A) Which one is acid?
B) How many moles of acid is needed to neutralize 1 mole of base?
C) How many moles HClO4 solution is needed to neutralize 30.00 mL of 0.0775 M NaOH?
D) What volume of 0.105 M HClO4 solution is needed to neutralize 30.00 mL of 0.0775 M NaOH?
What type of rotation axis does the structure have parallel to the [0 0 1] direction and show the location of this axis in a [0 0 1] projection of this crystal structure?
Wind provides a source of renewable energy that is increasingly being tapped. Modern wind tubines can conbert up to 30% of the kinetic energy of the incoming wind blowing through their blades to electicity.
Draw 2 resonance structures for the anion -CH2CHO formed from ethanol. Show all valence electrons as bonds or lone pairs and indicate any formal charges.
The lethal doses (expressed in ppm by volume) of two gases A & B are the same and equal to 20 ppm. Indicate how many mg of each gas would be needed to reach the lethal concentration in a room of 46m^3.
A carbon-hydrogen-oxygen containing compound yields 1.029 g CO2 and 0.198 g H2O in a combustion analysis( note that this means O2 was added the overall reaction) what is the empirical formula? if the Molar mass is 138.16 what is the molecular form..
Water cannot be used as a solvent for the Maleic anhydride + 1,3 cyclopentadiene because. so far all i have got is that anhydrides react toward water, and use dry reagents/apparatus. For a better yield of the cycloadduct.
In the Bohr model, the potential energy of a hydrogen atom in the nth orbit has a value we will call Un. What is the potential energy of a hydrogen atom when the electron is in the (n+1)th Bohr orbit. (Give your answers in terms of Un and n.)
You then tore off the corner, inserted filter paper in the funnel, and filtered your BaSO4 precipitate. How does this affect the percent sulfate you calculated; too low, too high, no effect
A particular system is doing work on the surroundings as well as gaining heat from the surroundings. What can be said about the values of q (heat) and w (work) for this system?
If 18.4 mL of 0.800 M HCl solution are needed to neutralize 5.00 rm mL of a household ammonia solution, what is the molar concentration of the ammonia?
the indicated ph value for the titration of 50.00 ml of .100 M benzoic acid (ka = 6.3 x 10^-5) with .0500 M KOH: ph = 4.20, 4.50.8.06, 11.50. write te reaction for KOH reacting with benzoic acid and the equilibrium for each pH value
How much heat in kilojoules is required to warm 10.0 g of ice, initially at -10.0^\circ C, to steam at 110^\circ C. The heat capacity of ice is 2.09 {\rm J}/{\rm g} ^\circ {\rm C} and that of steam is 1.84
