Background: If aqueous NaOH is added to tert-butyl chloride acetone solution, initially the solution is basic due to the hydroxide ions from the NaOH. As the t-butyl chloride continues the reaction through hydrolysis and generates HCl, the HCl neutralizes the NaOH ions
Question: If 5.0mL of 0.0091M aqueous NaOH is added to 5mL of 0.091M of tert-butyl chloride in acetone, calculate the pH at 10% hydrolysis. (There is a hint listed that says to calculate moles of HCl produced and compare that number to the moles of NaOH present in the reaction mixture.)
The atomic weight of a newly discovered el- ement is 110.352 amu. It has two naturally occuring isotopes. One has a mass of 111.624 amu.
Mg3N2(s) + 3 H2O(l)= 3 MgO(s) + 2 NH3(g) How many moles of Magnesium oxide are produced by the reaction of 3.82g of Magnesium nitride with 7.73g of water?
A solution containing 100g of an unknown substance and 900g of water. The solution has a Freezing Point of -3.33*C. What is the molar mass of the substance?
An increase in the temperature of the reactants causes an increase in the rate of reaction. The best explanation for this behavior is that as the temperature increases
Explain why higher levels of defects are found in solids at high temperatures and close to their melting points.
