For the gas N2O calculate the number of grams are present in 1.05E4 mL under a pressure of 801 mm Hg at 56.3 oC.
Consider the 1H19F molecule. The bond length of 1H19F is 91.7 pm. The wavenumber of light associated with a transition from the ground vibrational state to the first excited state is 1159.18 cm^-1.
A sample of zinc metal reacts completely with an excess of hydrochloric acid: Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g) The gaseous product is collected over water at 25.0oC and barometric pressure of 0.980 atm.
Furthermore, you conducted the experiment using Styrofoam coffee cups because of their effective insulation capabilities. Therefore, you were able to accurately measure the molar enthalpy change of the acid-base reaction.
A. Liquids have very strong attractive forces holding them together B. Liquids have moderately strong attractive forces holding them together C. Liquids have very weak attractive forces holding them together.
What is the minimum uncertainty in the position of an electron, given that we know nothing about its speed except that it is less than the speed of light?
Assume the temperature of the mixture is chosen so that Kp=0.12. Predict the effect on the partial pressure of SO3 as equilibrium is achieved by using Q, the reaction quotient.
