You have to be careful about pouring drano down your pipes since it is mainly hydrochloric acid--you can't do it if they are made of aluminum because it will dissolve them! You can't acid clean your aluminum auto parts for the same reasons: 2 Al + 6 HCl → 2 AlCl3 + 3H2. If you wanted to make 10.0 moles of hydrogen gas, how many many moles of Al would you need? NOTE: All numbers located immediately after elemental symbols should be considered subscripts.
Then rotovap until crystallized and add 20 mL cold H2O, stir +10% HCl to neutralize. Filter and wash.
lemon juice is a complex aqueous solution that does not freeze in ahome freezer at temperatures as low as -11 degc. at
Determine ΔG for this reaction When A is full into a cylinder at a pressure of 9.89 atm and the system is permitted to come to equilibrium, the final pressure was 15.94 atm.? Express your answer in units of kJ/mol
Oxalic acid dehydrate, H2C2O4. 2H2O (formula weight = 126.1 g/mol) is sometimes used to standardize NaOH solutions. How many grams of this acid will be required to titrate 45.0 mL of 0.18 M NaOH solution
Calculate the value of Keq for the following equilibrium when [H2]=0.228M, [I2]=0.228M and [HI]=1.544 H2 + I2 -> 2HI
One cup is equivalent to 237. mL. If 1 cup of oil has a mass of 210. g, what is the density of the oil (in grams per cubic centimeter)?
Question- Blood pH lies within the narrow range 7.35 - 7.45. The principle buffer mechanism is shown as the biocarbonate/carbonic acid equilibrium:
The volumes(45.01,45.05,45.07, and 45.33)ml were used to titrate a 50ml aliquot of a sample. would you reject any values at a 90% confidence interval. how about a 95% confidence interval
neutral compound show traces of an acid as an impurity wheras the acid might not show any traces of a neutral compound?
Problem- In the photochemical decomposition of a certain cmpd, light intensity of 5.4 x 10^-6 einsteins s^-1 was employed. Assuming the most favorable conditions, estimate the time needed to decompose 1 mole of the compound.
