Oxygen gas most closely exhibits ideal behaviour under conditions of (high/low) temperature and (high/low) pressure.
Taking into account that standard pressure is about 100 kPa, what would happen to the amount of oxygen available to cells if the chamber pressure had a pressure of 120 kPa? The oxygen level in the cells would (increase/decrease) by about 20% because the same amount of oxygen would take up 20% (less/more) space.
Calculate pH change if 1ml of HCl were added to 30.0ml of pure water instead of the buffer solution.
barium hydroxide solution PH = 10.5 is needed. How many grams of Barium hydroxide are needed
Titrated with 0.10 M HBr. Determine the pH of the solution after the addition of 400.0 mL HBr.
Determine the boiling point of an aqueous solution that is 2.30 m ethylene glycol (C2H6O2); Kb for water is 0.52 degrees celsius/m.
Depict all of the stereoisomers that result when (E)-hex-2-ene is hydrogenated with D2 over a metal catalyst. All hydrogen atoms are implied, however any deuterium isotopes must be shown where appropriate.
Can anyone show a picture or a link to show me the mechanism for maleic acid to fumeric acid and include where the electrons are transferred from and where they are going
What is meant by kinetic energy vs potential energy when comes electricity?
Use the polygon in circle method to construct a pie molecular orbital diagram for the benzene dianion c6h6 -2 and explain why, on this basis, you would or would not expect it to be stable.
The balance used to measure the mass of the metal reads low (for example, it reads 19.4 g instead of an actual 19.7 g). How will this error, due to miscalculation of the balance, affect the reported specific heat value for the metal. Explain.
One mole of hydrogen at 25c and 1 bar pressure is compressed adiabatically and reversible into a volume of 5 L. Assuming ideal gas behavior, calculate
After filtering off this precipitate, the pH is adjusted to 8 and H2S is again added; no precipitate forms. No precipitate forms upon addition of (NH4)2HPO4. The remaining solution shows a yellow color in a flame test. Based on these observations,..
