A certain titration is carried out using the following unbalanced equation:
H2SO4(aq) + NaOH (aq) --> H2O (l) + Na2SO4(aq)
If 37.89 mL of 2.0 M sodium hydroxide are used to titrate a 45.00 mL sample of sufuric acid, what is the molarity of the acid?
Enter only the number rounded to the correct number of significant figures; do not enter any units.
How much heat is required to vaporize 55.8g of acetone at its boiling point? The heat of vaporization of acetone at its boiling point is 29.1 kJ/mol
Question- You titrate 25.00ml of 0.03130M Na2CO3 with 0.02600M Ba(NO3)2. Calculate the pBa2+ after the following volumes of Ba(NO3)2 are added. Ksp for BaCO3 is 5.0 x 10-9.
Below is the 1H NMR spectrum of the following triazine structure. In the expansions of the spectrum, place the observed multiplicity in the bin above the resonance.
What pair of elements would you expect to exhibit the greatest similarity in physical and chemical properties. WHY.
The following solutions are mixed: 35.0 mL of 0.200 M Ca(OH)2 are mixed with 60.0 mL of 0.125 M HBr. What is the pH of the resulting solution. Assume additive volumes.
If the step for digesting the precipitate were omitted, will the reported "percent limiting reactant" in the salt mixture be too high, too low, or unaffected
Concentrated hydrochloric acid is 37.5% HCL by mass as well as has a density of 1.205g*cm^-3. Explain what volume in Ml of concentrated hydrochloric acid must be used to prepare 10.0l of 0.7436m HCL(aq)
When 414 J of heat is added to the gas, it expands and does 104 J of work on the surroundings. What is the value of delta H?
Calculate the standard enthalpy. of formation of solid Mg(OH)2 using the following thermochemical info: Mg (s) + O2 ---> 2MgO(s) delta H = -1203.6 kj Mg(OH)2 (s) ----> MgO (s) + H2O (l) delta H = 37.1 kj 2H2 (g) + O2 (g) ----> 2H2O(l) delta H = -5..
Molarity is only one of many ways to express concentration. Another is percent mass per volume or %(m/v). For example, vinegar usually contains about 5 %(m/v) acetic acid(5g acetic acid/100 mL vinegar)
It takes 17.87mL of 0.002587 M K2Cr2O7 to reach the endpoint. Define what is the nitrite concentration in the original waste water sample measured in mg /L
