What wavelength of light would you report in units of nm, if the light had a wavelength of 7.60 x 10-10 m?
The NaHCO3 is the limiting reactant and the HCl is the excess reactant in this experiment. Determine the theoretical yield of the NaCl product.
a cylindrical glass tube 15cm in length is filled with ethanol. The mass of ethanol needed to fill the tube is found to be 9.64g. Calculate the inner diameter of the tube in centimeters. The density of ethanol is 0.789 g/mL
Some of the cyclohexane solvent vaporized during the temperature versus time measurement. Will this loss of cyclohexane result in its freezing point being recorded as too high, too low, or unaffected.
The density of liquid oxygen at its boiling point is 1.14kg/L , and its heat of vaporization is 213kJ/kg. How much energy in joules would be absorbed by 4.0 L of liquid oxygen as it vaporized.
For the equation: C (s) + CO2 (g) -> 2CO (g); the value of Kp is 167.5 at 1000 oC. If a 5.00 L container initially contains 2.99 atm pressure of CO2 (g) at 1000 oC, what are partial pressure of CO2 (g) and CO (g) at equilibrium?
