What is the pH when enough 0.100 base is added to neutralize 8.00 mL of 0.100 M acid? Note: Make simplifying assumptions, do not use the quadratic formula. Using HC2H3O2.
How much HCl is produced from the reaction of an excess of HSbCl4 with 3 moles H2S in the following reaction? HSbCl4 + H2S ! Sb2S3 + HCl
Imagine that you have two iron blocks, one with a mass 226 g at a temperature of 46.0 oC, and another with a mass 380 g at a temperature of 134 oC. The two blocks are brought into contact with each other in an insulated container. What is the fina..
corrosion technologist pipetted a 100.00 mL hard water sample and titrated it with 37.64 mL of 0.01 M EDTA solution for a total hardness endpoint
Combustion of a 0.1000 g sample of a compound containing only carbon, hydrogen, and oxygen in excess yields 0.1953 g CO2, and 0.1000 g H2O. A separate experiment shows that the molar mass is 90 Daltons. Calculate the mass percent composition.
What is the molar mass of a gas if 0.250 g of the gas occupies 215 mL at 618 mmHg and 30.0°C?
At a given temperature, 1.40 atm of H2 and 2.03 atm of I2 are mixed and allowed to come to equilibrium. The equilibrium pressure of HI is found to be 1.305 atm. Calculate Kp for the reaction at this temperature.
what is the broglie wavelength of an electron moving at one-tenth the speed of light. mass of the electron = 9.109* 10^-28
A sample of hydrogen occupies a volume of 1.20 liters at a pressure of 425 kilapascals. If the temperature of the gas is constant, what would the new volume of the gas be at 615 kilapascals?
What molar ratio of sodium acetate to acetic acid (NaAc/HAc) should be used in preparing a buffer having a pH of 4.35? (Ka = 1.8×10-5 for acetic acid.)
The normal boiling point of ether is 307.8 K. Calculate the temperature at which its vapor pressure is exactly half of that at its normal boiling point.
