Maleic acid is a carbon-hydrogen-oxygen compound used in dyeing and finishing fabrics and as a preservative of oils and fats.In a combustion analysis, a 1.054- sample of maleic acid yields 1.599 of and 0.327 of.
When 0.609 of maleic acid is dissolved in 25.00 of glacial acetic acid, the freezing point drops by 0.82 . Maleic acid does not ionize in glacial acetic acid, which has a freezing-point depression constant of.
In a titration experiment, a 0.4250- sample of maleic acid is dissolved in water and requires 34.03 of 0.2152 for its complete neutralization.The of 0.215 of maleic acid in 50.00 of aqueous solution is found to be 1.80.
A 4.10 g nugget of pure gold absorbed 274 J of heat. What was the final temperature of the gold if the initial temperature was 27.0°C? The specific heat of gold is 0.129 J/(g·°C).
what is the minimum amount of KCN (in g) needed to react with 15.6 g of gold?
A 486 mL sample of water was cooled from 50.0°C to 10.0°C. Assuming a specific heat of 4.184 J/K g and a density of 1.00 g/mL, find the amount of heat transferred from the water to the surroundings.
Calculate the pH of a buffer that contains 0.270 M hydrofluoric acid (HF) and 0.180 M cesium fluoride (CsF). The Ka of hydrofluoric acid is 6.80 x 10^-4.
Assuming that the volume of a solid or liquid was independent of the external pressure, we deduced that there was no change in the Gibbs free energy of a solid or liquid when the pressure is changed.
In respiratory acidosis, as the CO2 concentration decreases in the bloodstream, the concentration of H3O+ decreases, and as a result, the pH decreases below the normal range.
a solution is prepared by dissolving 23.7g of CaCl2 in 375g of water. The density of the resulting solution is 1.05g/mL.
linear polystyrene has phenyl groups that are attached to alternate not adjacent carbons of the polymer chain
What volume (in milliliters) of 0.240 M NaOH should be added to a 0.125 L solution of 0.029 M glycine hydrochloride
what is the percent by mass of a solution on made by dissolving 163 grams of table sugar in 755 grams of water.
calculate the difference in mass that is hold by a 500.0mL flask at a temperature of 0.0°C from that at temperature of 20.0 °C? (you can assume the volume of the sample at 0.0 °C temperature =volume of the sample at 20.0°C)
he maximum contaminant level (MCL) for barium (Ba) in drinking water is 2.0 mg/L. Barium can combine with sulfate (SO42-) to form BaSO4(s), which precipitates out of the water. This can be achieved by adding Na2SO4
