spectrum is as follows
Describe briefly the trend in the stabilities of oxidation states within d-metal? [High and low oxidation states]
In the reaction below, 4.86 atm each of H2 and Cl2 were placed into a 1.00 L flask and allowed to react: H2(g) + Cl2(g) 2 HCl(g) Given that Kc = 89.9, calculate the equilibrium pressure of HCl.
calculate the pH of 50 ml of .15 M HCHO2 with 75 mL of .13 M NaCHO2
The Party Guy, Mr. Balloon, is making animal figures out of long thin balloons that he twists into different shapes. Assume that the balloons are of uniform thickness.
Consider that there is 26.38 g NaCl in a solution that has a total volume of 1,780 mL with a density of 0.8495 g/mL. A) What is the molarity of NaCl? B)What is the mass/mass %?
If the initial pressure of iodoethane is 894 torr at 245°C, what is the pressure of iodoethane after three half-lives?
moles of an ideal gas in an initial state T1 = 300 K and P1 = 0.5 bar undergo an isothermal compression until the pressure of the system is four times the original pressure
