Considering the given equation C3H8(g) + 5O2(g) = 3CO2(g) + 4H2O(g) in which Propane and oxygen reacts Compute the volume of CO2 and water vapour produced and the volume of oxygen remaining, when 20.0 dm3 of propane reacts with 120.0 dm3 of oxygen. All gas volumes are measured at the same temperature and pressure.
How many grams of KNO2 must be added to 5.00 liters of 0.67 M HNO2 solution to produce a buffer with pH = 3.15?
A voltaic cell is constructed by immersing a strip of silver metal in a 1.0 M AgNO3 solution and a strip of cadmium metal in a 1.0 Cd(NO3)2 solution. The circuit is completed by a wire and a salt bridge in the usual way.
Find the standard change of entropy for the formation of CH2Cl29g) from its gaseous elements in their standard states. Please show and explain how you got the answer. Specifically how you came up with a balanced equation.
A mixture of nitrogen and hydrogen was allowed to come to equilibrium at a given temperature according to 3H2+N2 2NH3. At equilibrium, the mixture contained
The 13C nucleus is a spin 1/2 particle, which means it can orient in two directions in a magnetic field (with the field and against it). The difference in energy between the two orientations is given by:
Why do solutions of iodide ion in water appear yellow when I- is oxidized to I2 by a suitable oxidizing agent, while solutions of I- in CCl4 or CHCl2 appear violet when the same oxidationis done?
Using the alpha diagram for carbonate in a closed system, at what pH would the molar CO2 concentration be approximately equal to the molar bicarbonate concentration
Consider the following reaction: NH4HS(s) NH3(g) + H2S(g) An equilibrium mixture of this reaction at a certain temperature was found to have [NH3]=.278M and [H2S]=.355M.
What ions are in these solutions. cold tap water, 0,9 % NaCl (aq), 0,1 M acetic acid, 0,1 M HCl, 0,1 M NaC2H3O2 (aq), 0,1 M ammonia.
A.) If 75.0 g of sodium is mixed with 40.0 g of nitrogen gas, what mass of sodium nitride forms? B.) If the reaction in part A has a percent yield of 90 % , how much sodium nitride is actually produced
smaller dipole moment than formaldehyde, H2C=O, even though it contains electronegative chorine atoms in place of hydrogen. Explain
what would be the effect on my calculated molecular weight of p-dichlorobenzene if my lab partner left the stopper off of the apparatus while I was weighing the solid p-chlorobenzene. Explain in detail what would happen if this occured and how it ..
