The first-order rate constant for the reaction of methyl chloride (CH3Cl) with water to produce methanol (CH3OH) and hydrochloric acid (HCl) is 3.32 10-10s-1 at 25°C. Calculate the rate constant at 37°C if the activation energy is 116 kJ/mol.
Calculate the pH of 100. mL of 0.31 M NH3 before and after the addition of 4.5 g of NH4NO3, and account for the change. Assume that the volume remains constant.
how many moles of hydrogen ions were converted to water when 85. ml of 1.0 M hydrochloric acid were neutralized by sodium hydroxide.
How many milliliters of 0.410 M KOH solution are needed to completely neutralize 48.2 mL of 0.151 M HI solution? The reaction is KOH(aq) + HI(aq) ? KI(aq) + H2O(l)
The generic metal hydroxide M(OH)2 has Ksp= 6.64x10^-18. (Note: In this particular problem, because of the magnitude of the Ksp and the stoichiometry of the compound, the contribution of OH from water can be ignored. However, this may not always b..
