Ring the filtration of the saturated ca(oh)2 the funnel is covered with a watch glass and afterwards the flask is stoppered. this is to minimize contact with the atmosphere/ why is this necessary? how would the observed ksp and solubility of ca(oh)2 be affected if contact with the air were not minimized?
Compute the molar mass that would be obtained from the actual experimental data under the subsequent conditions. The unknown is methyl propyl ether (CH3OC3H7) which has a vapor pressure of 375.2torr at room temperature, 20C.
225mL of a gas are collected over water at 22 C and 790torr. Explain the mass of the gas is 0.425 g as well as the vapor pressure of water at 22 C is 20torr. Explain what is the molar mass of the gas
A fixed quantity of gas at 24 C exhibits a pressure of 745 torr and occupies a volume of 4.40 L. Use Boyle's law to calculate the volume the gas will occupy if the pressure is increased to 1.88 atm while the temperature is held constant.
A gas occupies 10.0 L at 44.1 psi and 27 degrees C. What volume will it occupy at standard conditions
An attempt at synthesizing a certain optically active compound resulted in a mixture of its enantiomers. The mixture had an observed specific rotation of 12.4°.
what sort of interaction occurs between adjacent alcohol molecules? and what sort of interaction occurs between
Calculate the standard heat of reaction, or , for this reaction using the given data. Also consider that the standard enthalpy of the formation of elements in their pure form is considered to be zero.
The standard cell potential (Ecell) of the zinc-air battery is 1.65V. If at 25 degrees celcius the partial pressure of oxygen in the iar diffusing through its cathode is 0.22atm, what is the cell potential (Ecell)? Assume the cell reaction is:
She drinks a lot of water and has consume milk of magnesia(ph value 10.5) before she feels comfortable again. State the pH values of water and blood and whether its acidic or alkaline.
Sort the subsequent reactants into one of these three categories- arrhenius/bronsted- lowry acid, arrhenius base, bronsted- lowry base, based upon their actions in the reactions shown
How many grams of Cl2 can be prepared from the reaction of 15.0g of MnO2 and 30.0g of HCl according to MnO2 + 4HCl >> MnCl2 + Cl2 + 2H2O
36.45mL of 0.11 M hydrochloric acid were added to 36.45mL of 0.098 M aqueous barium hydroxide. Compute the theoretical yield of the salt produced.
