The pH of coffee is approximately 5.0. How many times greater is the [H3O+] in coffee than in tap water having a pH of 8.0?
A total of 0.155 of this subunit was dissolved in enough water to produce 2.00 of solution. At 28 the osmotic pressure produced by the solution was 0.138 . What is the molar mass of the protein?
Some velomobile seats have been designed to hold ice packs inside their cushions. If you started a ride with ice packs that held 1700 g of frozen water at 0 degrees C , and the temperature of the water at the end of the ride was 32 degrees C.
Write balanced nuclear equations for (a.) the loss of an alpha particle by thorium- 230 and (b.) the fission of U- 235 to give Ba- 140, two neutrons, and another nucleus.
What is the movement of electrons in an ammonia and hydrochloric acid reaction?
Calculate the transmittance of 162-nm radiation through a sample of ethylene gas at 25 oC and 10 torr for a cell length of (a) 1.0 cm; (b) 10 cm.
The osmotic pressure of a aqueous solution of a given polymer with mass concentration 0.300 g/mL is 10.0 torr at 298 K. Estimate the molar mass of the polymer.
What is the value of q when 0.0209 g of water vaporizes at 373 K? The enthalpy of condensation of water at 373 K is -40.7 kJ/mol.
Which of the following represents the maximum available useful energy when a system changes spontaneously from a given initial state to a given final state
The iron content of an ore can be determined by a redox titration using K2Cr2O7 as the titrant. A sample of the ore is dissolved in concentrated HCl using Sn2+ to speed its dissolution by reducing Fe3+ to Fe2+.
To better understand why, scientists synthesized artificial protein mimics that were linked by ester bonds instead of the amide functionality ( the R-group side chains all remained the same). They found that these mimics did not form highly organi..
