pH of a saturated solution of Ba(OH)2 is 12. The value of solubility product (Ksp) of Ba(OH)2
Enough of a monoprotic acid is dissolved in water to produce a 0.0197 M solution. The PH of the resulting solution is 6.41. Calculate the Ka for the acid.
the running engine of an automobile produces carbon monoxide at the rate og 188 g co per hour.a car is left idling at
Iodine-131 decays to produce xenon-131. Which type of nuclear radiation is emitted in this reaction
A chemical engineer studying the properties of fuels placed 1.500 g of a hydrocarbon in the bomb of a calorimeter and filled it with O2 gas. The bomb was immersed in 2.500 L of water and the reaction initiated.
How many moles of hydrogen gas are produced when 0.066 mole of sodium is completely reacted?
When would formation of a derivative be a necessary step in this experiment?
The solubility of the ionic compound M2X3, having a molar mass of 238 g/mol, is 2.89 10-7 g/L. Calculate the Ksp of the compound
below, 8.34 atm each of H2 and Br2 were placed into a 1.00 L flask and allowed to react: H2(g) + Br2(g) 2 HBr(g) Given that Kc = 86.7, calculate the equilibrium pressure of Br2.
Even if two spots have the same Rf value, we cannot be certain that the two samples are identical compounds. suggest a good method to confirm that the two samples are the same or not the same.
Write the expressions for Kc for the following reactions. a. 2O3(g) --> 3O2(g) b. Ti(s) + 2Cl2(g) --> TiCl4(l) c. 2C2H4(g) + 2H2(g) --> 2C2H6(g) + O2(g)
What is the pH of a solution made by mixing 30.00 mL of 0.10 M acetic acid with 30.00 mL of 0.10 M KOH? Assume that the volumes of the solutions are additive. Ka = 1.8 × 10-5 for CH3CO2H.
